2nd Prototype Test of Injection System

Result: Leakage issue due to low resolution 3D printing of chamber and shaft

Injection System is coupled to a 12V DC motor, which is controlled with an Arduino Uno

1st Prototype Test of Injection System

Result: Dragon Skin was unable to flow through the chamber due to the tight spirals on the mixer

First Concept Design of Injection Chamber and Mixer

Material Testing with Dragon Skin: Mimic the 3D printing process by applying layers of Dragon Skin in an heated oven

Result: Higher temperature allow Dragon Skin to cure faster, resulting in more layers stacked with no drooping
