mesh2mold turns any 3D model into a ready-to-print two-part mold: sealed, vented, with a pour port and alignment keys, generated in about a minute in your browser. Print the mold once, then cast parts in resin or silicone all day — the missing middle between slow repeat 3D prints and five-figure injection tooling. Configurable vents accept vacuum fittings for budget resin infusion, including forged carbon fiber. Free to try: 5 molds with full 3D preview, and your first mold download is free.
Built by Merc Industries, a working fabrication shop. Going to real injection molding instead? See Merc Mold DFM — it grades your part's moldability face-by-face and tells you in plain English what will and won't come out of a steel mold, before you pay for tooling.
