MoldLab

Upload a part. Download a mold.

AI mold design — MoldLab reads your CAD geometry and generates production-ready tooling: printed molds, silicone kits, CNC plates, or composite layups. No mold-design experience, no mold shop. Free for Flovv owners. Everyone else: 3 molds free, then $30/month.

MoldLab designs the mold. Flovv handles the resin.

Print the tooling, then meter and mix two-part resin into it — MoldLab is included free with every Flovv.
