For the last five years we've invested in the 3D printing world, using as many printers as we can to see what is good and what is bad. We all know that printing can be expensive — there are machines out there that start at $3,000 and go up from there — so we want you to have some idea of what you can get for cheaper. When it comes to value and quality you can't beat the Prusa i3 MK3. While it isn't the cheapest of the machines on this list, it is easily the best quality in terms of build and print.

Best Overall: Prusa i3 Mk3

In the world of hobbyist 3D printing, there are few names as well known as Josef Prusa. His work in open source 3D printing has revolutionized what can be done at home and on a budget for those who want to create amazing prints. The Prusa i3 MK3 is the latest machine based on his open source design and is easily the most advanced printer in this list.

The Prusa has automatic bed leveling, making each print start the best it can, but it also corrects the print on-the-fly if anything happens to shift the bed. With a sensor in the extruder, the Prusa can tell when you run out of filament, pause the print, and alert you to add more, saving countless mistakes in the process. From the removable bed to easily being able to remove prints without breaking them to the excellent save function, which stops your prints being lost in a power cut, the Prusa goes out of its way to make every print work.

The listing is for the kit version of the i3 mk3 so you will be required to build it yourself. Prusa does supply a fully made one but it's $200 more when you add in the extra shipping. Which one you buy will depend on your preference, but we recommend getting the kit. Plus, it's actually a lot of fun learning to build one from scratch.

Pros:

Auto bed leveling

Excellent print quality

Open source

Active community

Save functionality

Cons:

Cheaper to buy the kit

Best Value: Creality Ender 3

The Creality Ender 3 is a shining example of how a community can get together, take something cheap and flawed, and turn it into something special. The Ender 3 is not a printer for someone who wants quality prints straight of the box — you have to earn them. Sure, it's easy to get set up and it doesn't take much other to put together — just a few screws —but to get a print that you can be proud of takes effort.

The Ender 3, while being cheap, it is not configured well by Creality. The extruder setup is poor, as are a lot of the acceleration settings and because of that, it can take endless fine-tuning. Don't be dismayed though, there are people out there who are willing to help put you on track.

I never would have gotten the Ender 3 to the point of usability without the help of the Facebook and Twitter 3D printing communities, and I strongly urge you to look into those places if you intend to buy an Ender 3. Especially check out Filament Frenzy on Twitter. He can make the Ender 3 sing and dance like magic.

Of course, if you have the time to spend on it, $220 for a full-size printer that can make some fantastic prints is a bargain. If you have time to love it, it can be a great investment.

Pros:

Extremely cheap

Simple setup

Can create amazing prints

Cons:

Can take a lot of work to get right

Best For Your Desk: Monoprice Maker Mini Pro

If you are completely new to 3D printing and want something simple, reliable, and cheap, you can't do much better than Maker Mini Pro by Monoprice. The printer itself is small enough and quiet enough to sit on the desk in your office and allow you to make small, fun little projects fairly quickly. The Mini has several high-end features like Wi-Fi connectivity, along with the SD Card and direct PC connection that you normally get with larger printers.

It even comes with auto bed-leveling, which can be picky but is a great addition. There's also a heated bed for printing with multiple types of filament, something you'd expect on a more expensive printer, all wrapped in a sturdy metal body that reduces the "noise" often associated with cheaper printers. With a 4.75-inch print bed, the Mini is the smallest of the printers on this list, but if you are just starting out in 3D printing and only want to experiment, the small bed is more than enough.

With the Bowden extruder setup already a part of the Mini the results of printing are significantly better than I ever thought a $200 printer would produce. I helped my local youth room purchase three of these so the young people there can learn how to design and print in 3D and so far the only issue I have had is a blocked nozzle and an uneven print bed, both of which are the basic foibles of 3D printing and easily fixed by anybody.

Pros:

Auto bed leveling

Fits on your desk

Wi-Fi printing

Heated bed

Cons:

The print bed is really small

Best Value Delta: Monoprice Mini Delta

When I first used the Mini Delta I was ready to write it off from the start — $160 for a delta printer? It was obviously going to suck. Turns out, I was wrong. I like the Delta for a lot of reasons including its portability, it's build quality, as well as its great print quality. None of those things are as awesome as the price though. For just $160 you can have a 3D printer of your own that works as soon as you turn it on.

The interface on the Mini Delta is incredibly simple, making it perfect for youngsters and first-timers who aren't interested in taking things apart to make them work. The printer has three buttons and each one is self-explanatory, helping you get printing straight away. The nature of delta printers — delta printers use three constantly moving servo arms instead of rods and screws — means this mini model is dependable, even when being jostled. A delta, once dialed in, will give you great prints even under the worst of circumstances.

