Best Dual Extruder 3D Printers and Their Benefits

When they first appeared in the market, FDM 3D printers were only able to print with one filament at a time. More sophisticated multi-color or multi-material projects used to be a real challenge, requiring serious user skills. But demand creates its own supply, and a new technology to solve the problem couldn’t but come up. Thus dual extrusion printers entered the market, breaking new grounds for customers.

This is Top 3D Shop, and in this article, we are going to dwell upon the types and peculiarities of dual extrusion, and find out how to choose a 3D printer offering this function.

Is dual extrusion worth it?

The answer to this question, like always, depends on your particular printing tasks. Generally, if you are going to print mostly single-color and single-material models with relatively simple geometries, you can get by with a single extruder device; although even in this case dual extrusion can be of some help. For more complex projects, dual extrusion 3D printers prove definitely useful, if not indispensable in some cases.

What are the benefits of a dual extruder 3D printer?

There are two main types of dual extruder 3D printers, based on the use of dependent or independent extruders. We will discuss each type in detail a bit later, and now let’s see how customers can benefit from using a dual extrusion machine.

Pros

Support structures. Virtually, the most important advantage of a dual extruder is its ability to print supports with soluble filaments. Some complex models with overhanging elements require support structures to prevent deformation while printing. With a single extruder, supports are printed with the same filament as the model, and then removed with the risk of damaging the part. Besides, some models need internal supports, which are impossible to remove after the part has been printed. Using the second extruder for printing supports with a soluble filament solves this problem.

The most common materials for support structures are PVA and HIPS. Once the part is ready, all you need to do is just submerge it in water or limonene (if HIPS is used) to completely dissolve the supports. This reduces post-processing time and eliminates the risk of damaging the part.

Multi-color printing. Dual extruder printers allow printing with two filaments simultaneously, creating dual-color parts without the need to change filaments.

Multi-material printing. The second extruder can be used not only for creating support structures, but also for printing dual-material models, combining different properties of both materials used. For example, you can print certain elements of the model with a carbon fiber-filled filament, thus strengthening the whole structure, while the rest of the part can be printed with less expensive PLA. Some 3D printers, like Creatbot D600 Pro, use two extruders for different filament types: the left extruder for printing low-temp materials, such as PLA or ABS, and the right one — equipped with a 420 °C hotend — for printing high-temp nylons, carbon fiber-filled thermoplastics, and PC.

Increased speed. The use of two extruders allows speeding up the process, compared to single extrusion printing. With an independent dual extruder you can double the production volume of your 3D printer by making two similar parts in one go, using mirror or duplication modes.

Minimized downtime. If one extruder is clogged, you do not have to stop printing immediately, but can continue with the second extruder, thus minimizing downtime and increasing the efficiency of the printing process.

Besides a great number of obvious advantages, dual extrusion has its shortcomings, though not numerous.

Cons

High price. As dual extrusion printers are more complicated mechanisms, consequently, they are more expensive than their single extruder counterparts.

Heavier weight. The dual extruder adds some weight, which can interfere with the smooth print head movement and lead to printing failures, like stringing issues. To avoid this, you have to slow down the printing speed.

Maintenance. Dual extruder printers need more frequent maintenance and more complicated calibration than devices with a single extruder. They also require a bit more preparation of the digital model, as you have to specify the printing tasks for both extruders.

How to pick a dual extruder 3D printer

There is a large variety of dual extrusion 3D printers in the market, which differ greatly in functionality and, certainly, price range. To make the best of the technology and not to pay extra, it is worth knowing which types of dual extrusion 3D printers are available in the market, and what each type is capable of.

Types of dual extruder 3D printers

Dependent dual extruder system

The dependent dual extrusion system has two variations, implying the use of one or two nozzles.

Single nozzle. Such systems are equipped with two extruders using one print head with a single nozzle. The filaments print in turn, and after each change, the remains of the previous material should be completely removed from the nozzle to avoid color blending. In order to do this, a purge block, or prime tower, is printed to extrude the remaining filament — not the best way to save on material, though.

