How To Make A 3D Printer At Home Cheap?

All of us are well aware that 3D printers have gained all the hype from the tech market and the tech media for a couple of years now, and with the buzzing of the 3D printers, people have wanted to buy them more than ever now. And seeing as though 3D printers have so many uses in industries such as the aeronautical industries, biology industries, making of prosthetics, etc.

This reason has made people want to buy 3D printers more and more now. But all of this comes at a price, and the cost is not cheap. A simple printer can also run you a few hundred dollars, which can get pretty hefty on your wallet if you are on a tight budget. So people have started to look for cheaper alternatives. One of them is that it is possible to make a 3D printer at home.

The simple answer is yes; it is, it may not be easy, and it may be highly time-consuming. Yet, toward the day’s end, if you are willing to cut down on costs and invest in a self-made 3D printer, not only will you get the maximum amount of satisfaction knowing that you made all of this yourself, but you will save money in the long run.

This article will tell you just how to make a 3D printer at home cheap and will control you bit by bit on what you need to do. For you to achieve your ultimate goal of becoming a 3D printer enthusiast and mastering the art of 3D and so let’s get started without any long wait.

DIY 3D Printers – The Benefits

Considering how much popularity the 3D printer hype has increased, it was high time before some people wanted to cheap out and make 3D printers. However, there are a few benefits to making your own.


The added benefit of making your 3D printer is that along with access to new information, you will get familiar with how a 3D printer generally works, the problems with it, how long it takes to work, how fast it prints, etc. By the end of it, you will have mastered the art of 3D printing’s ins and outs.


Another thing you learn to value from this is your patience. Yes, 3D printing is a learning experience, but it will probably take days and days of practice, and building and a lot of time spent on the parts, and a lot of maneuvering, so you will learn to appreciate all of that in between all of that patience.


Perhaps the most obvious advantage of learning how to make a 3D printer at home cheap is that it will save you on extra money spent, and you will save money in the long run too.


With building your 3D printer, you will also have the option to customize your printer however you may desire to; you can make it all sorts of different colors, choose your settings, etc.

Design Abilities

Words to the wise, you will have the ability to also print out high-quality prototypes by the time you have gone through a bit of setback and, therefore, will know your way through the process and journey of 3D printing.

3D Printer – Make Your Own

We are getting to the final segment of this article, which includes the actual process of making a 3D printer at home cheap. Therefore, as we move along, we will give you nearly step-by-step guidance on what to do, the material you will need, safety precautions, etc.

Keep in mind that making your 3D printer from scratch may take a while, so patience is vital!

First, we need to consider the parts you will need to know how to make a 3D printer at home cheap.


For the parts, the first thing you will require is an Arduino kit, which includes an A4988 driver, as well as a Mega R3 board, and a RAMP 1.4.

The next thing you will require is an extruder. This part will come in handy for pushing the plastic into the end hot nozzle.

A hot end will also come in needy. A desirable lot includes a sensor for temperature and a heater that will melt the plastic, a nozzle, and a cooling fan. All of this will come in handy for the melting of the plastic, and then it is cooling.

The next thing you will require is a PLA filament. This filament melt will be the leading plastic that will melt and then harden and result in your prototype.

The other parts you will need are a 12-volt power supply, a shaft coupler, threaded screw shaped like a trapezoid, radial, and bearing, a limit switch, wooden blocks, as well as a heated bed and acrylic sheets.

The understanding axis of the printer

There are three central axes of a 3D printer that you will make. A Y-axis, X-axis, Z-axis.

To make the Y-axis, we will follow these steps: take two acrylic sheets and make holes so the bearing can fit, attach the sheet with a plate made of wood, insert thread screw and then join the stepping motor by coupling. Next, take a pen cap and cut ends of it, insert in a syringe that has both sides cut too, and this will act as a bearing. Now insert a rod that is 8mm in diameter.

This finished is one part of the Y-axis frame, make three of these in total and attach them using a plate made of wood. Y-axis has now finished completion.

To make the X-axis, it is straightforward; you can follow the same steps as you did to make the Y-axis. Instead, you will tweak some of the changes. Change the length of the threaded screw to 200mm, and plate made of wood to be around 28mm, and your X-axis will finish creating.

Now moving onto the Z-axis making, it is still pretty simple; you will need old DVD parts for it. Taking the wooden block, you will join it to the X-axis and attach the DVD writer part to the X-axis.

Making of the bed

The next main important thing to construct is the bed, on which the 3D printing will take place. The process may seem tricky, but it is pretty simple. First, attach each screw to a wooden plate for your desired dimensions, take the sheet and attach it to the wooden plate with the help of 4 threaded screws, then the spring will connect to the bed, tighten the springs using a patellar.

Attaching of axes

The next step of making a 3D DIY printer is to attach the three axes; this will conjoin the entire printer together and bring you a little bit closer to the final product.

To attach the z-axis and the y axis to the x-axis, you will need two blocks constructed and cut out of wood. When the two wooden blocks are joined to the x-axis, you can attach the two axes using any nut or any screw, and by tightening it, it will tie it all together.

Making of extruder

The making of an extruder is straightforward, as any extrude that you need to assemble will come with the parts necessary for you to make it yourself. Following the instructions on the packet will guide you on building it step by step.

After it has finished, the next step will be to take that extruder and join it to the mainframe of the 3D printer.

Fixing of hot end with printer

Continuing, you will join the hot end, which will melt the plastic and get you ready to construct your prototype. Next, attach the z-axis to the hot end using screws and tighten them. Your hot lot has now finished attaching.

Insertion of PLA filament

The nearing ending steps of the progress will feed the PLA filament through the extruder; when the stepper motor has started, it will begin sending current and charge through the entire circuit, which will heat the filament that will in turn then melt the plastic. Finally, by ending the filament, you can manipulate the filament to make whatever shape you want.

With that, the making of your 3D printer has finished, and the last step is to hook up a 3D printing software, as well as a slicing software such as CURA, and using that, you can now print any prototype your heart may desire. Of course, all of this requires extreme patience and consumption of time, and with that, you need to take it slow and make sure that you take safety precautions.


3D printers have indeed given us a lot of benefits along with making our lives considerably more accessible, so it is pretty clear that it takes a lot of steps to do so.

As you have ventured through the journey of 3D printer making, you will have learned a lot of patience through the entire process of making the printer, and therefore now, with the help of the guide we provided, you will know how to make one now.
