The Phrozen Sonic Mini 4K is an affordable entry in the increasingly-competitive resin 3D printer market which offers high resolution at a low cost. If you’re interested in printing small models or objects and capturing as much fine detail as possible, the Phrozen Sonic Mini 4K is a machine that may work for your application. The build volume of the Sonic Mini 4K is typical for resin machines in this price range, but the high Pixels-Per-Inch density makes this one of the best 3D printers you can buy.

Printing Safety with Phrozen Sonic Mini 4K
(Image credit: Tom's Hardware)As with all resin 3D printers, you need to be careful when using the Sonic Mini 4K. Uncured resin can be dangerous , so you must wear gloves and eye protection when pouring it or handling parts that have uncured resin on them.
Make sure you use the printer in a well-ventilated room to minimize the danger from inhaling fumes. Any spills or uncured resin stuck to a surface should be cleaned using 99% Isopropyl Alcohol and the container for the resin should be kept closed and secured when not actively pouring material.
Assembling the Phrozen Sonic Mini 4K
(Image credit: Tom's Hardware)It took me less than an hour to get the printer assembled and printing, which is typical for a resin printer like this one. The external power supply plugs into the back of the printer, and the cover simply sits on top of the base of the unit. The build platform slides into place on the Z axis gantry and is calibrated as a separate step.
Calibrating the Build Plate on the Phrozen Sonic Mini 4K
(Image credit: Tom's Hardware)Similar to FDM 3D printers, the build platform on a resin 3D printer requires calibration to create an even surface. The Sonic Mini 4K uses an adjustable build platform with four screws to offset the surface and compensate for any uneven surfaces.
The calibration process is more involved than on a printer like the Elegoo Mars 2, because there’s no ball and socket design on the platform. A ball and socket design allows the platform to be leveled using only two screws and offers a high level of accuracy, as opposed to a four screw system which is easier to manufacture but harder to adjust.
Adjusting the corners of the platform is difficult due to the tension put on the platform from the mounting bracket and the configuration of the bolts makes it difficult to make any adjustments while leveling.
The interface of the printer indicates that the vat should be removed during leveling, but the user manual says that the vat should be left in during leveling. Leveling with the vat installed can potentially damage the delicate FEP screen, so this may cause confusion and frustration for users inexperienced with leveling the build platform on a resin 3D printer. A piece of coarse 80-grit sandpaper is included for roughing up the build surface, but this can also lead to problems with the FEP being punctured if the platform is unevenly sanded or scuffed.
Printing Workflow on the Phrozen Sonic Mini 4K
(Image credit: Tom's Hardware)The typical workflow for printing a part on a resin printer is generally a bit more involved than doing the same on a filament printer.
Phrozen has added a profile for the Sonic Mini 4K to the popular software ChituBox, which allows for out-of-the-box compatibility. The ChituBox software can hollow a model, add drain holes, add support structures, and output a file compatible with the printer using the .CTB file format. The Sonic Mini 4K uses a USB thumb drive for file storage, and the touchscreen UI allows you to select a file, see a thumbnail preview, and start the print.
Printing the AmeraLabs Calibration Test on the Phrozen Sonic Mini 4K
(Image credit: Tom's Hardware)For testing the fine features that are printable on resin printers, resin manufacturer Ameralabs has created a test part called Ameralabs Town that has very fine posts, holes, text, and other details. I made this calibration print using the default settings from Chitubox and Elegoo Beige Standard Resin. Unfortunately, the initial output was disappointing, because the difficulty I had getting the build platform level led to the first few layers being compressed and a loss of some of the small detail.
Settings
| Layer Height | 0.05 mm |
| Bottom Exposure Time | 25 seconds |
| Exposure Time | 2.2 seconds |
| Bottom Layer Count | 6 |
Machining issues on the Phrozen Sonic Mini 4K
(Image credit: Tom's Hardware)After fully disassembling the build platform, it became apparent what the issues were. The bracket that holds the platform had not been bent properly, and the holes for the screws had not been machined properly and had metal shavings that were falling out. Given that this component sits directly above the thin and delicate FEP vat, this is a serious oversight that could potentially lead to a piece of metal piercing the film.
After I manually bent the bracket, cleared the threaded holes, and releveled the platform, the second print showed substantial improvement. Phrozen should have detected and resolved these non-trivial build issues at the factory.
While experienced users could diagnose and rectify these problems, they would prove frustrating to a new user who could inadvertently damage the machine.