An interesting example of such a system, although it is not a printer itself, is the Mosaic Palette 3 Pro filament splicer, allowing for continuous printing with up to 8 filaments. The device is compatible with most single-extrusion FDM printers, and allows converting them to multi-color machines. The Palette 3 Pro also helps to save on purge blocks, as they can be included in the printed model as the infill parts.

Another example of a single nozzle dual-extrusion system is the Creality CR-X Dual Color 3D printer with a large build volume and vast creative opportunities.

Dual nozzle. This type of dependent dual extrusion uses a single print head with two dependent nozzles. This type of dual extrusion is faster than that using a single nozzle setup, as you do not spend time on switching filaments. It also gives you more freedom, as you can print with different filament types, using various nozzle diameters. Printing water-soluble support structures is a great advantage of this system.

On the downside, there is a risk of oozing, which can be minimized by creating an ooze shield — a one-layer wide wall created around the printed part to catch the remaining filament on the nozzle. Another way to avoid oozing, already mentioned above, is to build a prime tower, that is a block next to the part being printed.

Independent dual extruder system

The Independent Dual Extruder system, called IDEX, is the most advanced dual extrusion technology, as it uses two print heads moving independently from each other on the X-axis (still being dependent on the Y / Z-axes). Featuring all the benefits of a dependent dual extrusion system, like multi-material or multi-color printing, IDEX provides a huge advantage, which is simultaneous printing of two copies of the same model, either in duplication or in mirror mode. The latter can be used, for example, for making two insoles for a pair of shoes in one go. This ability means that you can double the production speed, which sounds great for batch manufacturing.

As nothing is perfect, IDEX also has its drawbacks. Firstly, the second print head adds considerable weight, thus introducing the risk of Z-wobbling. Another thing with using IDEX printers is the reduced build volume when printing in single or dual extrusion modes; while duplication mode uses the entire effective build plate area. The example of this is the CraftBot Flow IDEX XL dual extrusion 3D printer. It features the total build area of 425 x 250 x 500 mm, which is reduced to 386 x 250 x 500 mm in single print head mode, and to 351 x 250 x 500 mm in dual print head mode; while duplication mode uses the whole 425 x 250 x 500 mm build area.

Dual extruder printers — buyer’s guide. Answers to FAQ

What is a dual extruder 3D printer?

A dual extruder 3D printer, as the name suggests, is equipped with two extruders, which allows the user to combine two (or sometimes more) filaments in one project. There are different types of a dual extrusion system, with the IDEX being the most powerful. Besides multi-color and multi-material printing, as well as printing soluble support structures, it features duplication and mirror modes, which can double the production volume.

Can the Ender-3 do dual extrusion?

The Creality Ender-3 is a very popular model of an affordable consumer FDM 3D printer. It is equipped with a single extruder, but there are some options allowing the user to upgrade it to the dual extrusion system. The most obvious and safe way to do it is to buy a filament splicer, or changer, that can work with most FDM 3D printers (more of that below).

Another option is to upgrade your printer with one of the DIY open-source solutions, but they usually require serious modifications that are often irreversible. So, be sure that you really need it. The most popular modifications are DIY Chimera Project, Cyclops Hot End, and some others.

Can dual extruder printers print with soluble filaments?

Yes, they can. Dual extruder printers can use one nozzle for printing the part with the main material (PLA, for example) and the other for PVA water-soluble supports. For ABS parts, HIPS (which dissolves in limonene) is often used for building support structures.

Does dual extruder print faster?

When two nozzles are used instead of one, the overall printing time shortens significantly. Moreover, with the IDEX printers, you can double the productivity of your device using duplication and mirror modes.

How many extruders can a 3D printer have?

Normally, FDM 3D printers are equipped with a single or dual extrusion system. There are a few printer models in the market featuring triple extrusion, but they are not so popular, as the dual extrusion system is complicated enough and requires more maintenance, not to mention the triple one. There are also various third-party mods allowing for three or even four-nozzle setup.

Do dual extruder printers have an enclosed build area?

The situation is pretty much the same as with single extrusion models. Most entry-level consumer devices feature an open design, which sometimes can be complemented with an optional enclosure. More expensive professional-grade printers are usually fully-enclosed. The enclosure is absolutely necessary if you plan on printing with high-performance materials.

