The Prusa Mendel i3 is the third version of the open source 3D printer Prusa Mendel. Our version is based on an aluminium frame cut by water jet cutter and threaded rods. Axis motion is made on linear bearings, belts and pulleys or threaded rods and NEMA 17 motors.
The purpose of this document is to provide a visual guide needed to build a Prusa Mendel i3 3D Printer.
The machine's design files and the assembly instructions are licensed under the GPL.
Note: The Prusa i3 Rework now has a version 1.5. The documentation in this wiki is for the original version.
