DIY 3D Printer Plans

Are you ready to build the best DIY 3d printer? If you are, then check out our list below.

Get started

First, you have to decide what type of 3D printer you want to build. So, here are some questions that you need to answer to determine the printer’s specifications.

  • How do you want your DIY 3D printer to look like?
  • What capabilities do you require from your printer?
  • What size parts should it be able to manufacture?
  • Should it allow you to use multiple filaments?

Tip: The more features you want for your DIY 3D printer, the more difficult it would be to create your machine. It’s best if you start by building the most basic printer and just add more features according to your needs over time.

Collecting the DIY 3D Printer Parts

If you are using a 3D printer builder kit, all the parts needed to build the machine will be included in the kit. However, if you start from scratch, you have to be creative to get the parts you need. So, here’s what you should do.

List the parts.

Based on your answers above, research for the parts that you need for your 3D printer. There are several sites that share detailed instructions including the constituent parts for various 3D printer models.

Buy the parts

At this point, you have several options to access the parts that you need. You can visit sites that sell second-hand DIY 3d printer parts to buy those items at a much cheaper price.

Buying second-hand parts can help you save a lot while getting the same performance you expect from your printer. However, there are parts that you need to buy brand new to ensure a smoothly-functioning machine.

You can purchase used parts for DIY 3D printers here:

If you want to save more, you can also cannibalize other electronics. For instance, stepper motors can be obtained from old DVD drives while the power supply from a computer can work for 3D printers too.

If you are looking for brand new parts for your DIY 3D printer you can purchase it in the following sites:

Prepare the Software

Once your hardware is ready, you have to hook-up the printer to your computer with a 3D software. The 3D rendering software is necessary to send commands to the printer on the exact shape and dimensions of the piece that needs to be printed and to convert your 2D drawings into 3D models.

Building the Printer

Once you have collected the parts that you need to construct your printer, it’s time to start building. However, this is not a quick process. This will likely take weeks or even months.

[su_note note_color=”#F9E5E5″ text_color=”#000000″]📌I suggest that you take your time and don’t try to finish everything at once. If you rush, chances are high that you will make mistakes while assembling your DIY 3D printer. Once this happens, you will waste your resources and energy while ending up with a faulty machine.[/su_note]

If ever you encounter problems while assembling the printer, don’t be afraid to ask for help because the 3D printing community is big and the members are helpful. You can seek advice on 3D printing forums, there you will likely meet more experienced builders.

Build With Your DIY 3D Printer

Once your DIY 3D printer is ready, add the filament to the extruder. Once it’s ready, you can now test it. For beginners, you need to get your 3D model ready. If you don’t have one, no problem, there are a number of sites that offer pre-designed shapes and object files that you can use for your first 3D printing project.

You can download the files and run them through your 3D rendering software to create 3D printed parts. Just make sure that the DIY 3D printer is capable of printing out the dimensions specified in the downloaded files.

Now, it’s time to take a look at the different DIY 3D printer plans available on the market and start to build your own 3d printer kit!

Best DIY 3D Printer Kits

For the SCAD and STL files of the 3D printed components, start by downloading or cloning its GitHub repository. To do this, you can click on the link or execute the following command in your terminal or console.

git clone https://github.com/josefprusa/Prusa3.git

If you want to use the files by Josef Prusa in his workshops, you can download or clone the Prusa i3 vanilla repository. Just run this command:

git clone https://github.com/josefprusa/Prusa3-vanilla.git

Bill of Materials

The Prusa i3 Buyers Guide includes a comprehensive list of parts (nuts, bolts, rods, etc) with detailed specifications to complete your DIY 3D printer. However, you should know that there are two variants for this printer and each has a different style of frame.

The box style frame is commonly made out of plywood, has more rigid geometry and is considered to be more difficult to construct. Meanwhile, the single sheet frame is commonly made out of laser-cut aluminum. It’s more costly but more popular too.

Software and electronics

The original Prusa i3 uses a RAMBo board to control its electronics. The board is compatible with different types of firmware. However, the original Prusa i3 uses its own optimized Marlin firmware, which can also be compiled from the source.

For the firmware, visit the following repository.