Can you 3D print multiple objects at once?

With IDEX printers you can print two copies of the same model either in duplication or in mirror mode.

What is the average price of a dual extruder 3D printer?

With the development of 3D printing, a lot of technologies that were only used in professional printers have now become affordable for consumers. Today you can buy an entry-level dual extrusion 3D printer for less than $500.

How do you print multiple filaments?

In dual extrusion printers, you don't have to manually change filaments to print with different materials, as they are equipped with two extruders, and the switch between them happens automatically. Dependent dual-extrusion systems only allow printing with two filaments in turn, while IDEX printers can use both nozzles simultaneously, increasing the print speed.

How to make a dual extruder 3D printer?

If you already have a single extruder FDM 3D printer, you do not necessarily have to buy a dual extrusion device to give a try to multi-material printing. You can upgrade your printer with a filament splicer, like the Mosaic Palette 3 Pro, mentioned above.

Another affordable option is the 3D Chameleon automatic color changer, allowing for the use of up to four filaments in one model.

One more way to make your printer work with different filaments (up to 12!) is the SMuFF V6 — an open-source DIY smart multi-filament feeder. It may not be the choice for beginners, as it requires certain skills in configuring your printer’s firmware, but if you feel confident with that, it is definitely an option.

Dual extruder 3D printers can produce colorful and creative projects with two different filaments

Image credit: Shutterstock/Alex_Traksel

Although it's been around for a long time in the professional 3D printing world, one of the newer technologies introduced to at-home 3D printers is dual extrusion which allows users to print with two filaments at the same time, meaning you can mix colors and multiple materials—from PETG, ABS, PLA, and carbon, to metal, wood fill, and multicolor printing filaments—to produce extremely creative projects that can even be created simultaneously.

What is a Dual Extruder 3D Printer?

Dual extrusion in 3D printing refers to the art of printing using different materials, whether you choose different colors or different types of filaments with various effects, such as plastic filaments with metallic, or wooden effects.

This gives you the ability to make superior and more impressive products, and many professionals, as well as 3D printing enthusiasts, and those who own small businesses, i.e. Etsy shops selling 3D printed creations, swear by it.

Dual Extruder Printer—Buying Guide

3D printers with dual extruding capacity are, understandably, slightly pricier than single extruders, but it is a major upgrade from the single types, and there are many dual extruder 3D printers on the market at reasonable prices of around US$300-US$400. Since you’ll be spending quite a bit on this impressive piece of equipment, you want to make sure you’re buying the best one for your needs.

Types of Dual Extruder 3D Printers

Though most dual printing machines allow for multi-color printing with different materials, there are two main types of dual extruder 3D printers available:

Independent dual extruder system

IDEX printers have two print heads and two nozzles with each print head able to either mirror the other in mirror mode, duplicate items with duplication mode, or print two completely separate objects.

Dependant dual extruders

These dual extruders have two extruders that are connected and move together to create one object using two different filaments. Two spools are loaded on the 3D printer and the printer alternates using them. These printers have the key advantage of reducing printing time since more print material can be produced than with just a single print head.

Dual Extrusion Printers—Considerations

Here are some other factors to consider why trying to find the best dual extruder 3D printers for your needs.

Print bed

As with regular 3D printers, print beds in dual extruder printers come in heated or non-heated options. A 3D printer with a heated print bed is, understandably, usually more expensive than a non-heated option but a heating plate can offer better print quality by keeping the bottom layers warm and reduce the chances of your prints warping during the printing process.

Print heads

Whereas a regular 3D printer just has one print head, a dual extruder printer will have more than one print head, with either two extruders, and sometimes even three. Some dual extruder 3D printers might have just one print head but a dual nozzle that can use two separate filaments on one print. A dual nozzle is great for printing an object in several materials or colors.

Print volume

Print volume, also referred to as the printing volume or the build volume, is how big an object you can build on any given printer. For an at-home printer, projects that would need a huge build volume would likely involve a printing process that would see the object printed off in separate parts and then stuck together afterward. The average size of a 3D printer with a larger build plate would be around 300 x 300 x 400mm.

