Clay Composition: Research

Clay Composition: Results

Extruder

Control System: Hardware

Control System: Software & Firmware Blender: Used to create objects and export in stl file. Repetier Host: Used to slice stl file and generate G-code. Repetier or Marlin Firmware will be downloaded to Arduino to process G-code.

Assembly Assembly cannot be done until all parts are machined. The Plan: Collect all the parts Put everything together If something does not fit smoothly then make adjustments as needed Ensure all parts are secure enough to withstand movement of electrical parts Assist with attaching the electrical parts and extruder Pass assembled printer along for testing!