Printing busts on the Phrozen Sonic Mini 4K
(Image credit: Tom's Hardware)To test out the detail on larger parts, after recalibrating, I printed this bust of Julius Caesar from The Metropolitan Museum of Art. The detail on the model is crisp and sharp, with the layer lines only barely visible under harsh directional light.
(Image credit: Tom's Hardware)The support structure detached without much effort, and left only small marks where it had attached to the model. The uncured resin inside the model drained through the holes in the bottom of the base and the sharp detail of the model (especially around the eyes, which have visible pupils) came into focus after I dried and cured the model. Considering this level of detail was possible using the default settings, it’s certainly worth considering the level of detail one could achieve after dialing the machine in to a specific resin.
For the price, the Phrozen Sonic Mini 4K offers very high resolution, a modest build volume, and plug-and-play software compatibility. For an experienced user who isn’t afraid of troubleshooting the calibration process of the Z axis, this 3D printer is a great choice for making highly detailed miniatures and other small models. However, beginners looking to get into resin printing would benefit from a machine with a simpler calibration process, such as the Elegoo Mars Pro.

The larger counterpart to the Elegoo Mars series of printers, the Elegoo Saturn is a large-volume resin MSLA 3D printer that has found a way to offer increased build volume without sacrificing part quality.
By increasing both the size and the resolution of the masking Mono LCD, the Elegoo Saturn is able to offer the same XY resolution of the Mars 2 Pro while increasing the total build volume.
One of the best 3D printers, the Saturn impressed me with how easy it was to set up and use but the scarce availability of the typically $500 printer may be a source of frustration when searching for one to buy.

Included in the Box of Elegoo Saturn
(Image credit: Tom's Hardware)The Elegoo Saturn ships in a well-packed box and includes all of the accessories you need to start printing as soon as the printer is out of the box.
Included in the accessories box is a metal scraper (for removing parts from the build platform), a plastic scraper (for removing parts from the FEP sheet and stirring the resin), some paper funnels with a wire mesh (for filtering resin), wire cutters (for removing support material), latex gloves, and a healthy number of spare bolts, Allen keys, and other easy-to-lose parts. The included USB stick comes pre-loaded with a test print, the Chitubox slicer app, a digital copy of the user manual, and a few files from the 3D model repository site MyMiniFactory.
Elegoo shipped this Saturn with a ‘tomshardware.com’ sticker applied to the UV-resistant lid, which was a nice touch for a review unit. As far as I can tell, this is the only difference between this unit and a typical retail unit, so my experience with this printer should be similar to yours if you purchase it directly from Elegoo.
(Image credit: Tom's Hardware)The Saturn is a typical resin MSLA 3D printer which utilizes a vat of resin, a masking LCD, a UV light source, and a single axis of movement.
It took me under five minutes to assemble this printer, and most of that time was removing foam and packaging from the box. The printer doesn’t require any mechanical or electrical assembly, and only needs to be calibrated before printing. The calibration process is almost effortless (more on that later), and the out-of-the-box experience felt quick and easy.
Image 1 of 2
(Image credit: Tom's Hardware)(Image credit: Tom's Hardware)The Saturn uses an 8.9-inch masking LCD with a resolution of 3840 x 2400, which gives it an effective XY resolution of .05mm. The masking LCD ships with a pair of protective stickers on it during shipping, and I had no problem removing them before printing. The black protective tape around the masking LCD needs to be left on the machine, and the manual makes sure to mention this first so a new user doesn’t accidentally remove it while removing the rest of the stickers.
Image 1 of 2
(Image credit: Tom's Hardware)(Image credit: Tom's Hardware)The resin vat on the Saturn uses four bolts that protrude from the bottom as locating posts which makes locking the vat into place a fast and repeatable process.
One of the biggest problems I have when cleaning resin vats is that they typically sit with the delicate FEP film flush against the surface they are laid down on, so even a small bump in a table can possibly dent or deform them. The four posts on the corners of the Saturn’s vat keep the FEP film slightly elevated during cleaning, which is a small feature but a welcome change in design.
The resin vat also has a max fill line printed right on it which takes away the stress from potentially over-filling and spilling resin. This feature, along with the spout that is molded into the vat, indicates that Elegoo has put some thought into the needs of users who are frequently changing vats or draining and replacing resin.
Image 1 of 2
(Image credit: Tom's Hardware)(Image credit: Tom's Hardware)Unlike most resin MSLA 3D printers which use a single linear rail for the Z axis, the Saturn uses a threaded leadscrew and a pair of linear rails for added stability. The Saturn features a larger build volume than most MSLA 3D printers, which means more weight is suspended from the cantilevered build platform.