Calibration

If you’re a beginner to the world of 3D printing, a printer with automatic calibration is highly recommended. As with most aspects in 3D printing, calibrating a 3D printer has a learning curve and an automatic calibration feature can save you time and hassle and do the hard work for you.

Other factors

Another consideration you may want to keep in mind is cost. A dual extruding printer will be priced higher than a regular single head printer, plus maintenance costs will be higher, too, because there are more parts to this machine. In addition, if you’ll be working with various filaments at the same time (or even the same filament but with two extruders), factoring in higher costs for different materials is also a must.

Some machines even come with an added laser engraver feature or you could buy a compatible laser engraver to use with it. Whatever you’re after in a dual extruding 3D printer, our below list has some of the best models on the market to suit an array of styles, needs, and budgets.

What are the advantages of dual extruder 3D printer? nine0039

The main advantages of a dual extruder 3D printer include:

Better for supports: one extruder prints your material of choice, such as ABS or PLA, while the second extruder prints water-soluble supports, such as PVA filament. These supports dissolve easily in water and produce smoother prints without having to manually remove them.

Multiple Colors: Dual filament 3D printers can print multiple colors of the same filament type such as PLA for stunning multi-color details. nine0003

Multiple parts at the same time (IDEX): IDEX 3D printers such as the BCN3D Sigma D25 have two extruders that work completely separately and can print different parts at the same time.

What is the best dual extruder 3D printer?

That's why we've ranked the best dual extruder 3D printers on the market. We rated these printers for value for money, reliability, build volume, ease of use, and various other features. nine0003

Budget Dual Extruder 3D Printers (under $1,000)

A20M price: $379

Assembly volume: A10M = 220 x 220 x 260 / A20M = 255 x 255 x 255 mm.

These amazing 3D printers break the rules of the definition of "dual extruder 3D printing". To be clear, they can be loaded with two separate filaments, such as red and yellow PLA, but they will come out of the same nozzle, mixing the two colors during the printing process. Some call it dual nozzle 3D printing. nine0003

The results are amazing. Connect red, orange and yellow threads and watch your printed vase look like an exotic cocktail. The printers offer four dual 3D printing modes: single color, dual color, gradient and mixed. This provides a huge selection of print designs for such an inexpensive dual extruder 3D printer.

In terms of specifications, the A20M has a good working volume of 255 x 255 x 255 mm, while the A10M is only slightly smaller. The A20M also boasts improved stability as it is better anchored. Overall, this is an accurate (layer resolution down to 0.1 mm), interesting and inexpensive two-color 3D printer that combines colors and filaments through a single nozzle. nine0079 single nozzle geeetech a20m filament mixer.

2. BIBO 3D printer (touch laser if purchased with laser engraver)

Dual extruder 3D printer cost: $599
Assembly volume: 214 x 180 x 160

How do we get started with the BIBO eccentric printer? Well, the most important thing is that it also performs another function. It can be used as a laser engraver! The engraver can permanently carve your favorite designs on wood, as well as cut paper or felt materials - and print in 3D! nine0003

You can purchase BIBO as a 3D printer kit or pre-assembled, with or without a laser engraver. And if he performs another function, this does not mean that he cannot succeed in both. In fact, this is a very efficient multi-extruder 3D printer with a minimum layer height of 0.05 mm and stable printing in a closed working chamber.

This is a great printer, crazy and ambitious. Even the product images on Amazon showcase the machine's character and personality. We love it. nine0003

It retained a minimum resolution of 100 microns and a Teflon tube extruder for 3D printing of PLA, ABS and nylon in a closed working chamber. nine0003

However, the main change that makes this printer so profitable is undoubtedly the IDEX upgrade. In the IDEX 3D printer, the nozzles work independently, unlike the dependent, attached nozzles on the original Creator Pro, with different modes such as Mirror Mode for 3D printing multiple identical models at the same time - a big time saver, trust me.

