To create an open source pellet extruder for an open source desktop 3D Printer.

Background[edit | edit source]

Problem Statement[edit | edit source]

Project Significance[edit | edit source]

This tool head once complete will be the first Lulzbot compatible FPF-style extruder assembly.

Project Goals:

  1. Design a tool head that can be used on a Lulzbot Taz 6
    • Design uses components found on a standard Taz 6 tool head
  2. Cost of toolhead less than $400

Future Goals:

  1. Tool head design adopted to other open source desktop 3D Printers

Bill of Materials[edit | edit source]

This project is still in development and the final bill of materials has not been finalized.
