Significant progress this week on all three subsystems/subteams: mechanical, electrical, and materials.

First, on the mechanical side- Caylynne and Brittney have been focusing on the extrusion module with focus on choosing optimal Nema motors for best extrusion performance. With three new motors ordered, they will be testing these motors with different step sizes and food materials to down-select on final motors. Two designs of the module are shown below, with the non-captive assembly being the stronger candidate at this time.

Ian has been taking lead in the nozzle printhead design. A 3D printed prototype has been submitted and should be ready for testing soon! Ian is focusing on a 3tube-to-3nozzle design, while Brittney has started to explore a 3tube-to-1nozzle design.

Andrew has been working hard on the electrical side to test our PID controller with the TEC, and moving forward- he and Ian will be focusing on our new Octopus Pro board integration with motor and temperature control capabilities!

Last but certainly not least, Lucas and Liying on our Materials subteam has been working hard on Instron testing and initial food material testing. More results and updates to come!