Other quality-of-life improvements include an improved touch screen interface, as well as important nozzle updates that prevent unused nozzles from oozing out and messing up the print bed or even causing errors. You won't find a more affordable IDEX printer. nine0003

4. BCN3D Sigma D25 — IDEX 3D printer

Best Dual Extruder Upgrades

8. Mosaic Palette 2S / 2S Pro - Best Upgrades for Dual Extrusion Filament Splicer

Palette 2S Price: $599
Palette 2S Pro Price: $799

If you want to print multiple colors without a dual extruder, consider Palette as well. Instead of 3D printing with two multi-colored filaments from separate extruders, the Palette 2S and 2S Pro fuse up to four multi-colored filaments - or different materials - together during printing to create multi-color or multi-material parts. nine0003

They work by running your model through specially designed software - CANVAS for Palette - to assign different colors to different areas of your model before printing. When a particular area needs to be printed, the Palette software splices the colored filaments to print that particular area in the material or color you choose.

This makes Palette ideal for creating architectural models for construction projects, colorful desktop models of your favorite designs or D&D models, and multicolor prototyping businesses. The standard Palette 2S model includes all of these features, while the Palette 2S Pro can also splice up to 20% faster and comes with an extended 2-year warranty and replacement parts. nine0003

Palette is compatible with hundreds of 3D printers, including almost all of the most popular options. For more information, you can check your printer's compatibility here, and as for choosing between the Palette 2S and 2S Pro: The 2S Pro cuts filament 20% faster and comes with a longer warranty - so if that's important to you, spend the extra money on 2S Pro.

9. Prusa Multi Material Upgrade 2S - Prusa Upgrade Kit

Price: $299

While you can upgrade the palette for most 3D printers, Prusa printer owners can purchase a similar Multi Material Upgrade kit that allows you to print up to 5 different materials at the same time. Prusa printers are some of the best 3D printers under $1,000 and this upgrade turns your Prusa into a multi-color or multi-material 3D printer.

The

MMU2S is an improvement over the previous version of the Multi Material Upgrade Kit 2.0, key changes include a material feed sensor, buffer and a much improved overall calibration process. nine0003

The Filament Sensor goes further, checking not only for the presence of filament, but also to see if it has reached the Bondtech gears for printing. This provides much more reliable extrusion and makes filament calibration and loading easier.

The filament buffer also saves you the hassle because each of your filaments (especially if you're using all 5!) won't get tangled or tangled. Organizing and separating each filament also saves space on your desk or 3D printer table.

Q&A for Dual Extruder 3D Printers

What is a dual extruder 3D printer?

Dual extruder 3D printers have two print heads or nozzles instead of one print head like standard FDM 3D printers. Dual printing frees you from the limitations of using only one type of 3D printer filament and allows you to create multicolored parts with ease.
Dual head 3D printing improves printing with soluble supports such as HIPS and PVA and also allows multi-color parts to be printed. nine0079 Most budget dual extruder 3D printers are dual nozzle printers, meaning they have two nozzles but extrude from a single head, but we also include more advanced printers. These advanced options include IDEX 3D printers with two printheads that move completely independently for efficient and versatile printing.

What are the main types of dual extruder 3D printers?

The main types are:
1. Dependent Dual Extruder 3D Printers - Most inexpensive multi-extruder 3D printers are dependent, that is, two nozzles that extrude separate filaments are attached to one print head. They follow the same path, filling areas (such as a support or main part) in turn. nine0079 2. Dual Extruder Independent 3D Printers (IDEX 3D Printers) - IDEX extruders use two printheads independently of each other, doubling productivity when printing multiple parts at the same time.
3. Dual Extruder Printer Upgrades - These upgrade kits, such as the Palette 2S series and Prusa Multi Material Upgrade 2.0, transform a single extruder 3D printer into a printer that can print up to 5 colors at once using splicing systems and dedicated software and plans for filling 3D models. nine0079 4. Mixed color 3D printers are some of the cheapest dual extruder 3D printers, and maybe not even dual extruders. They use one printhead and one nozzle, but two filaments to mix the colors while melting. You can print models in half color, or mix colors like red and blue to create a purple tint.

Can the 3D printer be upgraded with a dual extruder?

Yes, you can. Dual extruder upgrades such as Palette 2S (compatible with most popular 3D printers) and Prusa Multi Material Upgrade 2.0 (for Prusa 3D printers) will turn your standard FDM printer into a multi-color 3D printer. nine0079 However, manually modifying a 3D printer and adding a second extruder is more difficult. There are guides for turning your 3D printer into a dual extruder 3D printer like the Ender 3, but for the less tech-savvy, we recommend avoiding this.

