Somos® WeatherX™ 100 is an environmentally durable DLP photopolymer that was developed for 3D printing functional end-use parts. It produces parts repeatedly and predictably, with the right set of performance properties that last a product’s lifetime. Tested against the most stringent SAE industry specifications, Somos WeatherX 100 demonstrates the optimized balance of weather- and chemical resistance and dimensional stability, and robust material behavior in printing and post-processing. Somos WeatherX 100 is the first DLP material that comes with reliable testing data on material weatherability, UV-testing, durability and dimensional accuracy using SAE industry standards similar to those used for thermoplastics. These tests show that Somos WeatherX 100 retains its properties better than other commercial DLP materials positioned as durable.
