Objective
To create an open source pellet extruder for an open source desktop 3D Printer.
Background
Problem Statement
Project Significance
This tool head once complete will be the first Lulzbot compatible FPF-style extruder assembly.
Project Goals:
- Design a tool head that can be used on a Lulzbot Taz 6
- Design uses components found on a standard Taz 6 tool head
- Cost of toolhead less than $400
Future Goals:
- Tool head design adopted to other open source desktop 3D Printers