Should I buy a 3D printer with two extruders?

If you want to print multi-color prints at home for fun or create better quality smooth surface prototypes using dissolvable supports, a dual extruder 3D printer is worth getting. nine0079 However, if you don't need multimaterial or multicolor prints, or want to print high resolution character models that are better suited to resin 3D printing, for example, then it might not be worth it.

Which 3D printer to choose for home and hobby

A few years ago, 3D printers were bulky industrial machines, but now 3D printing is becoming more accessible for home use. When buying their first printer, many are disappointed. This may be due to the unsatisfactory quality of the resulting models or the complex setup and maintenance of the 3D printer. nine0003

In the reviews that are found on the Internet, printers are often shown after a lot of upgrades or a long selection of settings for printing. This is not at all the result that a beginner who first got acquainted with 3D printing will get.

In order not to be disappointed, before buying, you need to understand which model is suitable for your tasks. First of all, it is worth deciding what the printer will be used for. What is the main property that finished products should have? What is more important, the physical properties of the model or the ideal surface and detail? Not only the model depends on this, but also the technology by which the 3D printer will work. nine0003

Which technology to choose? FDM or LCD?

If you need to make a small detailed figurine with a perfectly smooth surface, you should pay attention to models that work on LCD technology (LCD works on a principle similar to DLP - Digital Light Processing or “digital light processing”).

LCD prints using a photopolymer resin that cures under UV light. This makes it possible to produce without deformation, even small and thin products that cannot be manufactured using FDM technology. nine0003

Resin model

Now on sale there are many photopolymer resins with different properties. A few years ago the choice was not great. Basically, finished products were not strong enough for use in functional models. Now engineering resins have begun to appear on sale. Products from them are not inferior in strength to models made using FDM technology from ABS or even nylon. nine0277
If it is necessary to produce large products with different properties, or the tasks will be very diverse, then the choice is with FDM technology. But it is important to understand that finished products will not have a perfectly smooth surface. Of course, you can polish the model, but this is additional time and labor costs.

FDM technology builds a model using molten plastic filament, which is fed from the print head. The print head (extruder) “grows” the model layer by layer on the printing table. nine0003

FDM Models

FDM technology became widespread much earlier than DLP. Thanks to this, a wide variety of 3D printers and consumables for them has appeared. You can find many decorative plastics that mimic various materials, or engineering plastics for making functional models or mock-ups.

Choosing an LCD printer

Photopolymer printers work on one of 3 technologies - DLP, LCD or SLA. nine0003

As home printers, devices based on LCD technology are usually used due to their availability and low price.

Printer design

SLA technology appeared the very first among photopolymer printers. With the help of a point-focused beam, the desired areas of the resin are gradually illuminated. This is repeated layer by layer.

How SLA 9 works0273

Since the surface of the model is perfectly smooth, SLA has become used in the jewelry and dental industries.

Pros:

Cons:

DLP technology appeared later than SLA, but it is very similar to it. The main difference is that the light source is not a focused beam, but a projector. This made it possible to illuminate the entire layer at once, which significantly accelerated the production of models. The quality of the surface was slightly inferior to SLA, but modern DLP printers, in terms of the quality of models, are almost as good as SLA technology. nine0003

How DLP works

Pros:

Faster production of models due to the illumination of the entire layer

Consumables are slightly cheaper than SLA

High surface quality (although may be inferior to SLA)

Cons:

LCD technology is the youngest of all. The DLP principle is taken as a basis, but an LCD display is used as a matrix or illumination pattern. LEDs are used as a source of UV light in LCD technology. Thanks to inexpensive components, we managed to get a simple, but high-quality and affordable photopolymer printer.

