What it is

A workshop-based business making low-volume molds, such as silicone molds for urethane or resin casting and 3D-printed or hand-finished tooling, for short production runs and prototypes.

Your first three steps

  1. Make test molds of a few different shapes and materials to prove your quality and build a portfolio
  2. Post your work on maker communities and contact local small manufacturers and product designers
  3. Check zoning and HOA or lease rules for your garage or workshop, and set up ventilation and safe chemical storage
Who pays

Small product makers, prop and model makers, jewelry and food product brands, and engineers who need a few dozen parts, not thousands.

How it makes money

A price per mold set, often with a per-batch charge if you also cast the parts for the customer.