Between these two rails and the solid machined bracket for the build platform, the Saturn is able to print without bending the build platform bracket during lift moves, and I was impressed with the rigidity of the system.
The Saturn uses a USB stick for transferring files to the printer, as well as an Ethernet connection for adding the machine to a network. If you’re interested in using the Saturn as part of a high volume print farm, the ability to network the machine means you can transfer files without the need for an external drive. The two fans on the back of the unit provide airflow for the controller board and UV LED light source, but don’t provide air filtration like the fan in the Elegoo Mars 2 Pro. Despite the lack of air filtration, the Saturn didn’t seem to emit an odor any worse than the Mars 2 Pro during printing, but if you’re concerned about air quality you’ll want to take this into account.
Leveling the Build Platform on Elegoo Saturn
(Image credit: Tom's Hardware)When printing on an MSLA resin 3D printer, you want the build platform to be perfectly level with the FEP film so the resin cures evenly across each layer.
This leveling process can be a challenge for beginners and it can be frustrating to have failed prints due to poor bed leveling. Elegoo has addressed this problem by using a unique leveling process that is fast, simple, and easy to complete. The Elegoo Saturn uses a build platform held rigid by two bolts and includes simple step-by-step instructions for the leveling process.
Image 1 of 2
(Image credit: Tom's Hardware)(Image credit: Tom's Hardware)After loosening the two bolts on the build platform and placing the included piece of leveling paper over the masking LCD, I dropped the Z axis to the home position and watched as the build platform self-leveled and sat perfectly flush. Once the axis had come to a rest, I simply tightened the two screws in the order indicated and lifted the build platform up. Compared to the leveling process on a printer like the Longer Orange 10 that uses four screws that need to be tightened in a star pattern and tend to shift during tightening, the Saturn feels almost effortless to set up.
Printing Safety with Elegoo Saturn
(Image credit: Tom's Hardware)The Elegoo Saturn uses 405nm UV resin, a material that you need to handle safely when in an uncured state to avoid injury. The resin can be harmful when making contact with skin, so make sure to wear gloves when pouring, cleaning up, or handling uncured resin. I also make sure I’m wearing gloves when removing the build platform after a print, as the resin tends to pool on top of the platform and can drip off while the platform is being removed.
Make sure you use the Saturn in a well-ventilated room to minimize the danger from inhaling fumes. Any spills or uncured resin stuck to a surface should be cleaned using 99% Isopropyl Alcohol and the container for the resin should be kept closed and secured when not actively pouring material.
(Image credit: Tom's Hardware)The build platform on the Saturn is designed with a trapezoidal shape that allows uncured resin to drip off and prevents it from pooling on the top of platform during printing.
Despite this shape, I noticed that resin had a tendency to collect at the very edge of the platform, and I couldn’t help but wonder if a more aggressive angle or a chamfered edge would help to allow more resin to drip back into the vat during printing. This is a relatively minor point, as the majority of resin will drip downwards during printing and cleaning the edge of the build platform doesn’t require much effort.
Printing the Included Test Prints on the Elegoo Saturn
Most 3D printers include a prepared test print as an opportunity for the manufacturer to demonstrate the strengths of their machine. Despite this relatively simple premise, I’ve found that test prints can be a source of frustration for first time users as they have a tendency to have issues that most first-time users won’t be expecting.
Image 1 of 2
(Image credit: Tom's Hardware)(Image credit: Tom's Hardware)Unfortunately, the Elegoo Saturn falls short in this category and my experience with the included test print was really the only major disappointment I had while writing this review.
The Saturn includes a test print on the included USB drive called “_Rook_SATURN.ctb” that consists of two chess pieces with fine details on the interior and exterior of the model. This test print completes in a very reasonable 3 hours and 49 minutes, and I was impressed with the fine detail on the models once the print had completed. Unfortunately, this is where things took a bit of a turn.
The build platform on the Saturn has a sandblasted textured finish which helps cured resin adhere during printing and prevents parts from delaminating. When removing a part, a thin raft can be bent (as seen in the picture above), which allows the part to easily detach from the build platform without too much trouble. This is a delicate balance; too thin and the part won’t adhere to the plate, too thick and the part can’t be easily removed. I had no trouble with any of the parts I sliced in Chitubox, but as you’ll see below, the included test print was significantly more difficult to remove.