How the LCD printer works

Pros:

small cost

Cheap parts

Cons:

Low accuracy compared to SLA and DLP (for jewelers and dentists, the quality of LSD prints may not be enough, although more and more accurate models appear with the development of technology) nine0003

Possible stray light

The quality of models may decrease at the edges of the printable area (this can be corrected programmatically)

Resins that are used as a consumable for photopolymer printing can smell strongly and unpleasantly during operation. Try to use the printer in a well-ventilated area, or choose a printer with a sealed cabinet and filter. nine0003

When choosing an LCD printer, pay special attention to the rigidity and positioning accuracy of the platform along the Z axis. If there are poor quality guides along the Z axis or even a slight play, then the surface quality of the finished model may turn out to be sloppy or the model will turn out to be unevenly striped.

Rating of the best LCD 3D printers for home

Anycubic Photon Mono

This is an LCD printer with a matrix that allows you to increase the speed and accuracy of printing. Anycubic Photon Mono will be a good helper for hobbyists and modellers. nine0003
Anycubic Photon Mono SE

Anycubic Photon Mono SE has an unusual parallel light source. This minimizes distortion at the edges of the printable area. You can effectively use the entire working area of the machine and produce many small models at a time.

Phrozen Sonic Mini 4K

Model with high resolution LCD display and large print area. The monochrome display transmits UV rays better and allows you to print much faster than similar devices with a conventional display. The manufacturer claims a screen life of more than 2000 hours. Phrozen Sonic mini 4k is suitable for almost any task. nine0003
Wanhao GR1

Wanhao GR1 has high precision and large print area (140x78x200mm). The manufacturer tried to reduce distortion at the edges of the display, this allows you to make the most of the entire work area. High precision and large print area make Wanhao GR1 not only for hobby use, but also for production.

Anycubic Photon Zero

Small and very budgetary LCD device. Its resolution and small working area (total 97x54x150 mm) is enough for printing small miniatures, figurines or small engineering models. Anycubic Photon Zero is a good choice for beginners who want to get into photopolymer printing without spending a lot of money.

Choose FDM printer

If you plan to produce large and diverse functional models or experiment, a 3D printer that prints using FDM technology is an excellent choice.

First, decide on the size of the printable area and the properties that the finished model should have. After all, some materials require a closed chamber or good airflow to work. nine0079

Some printer models can be “upgraded” in the future. For example, if necessary, purchase spare parts for a closed case, put a nozzle of a different diameter, or change the thermal barrier to an all-metal one. But not all manufacturers provide for the possibility of such upgrades.

Printer design

Despite the same principle of operation, there are several different mechanics, which have their pros and cons. nine0003
Kinematics “Prusa” (Prusa)

Perhaps the most popular kinematics among home FDM devices. Mainly due to its simplicity and low cost. The main feature is the table that moves along the Y axis, while the extruder moves along the rest of the axes. Because of this, such kinematics was nicknamed “dragstol”.

Prusa kinematics

nine0311 Pros:

Cons:

Slow print speeds. A massive table with a model is forced to constantly move along the Y axis, because of this, print quality will be worse at high speeds.

Some models have design flaws (for example, insufficient frame rigidity), they can be fixed, but for this you have to be a little inventor. Or find a ready-made solution on the Internet. nine0003

This category also includes 3D printers with console kinematics. The same prusa, only halved. Because of this, the frame is less rigid, but the printer itself is more compact.

Kinematics Ultimaker

The extruder moves along the X-Y axes, and the table only along the Z axis. All motors are trying to be fixed on the body to lighten the weight of the moving mechanisms, thanks to which it is possible to achieve high print quality at high speeds. nine0003

Ultimaker kinematic diagram

Pros:

Cons:

H-BOT or Core-XY

These are 2 similar but more complex kinematics - the table moves only along the Z axis, and the extruder along the X-Y. But to move the extruder, 1 or 2 long belts and 2 stepper motors work in concert.

Example Core-XY kinematics

Pros:

High print quality

High print speeds without loss of quality.

Can be easily closed completely

Cons:

nine0311 MakerBot Kinematics

Similar to Ultimaker kinematics, but one of the motors is located on the Y or X axis carriage.

Pros:

Cons:

Delta

Deltas do not have the usual XYZ axes. There are 3 columns in the deltas, along which the carriages move, and the position of the extruder in space is calculated using a complex formula. The table is usually statically fixed to the body. nine0003

Nuances of choosing an FDM 3D printer

In addition to kinematics, when choosing a printer, it is important to take into account some design features.