I was blown away by the print quality of this little machine and, even though it can only make really small models, it remains one of my favorites to have close by for small, quick jobs. The only issue I sometimes have is the auto-leveling is sometimes a little off and you will need to manually adjust or use a product like Magigoo to help keep it all stuck down.

Pros:

Solid as a rock

Great print quality

Simple interface

Portable

Cons:

Small

Bed leveling is janky

Best Value Resin: AnyCubic Photon

Resin printing can be expensive. The machines themselves are normally high-priced and the resins can be even pricier. Resin printing differs from the other printers on this list because it uses a liquid plastic that is cured over a UV light or shot with a laser. It can be messy, difficult, and a little dangerous so it's best to know what you want before you buy.

Somehow Anycubic made an affordable resin printer that produces some of the best quality prints I've seen from a printer under $2,000. The prints from a resin printer are gorgeous and are often impossible to tell that they are 3D printed. They often look like injected molded models.

Using Chitubox — a slicer now used by a large number of 3D printer manufacturers — to slice the models is simple and effective and makes the entire process of printing models on the Photon a breeze. One word of warning though: make sure your supports are thick in Chitubox since they can be a little wimpy if you aren't careful.

Of all the resin printers that I have owned and used the Photon is the one I recommend to friends, and therefore to you, dear readers. It's dependable and accurate every time.

Pros:

Entry level price

Almost invisible layer lines

Simple to use

Excellent slicing

Cons:

Small build plate

Chitubox can be tricky

My review of my first 3D printer, the AnyCubic Mega SE: : 3Dprinting

The AnyCubic Mega SE is my first 3D printer. I found it thanks to the Monthly Purchase Advice Megathread (Feb 2022) and thanks to /u/richie225's Generic FDM Printer Recommendations, 2022 post.

I figured I'd post this for any other first-time buyers out there. Here's what I'll cover:

1. Why I chose the AnyCubic Mega SE over, say, Elegoo Neptune 2

2. What's in the box

3. Assembly, Design, and QA Notes

4. First Impressions

5. Other items

   • Shipping

   • Firmware

Album of Images. All images linked in the below post are included in this album, and there are no extra images in the album.

TL;DR

I'm happy with the purchase. It was pretty easy to get started and the print quality appears to be good without having to do a whole bunch of calibration. I would recommend this for first-time buyers.

https://imgur.com/uumWgke.png

1. Why AnyCubic Mega SE?

My first limitation was price - I wasn't sure if I was going to like the 3D printing hobby so I wanted to minimize my (potentially wasted) investment. That narrowed things down to the AnyCubic Mega SE, the Elegoo Neptune 2, and the Kingroon KP3S 3.0 - the three least expensive options on /u/richie225's list.

I opted against the Kingroon KP3S 3.0 because of the smaller print area and the cantilever design.

The Elegoo was a little pricier and has, according to /u/richie225, a "subpar extruder". Plus it was sold out, so I went with the AnyCubic.

2. What's in the Box

Aside from the frame, PSU, and control hardware, you also get:

https://imgur.com/QUrIknv.png

• 5 Allen wrenches / hex keys (1. 5m, 2mm, 2.5mm, 3mm, 4mm)

• an 8gb micro SD card (file listing below)

• An SD and micro-SD to USB converter thing

• flush snips

• Two wrenches (~8.5mm and ~10mm)

• Mini USB-A to USB-A cable (about 6ft / 2m)

• Assembly screws

• ~30g / 10m white PLA

• Scraper

• Filament holder

All stepper motors and whatnot are pre-assembled and attached to the frame.

Assembly consists of joining the vertical XZ frame to the Y frame and connecting cables.

The Micro SD Card

These are all the files that were on the SD card. I didn't notice any malicious items but I'm always wary of external storage so I pulled the files that I wanted to keep to a secure VM and then wiped the SD card.

3. Assembly, Design, and QA Notes

Assembly

Overall assembly was pretty easy.

One of the screws that attach the vertical XZ frame to the Y frame needed re-threading, so I had to borrow a friend's tap and die set for that. I highly recommend testing all screws first before assembly.

The t-nut, which connects the aluminum frame to the control box, was a little tricky. Here's how I did it:

1. Screw the t-nut to the control panel, making sure to not tighten it fully.

2. With the control panel side of the frame over the edge of a table, tilt the control panel counterclockwise 90 degrees. It should be off the edge of the table completely.

