1. How I Will Use Molding and Casting
[Placeholder — 100–150 words on how molding and casting fits a project of mine: which part I want to reproduce, why casting is the right process for it (multiples, material properties, surface finish), and what material I plan to cast in.]
2. 3D Design — Part, Negative Mold, Master Mold
[Placeholder — 100–150 words on the FreeCAD design process for the part, the silicone negative mold and the wax master mold; what I learned about draft angles, parting lines, vents and pour holes.]
[Link — molding.FCStd FreeCAD project file once uploaded.]
3. CNC Milling the Wax Master
[Placeholder — 100–150 words on booking the CNC slot via Assignment 13: CNC Scheduling, setting up roughing and finishing toolpaths, stepover and stepdown choices for jewelry wax, fixturing the wax block, and what I learned about 3-axis molding toolpaths.]
4. Silicone Negative Mold
[Placeholder — 100–150 words on the silicone chosen (food-safe vs. MoldStar), mix ratio by weight, pot life and cure time from the Technical Data Sheet, and the PPE / ventilation / skin-contact notes from the Safety Data Sheet. What I learned about degassing, pour height and avoiding bubbles.]
5. Final Cast Object
[Placeholder — 100–150 words on the casting material (chocolate / sugar / lemonade for food-safe silicone, or SmoothCast poly-urethane resin in the ATEX room for MoldStar), the TDS mix ratio and demold time, the SDS PPE and ventilation requirements, and what I learned about pouring technique, shrinkage and surface finish on the final part.]