Once printed, the detail on the rooks was impressive, but the solid base of the model printed directly on to the build plate didn’t present an intuitive method of removal. After using the included metal scraper and attempting to gently pry the parts off, I wondered if this was a common problem or if the Elegoo Water Washable Ceramic Grey resin I was using simply wasn’t compatible with the settings provided. A quick Google search for “Elegoo Saturn Test Part Stuck To Plate” shows that this is not an uncommon problem, with some users resorting to using a rubber mallet to remove the parts from the build plate.
(Image credit: Tom's Hardware)I was eventually able to remove the prints from the bed, but it required significantly more effort than I was comfortable with and resulted in both parts being chipped along the bottom layer. This could have been avoided with a demo model that was suspended from a support structure or simply used a sacrificial raft during printing to prevent such a wide and thick model being printed directly on the build plate.
It’s worth noting this was the only time I experienced this issue during this review. The rest of the parts I prepared using Chitubox for printing were easily removed and didn’t require excessive force to remove from the plate.
Preparing Files for Printing with Chitubox
(Image credit: Chitubox)The Elegoo Saturn uses Chitubox for slicing, preparing, and exporting files for 3D printing. Chitubox is a feature-rich program which reduces the need for secondary programs to generate supports, hollow models, or make other changes that would typically require a longer workflow. The general process for preparing a 3D model for resin 3D printing goes like this:
- Import 3D model
- Angle model for printing (avoiding wide per-layer cross-sections)
- Hollow model
- 4Add drain holes
- Generate support material
- Slicer
- Delete islands
- Export printable file
Chitubox makes this easy, as each step can be accomplished within the software without the need to export the file to various third-party softwares.
Chitubox also includes a built-in profile for the Elegoo Saturn which gives good quality results without any tweaking or modifications. I’ve been a fan of Chitubox since I started using it, and the ease-of-use and native support for the Saturn makes it a logical choice.
The profile for the Saturn that is included with Chitubox is what I would consider a good starting point for base settings. The Z resolution of .05mm is high enough to give a good quality print, but not so high as to cause an excessively long print time. The per-layer cure time of 2.5 seconds makes the Saturn a speedy printer when compared to machines with 9 second per-layer cure times like the Creality LD-002R.
(Image credit: Tom's Hardware)For a first test, I used the Ancient Statue model from Loot Studios and prepared it using the default settings in Chitubox without making any modifications. For resin, I used the Elegoo Water Washable Ceramic Grey , which has worked very well for me in the past on the Elegoo Mars 2 Pro.
This model used about 28 grams of resin and printed out in just under 4 hours, which seems in line with what I would expect from a Mono LCD 3D printer.
Image 1 of 2
(Image credit: Tom's Hardware)(Image credit: Tom's Hardware)The Water Washable Ceramic Grey resin looked great after printing, and the support structure removal process is simplified by not requiring any isopropyl alcohol or other chemicals to remove the excess resin. A quick soak in a small tub of hot water dissolved the excess resin from the surface of the printer and also softened the support structure. After removing the support structure, I cured the model for a total of two minutes in 30 second increments to prevent it from warping.
(Image credit: Tom's Hardware)It’s worth taking a moment to reflect on the printing process so far before we really look at this model. The steps to create this model are all simple and straight-forward, and a beginner could easily follow along to calibrate the bed, fill the resin vat, and process the file for printing.
The resulting print looks sharp and detailed, and even small details like the cracks in the stone of the statue resolve and don’t require any touch-up work. Putting aside the large format nature of the Elegoo Saturn, it’s easy to understand why this machine is in such demand; it’s easy to use, gives good quality results, and the native software doesn’t require tinkering or tweaking.
Print Size Comparison of the Elegoo Mars 2 Pro vs. Elegoo Saturn
Image 1 of 2
(Image credit: Tom's Hardware)(Image credit: Tom's Hardware)The Elegoo Saturn shares many design similarities with the Elegoo Mars 2 Pro, so it makes sense to compare the two 3D printers directly. The Saturn uses a higher resolution masking LCD, but the increased size of the LCD means the XY resolution (pixel size) is .05mm on both machines. This means a part printed on the Mars 2 Pro and Saturn, using the same settings, will result in two parts that should be indistinguishable from one another.
