Silicone molding, also known as room temperature vulcanization (RTV) molding, creates finished products for prototyping, functional testing, and short-run production. PolyJet 3D printing technology is an innovative alternative to machining patterns for silicone mold making. On this edition of 30 on 3D, Peter will discuss why it’s beneficial to use PolyJet technology to create mold masters.
Instead of machining a pattern with a CNC mill, PolyJet printing can save one about 50-70% in costs and 90% of time. With its inkjet-like process, PolyJet delivers extremely high-resolution patterns with smooth surfaces. As a result, PolyJet prints are typically mold-ready and have subtle details that can be transferred to the urethane castings. Engineers can also use the 3D printed patterns to do quick functional testing, knowing they have time to iterate, allowing for more design freedom and ultimately better designs.
