Process
Using silicone molds cast on 3D-printed matrices, this method is ideal for manufacturing prototypes since it simulates the injection molding process. This process can be used to make rigid or flexible, opaque or transparent parts while offering various advantages:

Low-cost tooling, a more cost-effective option for low production volumes and/or large parts

Economical commercialization costs for short production runs

More creative possibilities as this process can easily reproduce complex details and can integrate thin and thick walls in the same part

Easy encapsulation of inserts and delicate components as the process uses low pressure and temperatures
Potentially reduced assembly costs and resolution of seal issues
Materials
We offer a wide range of urethane and silicone resins. Urethane resins for prototyping are selected to replicate, as much as possible, the characteristics of the thermoplastic resin that will ultimately be used for mass production. Options include resins that comply with flammability standard UL 94 V-0 and FDA requirements. We encourage you to speak to our technical advisors to make the best choice.
Tolerances
Tolerances vary depending on the resin. In general, a tolerance of ±0.015" should be provided for the first inch and ±0.003'' for each additional inch. Part geometry and wall thickness can affect tolerancing. Be sure to tell us which dimensions are the most critical.
