Introduction to Urethane Casting

Commonly 3D Printing is best for one-off parts.  In that same breath, injection molding is best for mass manufacturing.  But what if you're not ready to make the investment in hard tooling and commit to thousands of units?  Or what if you'd like to get to market and start selling product while hard tooling for injection molding is underway?

For bridge production volumes in the dozens to thousands, urethane casting can sometimes provide an optimal solution.

The cast urethane process involves either a) 3D Printing a mold or b) 3D Printing a master pattern part, which is in turn used to create a silicone mold.  Once the mold is fabricated, two-part liquid polyurethane is poured into the negative space of the mold and placed in a heated pressure chamber to cure.  Polyurethane material options are numerous, with the ability to mimic various shore value hardness levels, and deliver a range of performance characteristics, like heat and flame resistance, or biocompatibility for medical/food applications.

Once cured, cast urethane parts can be painted or textured, resulting in a finish that is effectively identical to an injection molded part and suitable for production applications.