3. Insert the t-nut into the aluminum frame.

4. Rotate the control panel 90 degrees clockwise. This should rotate the t-nut with it so that it’s in the correct orientation (long side of t-nut is vertical).

5. Slide the control panel to the proper position and insert the front screw.

6. Tighten.

The cable management could be a little better. Specifically, the Y cables can get caught on the edge of the bed as it moves to the very back, so make sure to put them under the frame instead. Also, the X cables typically sit close to the Z lead screw.

Design

A couple minor design flaws were found:

• The PSU prevents access to the back of the Z rail eccentric nuts.

• As mentioned before, cable management could be better.

• It does not have any ethernet connectivity. I would love to network this thing...

• The t-nut could have just been a standard through-hole screw.

QA

Overall QA seemed pretty good. Two items that I initially thought were QA issues turned out not to be. I've included them here so that others don't make my same mistake.

• One of the aluminum strut end caps was missing. Actually this is intentional for mounting the control panel.

• One of the rubber feet was not in the correct position. Actually this is intentional for mounting the control panel.

• There is a small chip in the PSU threading. Did not affect assembly. https://imgur.com/54KBxna.png

• The heat shrinking on the Z and Y limit sensor lines was not tight enough. Nothing a head gun can't solve though.

• The included scraper has some sharp corners that I had to file down else I'd scratch the print surface.

As I don't have any experience with 3D printing, I sadly cannot speak to more than that.

4. First Impressions

The instructions have you assemble the unit, connect cables, level the bed, run a filament test, and then print an included 3D model ("owl" by etotheipi). https://imgur.com/x4YPZvS.png

I performed nothing other than the bed leveling and extrusion test and then printed the object as a baseline. I think it turned out pretty dang well for not doing any calibration!

It printed at 190° with a bed temperature of 60°. https://imgur.com/S9rak23.png

There was a tiny bit of stringing between the owl ears and one layer had a little blob/loop, but otherwise I can't see many issues.

Other Items

Shipping

The Mega SE is not available on Amazon, so I placed my order directly. AnyCubic has the option of also adding 1kg of PLA to the order, so I did so (I wasn't aware that it would come with 30g / 10m of "starter" PLA). Total cost: $196.00 US

Shipping was very quick for the base unit (shipped to southern CA, USA). They estimated 3-8 business days, but it arrived in 3 calendar days. I placed the order on Feb 19th at 10am, received a notice that the order was on the way on the 21st at 11:30am, and received it on the 22nd at 2:30pm. It was shipped via UPS.

However, the 1kg of filament did not arrive with the printer. It was not communicated to me that it would be shipped separately - I had to contact support to find that out. They were pretty quick to reply, only taking about 4 hours for an email response. The filament is shipped via USPS and has not yet arrived.

EDIT 2022-03-05:

The filament finally arrived via USPS (2 weeks!). It's AnyCubic branded green PLA, 1.75mm. I'd say it's not worth bundling the filament in the order like I did. Save $10 and a bunch of time by finding a $20 spool on Amazon or somewhere.

Firmware

I have not yet tried updating the firmware. The control board is labeled "Mega Zero", so I assume that any firmware that works for the Mega Zero will also work for this one. If someone has already flashed the firmware for the Mega SE, please let us know how it went.

https://imgur.com/019hpyR.png

https://imgur.com/Do55ik9.png

EDIT 2022-03-05

I successfully updated the firmware using the instructions found here: https://www.th4dstudio.com/hc/downloads/unified-2-firmware/anycubic/anycubic-mega-zero-v1-v2-firmware-melzi-board/ with the following code changes:

1. In step 1. e select the board that has the heated bed:

    //#define AC_MEGA_ZERO #define AC_MEGA_ZERO_V2 

2. Also edit the X and Y steppers to use the correct TMC2208 per /u/l0vader's comment here https://www.reddit.com/r/anycubic/comments/s6tof4/anycubic_mega_se_firmware/ht84dsz/. Note that for Th4D's Unified 2 firmware, v2.42 (based off Marlin 2.0.9.3), the line numbers of these #define statements are different than what /u/l0vader has. For me, it was lines 401 and 402.

    #define X_DRIVER_TYPE TMC2208_STANDALONE #define Y_DRIVER_TYPE TMC2208_STANDALONE 

Well that's all I have to say about that.

Building a home 3D printer with your own hands: recommendations from personal experience

3D printing and assembly of 3D printers is my hobby and passion. Here I will not share detailed diagrams and drawings, there are more than enough of them on specialized resources. The main goal of this material is to tell you where to start, where to dig and how to avoid mistakes in the process of assembling a home 3D printer. Perhaps one of the readers will be inspired by applied engineering achievements.

