M Prime One is a free 3D printer intended to be simple, low-cost and easy to build and use.

With the M Prime One, we have designed a 3D printer focusing on three main points:

  • Free design. The printer have been designed from scratch in a free 3D software: FreeCAD. All the files have been published under the less restrictive license we have found (CC BY 4.0). This way anybody can download the files, modify them and use them for their own purposes.
  • Simplicity. The design has few different parts (for example, cold bed, 4 motors, just two types of screws and one type of radial bearings) in an effort to reduce building complexity, cost and maintenance.
  • Documentation. This is still a work in progress, but the printer will be accompanied by assembly guides, firmware, slicing profiles, Q&A site...


Features

The features of the M Prime One are:

  • Printing surface: 200x150x150mm.
  • 1.75mm bowden extruder.
  • Compatible with any hotend with 12mm diameter mount.
  • Magnetic bed, easy to place and remove.
  • Auto-level system with inductive/capacitive sensor.
  • Cable management integrated in the design
  • Integrated electronics holder (compatible with RAMPS, can be adapted to any other board)
  • Optional LCD holder (compatible with Smart Controller)


How to build one

We are currently documenting the project, but the files have already been released and anybody can build the printer. You can find all the necessary files in the following links:
