3D Printing with Liquid SiliconePublic

With the ongoing evolution of 3D printing, the task presented in this project offered a unique challenge to explore the mechanics of these devices and the implementation of a new printing material. The objective of this project was to design and prototype a 3D printer that fabricates parts using flexible silicone. Through iterative design, the team created a mechanically functional printer. The initial phases of design included creating CAD models and assemblies to be manufactured. These designs translated to the physical product with two main sub-assemblies: a typical 3D printer chassis with X, Y, and Z-axis motion and a dual-piston extruder, which mixes two-part curing silicone as the device’s build material. To expedite the curing process, a system was implemented to continuously distribute heated air around the end effector. In the final stages of testing and development, the team continued to refine optimal print settings to ensure quality silicone products.