Why do you need a 3D printer? Use cases

I first came across the idea of ​​3D printing back in the 90s when I was watching the Star Trek series. I remember how impressed I was by the moment when the heroes of the cult series printed the things they needed during their journey right on board their starship. They printed anything: from shoes to tools. I thought it would be great someday to have such a thing too. Then it all seemed something incredible. Outside the window are the gloomy 90s, and the Nokia with a monochrome screen was the pinnacle of progress, accessible only to a select few.

Years passed, everything changed. Around 2010, the first working models of 3D printers began to appear on sale. Yesterday's fantasy has become a reality. However, the cost of such solutions, to put it mildly, discouraged. But the IT industry would not be itself without an inquisitive community, where there is an active exchange of knowledge and experience and who just let them dig into the brains and giblets of new hardware and software. So, drawings and diagrams of printers began to surface more and more often on the Web. Today, the most informative and voluminous resource on the topic of assembling 3D printers is RepRap - this is a huge knowledge base that contains detailed guides for creating a wide variety of models of these machines.

I assembled the first printer about five years ago. My personal motivation to build my own device is quite prosaic and based on several factors. Firstly, there was an opportunity to try to realize the old dream of having your own device, inspired by a fantasy series. The second factor is that sometimes it was necessary to repair some household items (for example, a baby stroller, car elements, household appliances and other small things), but the necessary parts could not be found. Well, the third aspect of the application is "near-working". On the printer, I make cases for various IoT devices that I assemble at home.

Agree, it is better to place your device based on Raspberry Pi or Arduino in an aesthetically pleasing "body", which is not a shame to put in an apartment or take to the office, than to organize components, for example, in a plastic bowl for food. And yes, you can print parts to build other printers :)

There are a lot of scenarios for using 3D printers. I think everyone can find something of their own.

A complex part in terms of drawing that I printed on my printer. Yes, it's just a figurine, but it has many small elements

Ready solution vs custom assembly

When a technology has been tested, its value in the market decreases markedly. The same thing happened in the world of 3D printers. If earlier a ready-made solution cost simply sky-high money, then today acquiring such a machine is more humane for the wallet, but nevertheless not the most affordable for an enthusiast. There are a number of solutions already assembled and ready for home use on the market, their price range ranges from $500-700 (not the best options) to infinity (adequate solutions start from a price tag of about $1000). Yes, there are options for $150, but we, for understandable, I hope, reasons, will not dwell on them.

In short, there are three cases to consider a finished assembly:

• when you plan to print not much and rarely;
• when print accuracy is critical;
• you need to print molds for mass production of parts.

There are several obvious advantages to self-assembly. The first and most important is cost. Buying all the necessary components will cost you a maximum of a couple of hundred dollars. In return, you will receive a complete 3D printing solution with the quality of manufactured products acceptable for domestic needs. The second advantage is that by assembling the printer yourself, you will understand the principles of its design and operation. Believe me, this knowledge will be useful to you during the operation of even an expensive ready-made solution - any 3D printer needs to be serviced regularly, and it can be difficult to do this without understanding the basics.

The main disadvantage of assembly is the need for a large amount of time. I spent about 150 hours on my first build.

What you need to assemble the printer yourself

The most important thing here is the presence of desire. As for any special skills, then, by and large, in order to assemble your first printer, the ability to solder or write code is not critical. Of course, understanding the basics of radio electronics and basic skills in the field of mechanics (that is, "straight hands") will greatly simplify the task and reduce the amount of time that needs to be spent on assembly.

Also, to start we need a mandatory set of parts:

• Extruder is the element that is directly responsible for printing, the print head. There are many options on the market, but for a budget build, I recommend the MK8. Of the minuses: it will not be possible to print with plastics that require high temperatures, there is noticeable overheating during intensive work, which can damage the element. If the budget allows, then you can look at MK10 - all the minuses are taken into account there.
• Processor board. The familiar Arduino Mega is well suited. I didn't notice any downsides to this solution, but you can spend a couple of dollars more and get something more powerful, with a reserve for the future.
• Control board. I'm using RAMPS 1.4 which works great with the Arduino Mega. A more expensive but more reliable board is Shield, which already combines a processor board and a control board. In modern realities, I recommend paying attention to it. In addition to it, you need to purchase at least 5 microstep stepper motor controllers, for example - A4988. And it's better to have a couple of these in stock for replacement.
• Heated table. This is the part where the printed element will be located. Heating is necessary due to the fact that most plastics will not adhere to a cold surface. For example, for printing with PLA plastic, the required surface temperature of the table is 60-80°C, for ABS - 110-130°C, and for polycarbonate it will be even higher
  There are also two options for choosing a table - cheaper and more expensive. Cheaper options are essentially printed circuit boards with preheated wiring. To operate on this type of table, you will need to put borosilicate glass, which will scratch and crack during operation. Therefore, the best solution is an aluminum table.
• Stepper motors. Most models, including the i2 and i3, use NEMA 17 size motors, two for the Z axis and one each for the X and Y axes. Finished extruders usually come with their own stepper motor. It is better to take powerful motors with a current in the motor winding of 1A or more, so that there is enough power to lift the extruder and print without skipping steps at high speed.
• Basic set of plastic fasteners.
• Belt and gears to drive it.

