What this video covers
To manufacture replacement windows for an Antares Yachts 44, the project involves thermoforming 10mm acrylic sheets over custom-made plaster molds. The process begins by using an EinScan Vega 3D scanner to capture the curvature of existing boat windows.▶ 1:02 To ensure accurate data capture on the smooth, reflective acrylic, the surface is coated with 3D scanning spray and marked with 12mm tracking dots.▶ 15:56 The resulting point cloud is converted into a 3D mesh for CAD modeling.▶ 16:37 For the molds, a CNC machine cuts a plug from MDF, which is then sealed with TotalBoat High Performance Epoxy and coated with wax.▶ 3:55 Plaster of Paris is poured into the plug to create the final mold, with some tests incorporating 3% chopped fiberglass strands for added strength.▶ 5:33 To optimize heat distribution during the thermoforming process, a four-channel data logger monitors temperatures inside and above the plaster molds while they dry in a 6000-watt DIY electric oven.▶ 14:47 The project also includes installing an Airlock 1 air purification system to manage cabin odors.▶ 9:10