| Elegoo Mars 2 Pro | Elegoo Saturn | |
|---|---|---|
| Masking LCD Resolution | 1620 x 2560 | 3840 x 2400 |
| XY Resolution | . 05mm | .05mm |
| Build Dimensions | 5.08 x 3.15 x 6.3 inches | 7.55 x 4.72 x 7.87 inches |
| Build Volume | 100.81 cubic inches | 280.46 cubic inches |
| Printer Dimensions | 7.87 x 7.87 x 16.14 inches | 11.02 x 9.44 x 17.55 inches |
| Printer Volume | 999.66 cubic inches | 1825.70 cubic inches |
| Build / Footprint Ratio (higher is better) | 10.0% | 15.4% |
With a retail price of $500, the Saturn offers nearly 3 times the total build volume (280 cubic inches vs. 100 cubic inches) of the Mars 2 Pro, which retails for $330. If you’re interested in throughput and high-volume printing ability, the Saturn is able to produce a large batch of parts at the same resolution as Mars 2 Pro. However, if you’re looking for a higher resolution finished part and aren’t interested in a large build size, a 4K LCD printer like the Phrozen Sonic Mini 4K would be a better choice.
Image 1 of 2
(Image credit: Tom's Hardware)(Image credit: Tom's Hardware)Printing a Large Assembly on the Elegoo Saturn
(Image credit: Tom's Hardware)The large build volume and fast per-layer print time of the Elegoo Saturn make it ideal for printing models that would ordinarily be too large or time-consuming to print on a smaller MSLA resin printer like the Longer Orange 10. To test out the ability of the Saturn to print large models in multiple pieces simultaneously, I loaded up the Olympus Rider model from Loot Studios. This model of a winged Pegasus complete with rider armed with a spear prints in six individual pieces and a single large base.
(Image credit: Chitubox)Unfortunately, the auto-placement feature in Chitubox wasn’t able to automatically place all of these parts on the build platform in order to print them in a single piece. After manually rotating the parts myself, I was able to get everything except the base of the model onto a single tray.
This would be an ambitious print under the best of circumstances, as it covered a large portion of the surface area of the build platform and would create a large amount of suction when moving the platform up and down. After slicing, Chitubox generated an estimated build time of 7 hours and 10 minutes as well as a material usage of 128 ml. I wasn’t sure if the Saturn could handle a print this ambitious, but I was eager to see if this hard-to-find machine could live up to its reputation.
Image 1 of 2
(Image credit: Tom's Hardware)(Image credit: Tom's Hardware)The Saturn printed every single part on the build platform without any defects, and I was genuinely surprised and impressed with how easily the Saturn could handle a large and complex build like this. The Elegoo Water Washable resin created a support structure that was easily removed and left minimal pockmarks on the finished model.
(Image credit: Tom's Hardware)After a rinse and cure in the Elegoo Mercury Plus Cure/Wash station, I laid out the parts and assembled the model using DAP RapidFuse CA glue, a favorite of mine for making strong bonds on resin prints like this one.
The final result is a finely-detailed print that measures nine inches wide and six and a half inches tall, and it is one of the largest resin MSLA prints I’ve ever made. The 3D model to 3D print process was seamless and easy, and this model earned the Saturn a permanent place on my personal list of all-time favorite 3D printers.
Image 1 of 2
(Image credit: Tom's Hardware)(Image credit: Tom's Hardware)Printing Multiple Miniatures Simultaneously on the Elegoo Saturn
(Image credit: Tom's Hardware)One of the key abilities of a large build volume resin MSLA 3D printer like the Elegoo Saturn is the ability to print multiple parts simultaneously. The Saturn is a popular printer for users interested in tabletop gaming, and the large build volume is ideal for printing out multiple miniatures in a single print. Because the print speed is dictated by the number of layers and not the number of miniatures, printing a single miniature or a full build platform full of them takes the same amount of time.
As a test of the printer’s performance, I filled the build platform with some of the enemies from the Loot Studios Ghostly Odyssey release which features a mix of detailed creatures and human 32mm miniatures.
Image 1 of 2
(Image credit: Chitubox)(Image credit: Chitubox)After importing the models into Chitubox, I manually laid them out to prevent the support structure rafts from touching to reduce the overall total surface area of the bottom cross-section. Chitubox handled the slicing of this large tray without breaking a sweat, and I was easily able to fit a mix of models and bases for a total of 12 parts printing simultaneously. Chitubox gave an estimate of 3 hours and 51 minutes, which is an attractive print speed for such a large yield of parts.
The models have a support structure already generated, so after slicing all I had to do was detect and remove the islands (small, unconnected pixels that can cause floating bits of resin) and scroll through the layer view to check for any missing geometry.
This is a quick and largely-automated process made possible by the Chitubox app, which I am grateful that Elegoo has internally decided to endorse as opposed to attempting to make their own slicer app which may lack some of this functionality.