Examples of elements appearance: 1) MK8 extruder; 2) Arduino processor board; 3) RAMPS control board; 4) motor controllers; 5) aluminum heated table; 6) NEMA 17 stepper motor; 7) a set of plastic fasteners; 8) drive gears; 9) drive belt

This is a list of items to be purchased. Hardcore users can assemble some of them themselves, but for beginners, I strongly recommend purchasing ready-made solutions.

Yes, you will also need various small things (studs, bearings, nuts, bolts, washers ...) to assemble the case. In practice, it turned out that using a standard m8 stud leads to low printing accuracy on the Z axis. I would recommend immediately replacing it with a trapezoid of the same size.

M8 trapezoid stud for Z axis, which will save you a lot of time and nerves. Available for order on all major online platforms

You also need to purchase customized plastic parts for the X axis, such as these from the MendelMax retrofit kit.

Most parts available at your local hardware store. On RepRap you can find a complete list of necessary little things with all sizes and patterns. The kit you need will depend on the choice of platform (we'll talk about platforms later).

What's the price

Before delving into some aspects of the assembly, let's figure out how much such entertainment will cost for your wallet. Below is a list of parts required for purchase with an average price.

Platform selection

The community has already developed a number of different platforms for assembling printers - the most optimal case designs and the location of the main elements, so you do not have to reinvent the wheel.

i2 and i3 are key platforms for self-assembly printer enclosures. There are also many modifications of them with various improvements, but for beginners, these two classic platforms should be considered, since they do not require special skills and fine-tuning.

Actually, illustration of platforms: 1) i2 platform; 2) i3 platform

On the plus side of i2: it has a more reliable and stable design, although it is a little more difficult to assemble; more opportunities for further customization.

The i3 variant requires more special plastic parts to be purchased separately and has a slow print speed. However, it is easier to assemble and maintain, and has a more aesthetically pleasing appearance. You will have to pay for simplicity with the quality of printed parts - the body has less stability than i2, which can affect print accuracy.

Personally, I started my experiments in assembling printers from the i2 platform. She will be discussed further.

Assembly steps, challenges and improvements

In this block, I will only touch on the key assembly steps using the i2 platform as an example. Full step by step instructions can be found here.

The general scheme of all the main components looks something like this. There is nothing particularly complicated here:

I also recommend adding a display to your design. Yes, you can easily do without this element when performing operations on a PC, but it will be much more convenient to work with the printer this way.

Understanding how all components will be connected, let's move on to the mechanical part, where we have two main elements - a frame and a coordinate machine.

Assembling the frame

Detailed frame assembly instructions are available on RepRap. Of the important nuances - you will need a set of plastic parts (I already talked about this above, but I'd better repeat it), which you can either purchase separately or ask your comrades who already have a 3D printer to print.

The frame of the i2 is quite stable thanks to its trapezoid shape.

This is how the frame looks like with parts already partially installed. For greater rigidity, I reinforced the structure with plywood sheets

Coordinate machine

An extruder is attached to this part. The stepper motors shown in the diagram above are responsible for its movement. After installation, calibration is required along all major axes.

Important - you will need to purchase (or make your own) a carriage for moving the extruder and a mount for the drive belt. Drive belt I recommend GT2.

The carriage printed by the printer from the previous picture after it has been assembled. The part already has LM8UU bearings for guides and belt mount (top)

Calibration and adjustment

So, we completed the assembly process (as I said, it took me 150 hours) - the frame was assembled, the machine was installed. Now another important step is the calibration of this very machine and extruder. Here, too, there are small subtleties.

Setting up the machine

I recommend calibrating the machine with an electronic caliper. Do not be stingy with its purchase - you will save a lot of time and nerves in the process.

The screenshot below shows the correct constants for the Marlin firmware, which must be selected in order to set the correct number of steps per unit of measure. We calculate the coefficient, multiply it, substitute it into the firmware, and then upload it to the board.
