Open source 3D printers helped launch the affordable 3D printer range we have now, starting from the RepRap movement more than a decade ago. Therefore, we ranked our favorite open source 3D printers, with links to the 3D printer source files, and where to buy them.

What is open source?

Open source encourages collaboration and the sharing of improvements with the community, leading to faster innovation and better technology for everyone. Without any IP holding people back from experimenting and improving open source 3D printer designs, fantastic new developments can occur.

  • A number of open source software feature in our best free 3D software guide.
  • Open source 3D printer software also feature in our best 3D printer software guide.

How can open source improve 3D printers?

An example of this is the development of the Olsson Block. Anders Olsson, in trying to get his Ultimaker 3D printer to print boron carbide, accidentally created a block that made switching a 3D printer’s nozzle far quicker. Now, Olsson Blocks are used by thousands of 3D printers to reduce nozzle switching time.

At the start of the consumer printing revolution, courtesy of RepRap 3D printers, open source 3D printers were the norm. Passionate makers across the world modified existing open source 3D printer designs or created their own for others to improve. They were effective yet cheap, costing just a few hundred dollars back when an equivalent 3D printer would cost thousands.

Open Source vs Closed Source 3D Printers

Makerbot, Printrbot, Lulzbot (by Aleph Objects), Ultimaker, BCN3D and several other 3D printer companies were formed championing the open source 3D printer movement. However, some have since struggled.

Printrbot closed down in July 2018 citing low sales, while Lulzbot laid off the majority of their staff in October 2019, facing closure before they were rescued and bought out. Makerbot, perhaps the most successful 3D printer company to emerge from the DIY 3D printer revolution, famously turned their back on the open source philosophy, and now their 3D printers are closed source and IP-protected. The company was acquired for $400M by Stratasys.Makerbot printers are now closed source and IP-protected.

However, some open source 3D printer companies continue to show strong growth and prove that open source is not only well-loved, but also a profitable strategy. BCN3D continue to produce high-quality printers including the Sigma D25 and Epsilon, while Ultimaker have grown to become one of the most respected 3D printer companies in the world.

We have a full list of open source 3D printers at the end of this article. First however, we have our recommendations of the best open source 3D printers with links for purchasing. We also include links to the open source 3D printer designs on GitHub.

SibRap 3D printer from the manufacturer Azbuka 3D

Construction area, mm: 185x185x150

Material for printing: ABS plastic, PLA plastic, Nylon,

All characteristics

Description of the SibRap 3D printer

SibRap - RepRap 3D printer jointly developed by PrintAndPlay and Cubekt Lab. In the new 3D printer SibRap version 1.4, the frame is laser-cut from 18 mm thick plexiglass. This increased the rigidity of the entire structure. Also, the base of the printing table is made of a 3mm thick aluminum plate with laser-perforated holes for structural elements. All these and other changes have improved the quality of printing, and also greatly simplified the assembly of the printer.

About the SibRap printer

The SibRap printer is the only 3d printer in Russia, the drawings of which are created in open source programs and distributed under open licenses (GPL). The concept of open design (open hardware), in accordance with which the project was developed, implies the free participation of everyone in the development of the project. The contribution of any participant is welcome and will be supported by the community. Buyers of the printer receive not just a printer, but a platform open to modifications, which can subsequently be improved and supplemented with new features. The current version of the SibRap printer is 1.4.

How is the SibRap 3D printer different from other printers?

  • The project is open, all drawings are available here http://wiki.livyminds.ru, everyone can contribute to the project.
  • A consequence of the openness of the project is that there is a constant process of improvement and creation of new nodes for the 3D printer.
  • The owner of the SibRap 3D printer has the opportunity to upgrade (similar to computers) his 3D printer of the previous version.
  • All repair and upgrade parts are available in Novosibirsk.
  • SibRap 3D printer, unlike many other, even more expensive printers, has a heated table, which allows you to print on it with the entire range of 3D printing materials on the world market. Without a heated bed, it would be impossible to print materials as common as ABS and as durable as nylon.
  • Ability to print materials with a diameter of 1. 75 mm and 3 mm.
  • Feeding material through a gearbox rather than directly, which increases print accuracy and minimizes the chance of overheating of the extruder motor, unlike many other printers.
  • The SibRap printer uses linear bearings rather than bushings, unlike printers from some manufacturers. This allows you to print at high speeds with great precision.
  • Also available is the SibRap 3D Printer DIY Kit, which will allow you to assemble a full-fledged 3D printer yourself for less!
  • Printer warranty - 6 months.

Marlin (Firmware)

Marlin is an open source firmware primarily designed for RepRap project based FDM (Fusion Fused Deposition Modeling) 3D printers using the Arduino platform. [1] [2] [3]

The firmware runs G-code formatted encoded commands and instruction sets as the robot software on the 3D printer control board that controls all machine actions in real time, including sending motion coordinates to stepper motors via stepper drivers, control of heating elements, sensors, lighting, bed alignment tracking, LCD displays and buttons. [4] Marlin supports many different boards and many 3D printer designs. robot platforms, including Cartesian (including Core XY), Delta and SCARA printers, and some other less traditional designs such as the Hangprinter. [2] [5]

In addition to 3D printing, Marlin is also used for many other types of machines, including SLA and SLS 3D printers, CNC routers, Laser engravers (or laser beam processing), Laser cutters, vinyl cutters, pick and place machines, and egg painting robots. [3] [6] [7]
