Low-Volume Rapid Injection Molding with 3D Printed Molds

Accelerate product development, reduce costs and lead times, and bring better products to market by incorporating 3D printing and short-run injection molding into your development process. 

An Efficient and Affordable Means for Bridge Tooling

Use 3D printed injection molds with both benchtop and industrial machines to efficiently and affordably produce hundreds to thousands of functional prototypes, parts for pilot production, or end-use parts.

For Both Desktop and Industrial Molding Machines

Injection molds fabricated with Formlabs 3D printers have been tested with both desktop and industrial injection molding machines using a wide range of pressures, temperatures, and materials.