As I expected, the print was completed without incident. Because of the large number of support structures, the first hour or so of the print is just hundreds of tiny cylinders (as seen in the Chitubox preview above). Every time the build platform lifted, it sounded like a Velcro strap being removed as each of the tiny support structures delaminated from the FEP sheet with a tiny pop sound. I couldn’t decide whether the sound was reassuring or not, but in the end, I’m grateful for each pop because it meant the printer was working correctly.
(Image credit: Tom's Hardware)The support structures were easy to remove after a quick soak in hot water, and the models all felt like they had been cured enough to be solid.
In particular, the swords and wings on the smaller models were easy to free from the support structure, and I wasn’t concerned with them breaking off or shattering during the cleaning.
Image 1 of 2
(Image credit: Tom's Hardware)(Image credit: Tom's Hardware)Even on these 32mm miniatures, the details were crisp and features like the individual feathers on the harpy model resolved well and could be easily distinguished. If you’ve used a printer like the Anycubic Photon Mono or the Elegoo Mars Pro, this level of resolution (.05mm) is directly comparable with what you’re used to, so the big benefit of the Saturn is being able to increase your output without sacrificing quality.
The Elegoo Saturn is about as hard to find as a PlayStation 5 right now, and it tends to sell out immediately after each restock at Amazon and the Elegoo official store. After using it for this review, it’s clear to me why the printer is in such high demand: it’s fast, relatively inexpensive, and offers a build volume ideal for printing multiple parts simultaneously.
The Saturn regularly sells for over $700 on second-hand sites like eBay, so finding one may prove to be a challenge for the foreseeable future.
I asked Elegoo to comment on the relative scarcity of the Saturn, and they indicated a combination of high demand and rigorous quality control were to blame for the shortages.
These two printers are too hot sale, so they always sold out. In fact, we have arranged more products for Amazon every week, but it sold out when available. In addition, our company will test the machine before selling, so it costs some time.
Elegoo
The high-yield nature of the Saturn makes it ideal for printing multiple miniatures simultaneously, so there’s no doubt this printer will be a hit among hobbyists who are interested in printing custom miniatures. The large build volume also offers the ability to print large parts in a single print, something that smaller machines like the Creality LD-002R aren’t able to accomplish.
The overall trouble-free printing experience of the Saturn makes it appealing to beginners as well as more advanced users, but the $500 retail price (if you can even find it for that) might be a little high for a first printer. If you’re interested in a lower cost alternative, the Elegoo Mars Pro or the Anycubic Photon Mono both offer a similar printing experience at a lower price point.

Buyer's Guide - What to Consider When Buying a Resin 3D Printer
RGB vs. LCD Screens - Differences, Advantages/Disadvantages
earlier models.
This change is only to the benefit of manufacturers, since monochrome screens have many advantages over RGB. Although they are more expensive, they are more efficient, less energy intensive, and print faster due to shorter polymerization times.
Unless you choose an old used model, you will most likely buy a printer with a default monochrome LCD screen.
LCD Resolution - 2K, 4K, 6K
Like computer monitors and TVs, LCD resolution determines the level of pixels and detail.
Higher resolution translates into better XY resolution and lower layer height, which is a critical factor for the fine detail and precision we expect from resin printers.
You'll find 2K, 4K and even 8K resolution printers for those who want the ultimate level of detail and intricate detail in their prints.
However, the print quality of the 2K LCD is far superior to that of FDM printers, so it is more than adequate for most applications.
Build Volume
Photopolymer printers typically have a smaller build volume than more common FDM machines, so manufacturers and professionals use them to create small, intricate parts with high precision.
If you need extra space to print duplicate parts or large figures and models, look to larger format resin printers such as the Peopoly Phenom and Phrozen Sonic Mighty 4K.
Post-Processing Equipment
Resin 3D printing is a messy business and post-processing is a major part of the printing process.
Post-processing consists of two parts - washing and polymerization.
Flushing involves removing uncured resin residue from the print with isopropanol.
Polymerization uses additional UV light to complete the polymerization process to improve the finish and overall rigidity of the part.
Do-it-yourself, hands-on processing is one option, but manufacturers now offer versatile wash and curing stations that eliminate many of the hassles associated with this process.
How does a photopolymer 3D printer work?
Each type of resin 3D printing technology cures UV resin, they just differ in how they do it.
Stereolithography (SLA) was the first additive manufacturing technology invented, with patents granted to 3D Systems back in 1986. SLA printing works by using an ultraviolet laser and mirrors (called galvanometers) to selectively cure the resin.
