Week 4: Further Research and 3D Printed Mold Finalization (Weekly Meeting)

The team met to discuss the shapes, calculations, and material choices for the molds. We previously used PolyLactic Acid (PLA) for our 3D printed molds which had a hard and plastic-like structure but caused the hydrogel to get damaged in the removal process. We then determined that the molds can be 3D printed using Thermoplastic PolyUrethane (TPU), which is a flexible filament that can allow the hydrogel to be easily removed from the mold.