One or two extruders?

Two extruders can be used for dual color printing, but most commonly the second extruder is used for solvent support printing. If you need to print complex parts with internal cavities, then you should choose a dual extruder printer. nine0003
Closed or open printer?

Printing of functional models and parts uses plastic, which usually requires a closed chamber. If you plan to print functional prototypes or various models, you should look at printers with a closed chamber.

Bowden or direct?

There are 2 types of material supply to the print head of the printer - bowden and direct. nine0003
In a bowden, the feed mechanism motor is located on the printer body. This allows you to reduce the weight of the extruder and print at higher speeds without losing quality. But because of the long tube, printing with very soft plastics can be problematic.

Bowden feed pattern

In direct feeding, the motor and feed mechanism are located on the extruder. This increases the weight of the print head, but allows you to print with any kind of plastics. nine0003

Diagram of direct feed

Heated table or not?

The heating of the table improves the adhesion of the first layer of the model. And engineering plastics cannot be printed without a heated table.

Many manufacturers add useful additional features. They do not affect the quality of the print, but save time and nerves. The most useful additional functions are the filament presence sensor and remembering the print location after a power outage. nine0003
Filament sensor.

It will automatically pause printing if the plastic runs out. When there is a little plastic left on the spool, this feature will allow you not to stand over the guard printer until the old spool runs out in order to have time to push in a new bar “on the go”.

Power outage protection.

Remembering where to print when the power goes out can save you a lot of nerves when printing large models. You won't have to worry that after a power outage, you will have to run the model again for many hours or cut and reprint a piece of the model. It is especially disappointing to throw away a complex underprinted model with supports due to a one-minute outage. nine0003

There are also many extras. features that make using the printer more comfortable. For example, automatic calibration, touch screen, Wi-Fi and others.

Rating of the best FDM 3D printers for home

Anycubic Mega Zero 2.0

Inexpensive model with Pryusha kinematics. Good for getting started with 3D printing without a big investment. Despite the low cost, Anycubic Mega Zero 2.0 has a heated table and a resume function after a power outage. Thanks to direct feed, printing with soft materials should not be difficult. nine0003
Creality3D Ender 3 Pro

A very popular device due to its low price. But despite this, the Ender 3 Pro has a heated table and a decent print area. Can be sold assembled or as a DIY kit.

Flash Forge Finder

Small home appliance intended for children or educational institutions. The Finder doesn't have a heated table, but it does have a calibration assistant, a Wi-Fi module, and other extras that make getting to know it a lot easier. All moving and heated elements are hidden as much as possible in the case so that the child cannot get burned. nine0003
Wanhao Duplicator 6 Plus

Wanhao Duplicator 6 Plus was based on Ultimaker kinematics, but instead of bowden feed, they made direct. Because of this, it will not be possible to print super fast, without quality loss, but there will be no problems with printing with soft types of plastics. There are 2 trim levels - with a closed case and without.

Flashforge Dreamer

The Dreamer is a closed body dual extruder printer with MakerBot kinematics. Thanks to this, he can cope with printing models of any complexity. Using a second extruder for soluble support, models with complex geometries can be produced. A good choice for engineers and those who like to experiment with different materials. nine0003
Flying Bear Ghost 5

Most commonly sold as a kit (assembly kit). Assembly usually does not cause any great difficulties, even for people far from electronics or mechanics. Flying Bear is equipped with a filament sensor, a function to resume printing after a power outage and Wi-Fi connectivity.

The Flying Bear makes a great first printer for the novice user who is ready to build their own printer. nine0003
Totals

In order for the printer not to become a useless toy, you should clearly understand what it is for.

For a fan of miniatures or detailed figurines, a photopolymer printer is a good choice. A small work area is more than offset by the detail that cannot be obtained using other technologies.

For an engineer or a fan of experiments, an FDM machine with a closed chamber and two extruders is well suited. This will allow you not to limit yourself in the choice of plastics and comfortably experiment with any materials. nine0003
For a beginner who has not yet decided whether he needs 3D printing, you can opt for inexpensive machines with slick kinematics. Due to their great popularity, you can find a lot of upgrades and reviews on them.