DLP 3D printing was pioneered by EnvisionTEC and uses a projector similar to a movie theater projector.
LCD printing uses an LCD screen with individual LEDs that turn on and off to selectively cure specific areas of the resin to form the final object. LCDs are sometimes referred to as MSLA (masked SLA), as in Prusa and Peopoly resin printers.
Resin 3D Printing Technologies
SLA
Using mirrors, also called galvanometers, an SLA or stereolithography printer directs a UV laser beam at photopolymer liquid resin in cross sections to cure or print layer by layer.
DLP
DLP, or Digital Light Processing, is very similar to the SLA machine and involves emitting digital light (LED in most printers) through an array of micromirrors onto a light-sensitive liquid resin for flash, or in other words, curing the entire image layer at a time in so-called voxels - rectangles that look like pixels.
MSLA/LCD
Like DLP machines, MSLA or stereolithography (often referred to as LCD) printers use a digital light source (usually hundreds of LEDs) to flash an entire layer at once.
Unlike DLP, the MSLA printer uses the LCD as a "mask", directing and illuminating a photosensitive liquid resin rather than mirrors. The mask allows the printer to expose only those areas that need to be cured to the light source.
LFS
LFS or Low Force Stereolithography is Formlabs patented pot polymerization technology. LFS overhauls the standard SLA process using a custom-designed Closed Light Processing Unit (LPU) that passes a UV laser beam through a spatial filter and an array of mirrors to polymerize the photosensitive liquid resin cross-section layer by layer.
DLS
Another patented technology from Carbon 3D, DLS, or Digital Light Synthesis, uses an oxygen permeable window to cure a photosensitive liquid resin in what is known as continuous liquid interface manufacturing (CLIP). Light from a special LED engine illuminates ultraviolet rays to match the shape and details of the part's cross-section onto an ultra-thin resin layer supported by an oxygen window known as the "dead zone".
The resin in the "dead zone" is then cured to create precise, detail-rich layers.
How much does a photopolymer 3D printer cost?
Good cheap photopolymer 3D printers start at around $200. Even ten years ago, resin printers cost thousands of dollars, but with great advancement - mainly in the field of LCD printing - the prices have come down!
However, these budget photoresin 3D printers can't compete with more professional high resolution printers like the Form 3 ($3,499) or the Peopoly Phenom (1 9$99). They can still produce accurate models, for example for miniatures and other fun projects, but as a photopolymer 3D printer for business, they may not be effective.
Photopolymer 3D printer applications
Budget photopolymer 3D printers are commonly used by hobbyists to produce precise figurines and miniatures in detail that FDM printers simply cannot match. They are commonly used for 28mm miniatures, D&D figurines and other similar desktop model projects.
However, these inexpensive options can sometimes be used to create wax molds for casting jewelry. However, for higher quality precious metal casting, it is recommended to use a more professional resin 3D printer capable of better resolution and precision.
photopolymer printers are widely used in dentistry, audiology, jewelry and medical industries. For example, in dentistry, photopolymer 3D printers can print orthodontic models and implants, and in audiology, almost 100% of custom-made hearing aids are now 3D printed.
3D resin versus filament (FDM)
Hobbyists usually turn to resin 3D printing when they want higher precision, smoother surfaces and sharper details on small prints such as figurines or miniatures. While FDM is simpler, it cannot achieve these levels of precision and smoothness.
However, the trade-off between FDM and resin is that in terms of filament to resin ratio, filaments are cheaper, easier to use and reuse, come in more materials, colors and types, and tend to be stiffer.
Resins tend to be more expensive (although LCD resins are much cheaper now) and harder to use. They require thorough rinsing and post-processing, and extra care must be taken when printing and during post-processing with a resin 3D printer, including wearing protective gear, as the materials can be corrosive.
Thus, resin and thread are used for different purposes, and are not in direct competition for the same use. For the unrivaled precision of cheap 3D printers, as well as the rapid production of dental, jewelry and medical models, resin 3D printers are the way to go. But for more complex - perhaps with multiple colors - basic prototypes, deposition modeling is best suited.
Anti-selective laser sintering (SLS) resin 3D printing
The trade-off between SLA and selective laser sintering is similar: SLS-printed parts are more rigid, with excellent mechanical properties (and make excellent functional prototypes), although parts printed SLA are characterized by a smoother surface and faster printing.
