Materials: Common plastics include ABS, polycarbonate, acrylic, and PETG, chosen for flexibility, strength, or clarity.
Mold Types: Prototypes often use cost-effective molds made from wood, resin, or aluminum, unlike production-grade molds.
Process: Involves heating the plastic sheet (typically 0.5–6 mm thick), forming it over a mold, and trimming excess material.
Advantages: Fast turnaround (days to weeks), low tooling costs compared to injection molding, and suitability for small to medium runs.
Applications: Used in industries like automotive (dashboards), medical (trays), and consumer goods (displays) for testing form, fit, and function.
Limitations: Less precise than CNC machining or 3D printing, limited to shallow or simple shapes, and not ideal for complex geometries or tight tolerances.
