M Prime One is a free, low cost and easy to use 3D printer

M Prime One

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

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 start building an M Prime One

You can get the files and start sourcing the parts with the content that is already in this repository:

• The frame .dxf files for cutting the frame are in the frame directory. Read the README to choose one of the frame versions.
• The printed parts files for printing are in the printed_parts directory. Also, read the README files that will guide you through the process of choosing the parts to print.
• The complete part list is the Bill Of Materials, or BOM.
• Finally, until a proper assembly guide is published, you can use the assembled FreeCAD model to help you build the machine.