SLS is also great if you're not a fan of additional support structures and don't like post-processing, because the parts printed in the resin powder chamber don't move or deform during printing. SLS offers better material properties than SLA - for example, it is not as susceptible to UV or sun damage. But they are less affordable—even the cheapest printers start at $5,000.
FAQ
Is resin more durable than PLA?
In general, conventional resin produces brittle, brittle parts that are less resistant to stress and weather than traditional 3D printing materials such as PLA. Therefore, we cannot recommend the resin for making load-bearing, functional, impact-resistant or exterior parts where PLA and ABS work much better, so manufacturers prefer the resin for fragile decorative parts filled with precise detail and a smooth finish.
Increasingly, however, 3D printing media manufacturers are offering "tough" resins such as Formlabs Tough 2000 Resin, which offer superior tear strength and even outperform ABS in some cases.
Real world applications in orthopedics (such as splints and braces) and dentistry (aligners and crowns) demonstrate how people are increasingly turning to tough resins to make strong, wear-resistant parts.
Is 3D printer resin expensive?
When viewed in the context of 3D printing and compared to other popular materials and filament types, resin is not particularly expensive. A 1 liter bottle of standard resin costs between $20 and $50 depending on the brand, which is more or less the price of ABS and PLA raw materials.
The number and size of prints you can make from a standard 1 liter bottle can vary, with costs skyrocketing for the most prolific producers.
Is the resin print dirty?
While the resin printing process itself isn't messy, post-processing of the finished print is invariably an annoying, sloppy mess, not to mention a potentially dangerous mess of dripping resin and harsh isopropanol.
This is not for the faint of heart and not for those who are afraid to get involved in this matter.
Luckily, curing and cleaning stations help keep resin processing messy, so you don't get your hands dirty by smearing prints in a vat of isopropanol.
Do resin prints need to be rinsed and cured?
Yes. The resin printing process leaves uncured resin residue on the finished part. Washing off excess resin ensures that all the details and finish of the print remain accurate when you move on to the polymerization process. It's also a safety issue: washing the resin prints removes potentially toxic, uncured liquid resin, allowing the part to be handled safely.
Curing is an equally important part of the process. When the printer has finished printing the part, the resin is in a transitional state: it is hard enough to retain the desired shape and detail, but lacks overall rigidity, making it prone to scratches, scarring, and imperfections.
Curing the print with UV, or even sunlight if you have time, allows you to reach the optimal, finished resin state.
Top 5 Resin 3D Printers (2021 Review)
Resin 3D printer produces highly reliable prints using SLA, LCD or DLP technology. It cures UV resin and turns liquid into high quality 3D models at a faster rate.
To go into more detail, stereolithography (SLA) is the earliest form of resin 3D printing, which works by adding a light sensitive liquid resin substrate to a UV laser beam. The resin is then cured to the desired pattern and the product is formed layer by layer to completion.
On the other hand, when we talk about digital light processing (DLP), we mean the process of projecting one image in each layer with a digital projector by emitting UV radiation. And with the advent of LCD technology, resin 3D printing with LCD screen is becoming predominant in the 3D printing industry today. Since the LCD screen acts as a mask over the UV light source, it is sometimes referred to as MSLA (masked stereolithography).
Having said that, getting the right resin 3D printer has never been easier with so many brands and models available on the market. So, to help you on your buying journey, we've provided the top five resin 3D printers, along with advice from our technical experts and 3D printer enthusiasts, to give you the most important information before you buy.

- Features a full color touch screen interface, real-time display and print status monitoring, fast bed leveling, strong steel body, strong adhesion, and a temperature warning system for greater safety.
Cons:
- We are a little limited in the printing area because it is a little small.
Final take:
This Longer Orange 3 Resin SLA 10D printer is one of the most iconic SLA 3D printers available and is a great entry level LCD light curing device.
Assembly takes minimal time as we were able to start printing within minutes of unboxing and the entire process took only 15 minutes. The self-developed slicing program is incredibly easy to use and very fast. We printed 28mm high mock-ups which took about 3 hours to complete. One thing to note when printing with resin is that the printing process is proportional to the height of the model, meaning that it takes the same amount of time to print six models as it takes to print one model. It produces highly accurate prints and can print complex models such as miniatures including accessories. Ultimately, there is no doubt about its effectiveness, because it produces quality products of an exceptionally high level! This Longer Orange 3 Resin SLA 10D printer is a great buy when it comes to 3D printing.
Cons:
- The manual is useless because there doesn't seem to be any cleaning or post-processing procedures, and even all the instructions are written in Chinese.
