Rapid urethane casting prototyping
Urethane casting is a versatile and cost-effective manufacturing process. Cast urethane molds may be prepped in a matter of weeks, allowing manufacturers to create precision prototypes and move projects forward as quickly as possible. Urethane casting is also useful for bridge tooling, expediting the transition from prototyping to full production.
Manufacturing cast urethane prototypes with Fast Radius is easy: upload your CAD file to our Cloud Manufacturing Platform™ work with our engineers to make any necessary adjustments, and then greenlight production for delivery on-demand.

Why prototype with urethane casting?
The urethane casting process offers unique prototyping benefits:
Turnaround times
The speed of the urethane casting process means that you can create prototypes quickly, with lead times as low as 7 days for first articles, and 2 weeks for remaining parts.
Virtual iteration
Iterate your urethane casting prototypes virtually on our Cloud Manufacturing Platform™ and work with Fast Radius engineers to optimize your design.
Customization
Design cast urethane prototype parts with complex geometries and detail. Finish your prototypes with a range of surface textures to suit their end-use and functionality.
Ease of alteration
The versatility of the urethane casting process means that you can implement alterations to prototype parts quickly, with minimal tooling and labor requirements relative to the injection molding process..
Urethane casting applications
Consumer testing
Cast urethane prototypes are used widely for consumer testing purposes, enabling manufacturers to explore varieties of size, strength, material, and color quickly and cost-effectively.
Bridge tooling
The flexibility of the urethane casting process makes it useful for bridge tooling between the prototyping and production stages of the manufacturing process.
Joints casting
Urethane casting is ideal for creating prototypes of strong, durable mechanical joints with overlapping features.
Logos
The precision and consistency of urethane casting makes it particularly effective in the production of prototypes for 3D logos and letters.
