Building a DIY 3D printer at home: 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.

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

You also need to purchase customized X-axis plastic parts, 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.
