Somos® WaterShed XC 11122
Somos® WaterShed XC 11122 is the clear solution for designers looking for ABS and PBT-like properties for stereolithography technology. It produces highly detailed parts with superior clarity and water-resistance. As one of the industry’s most popular materials, Somos® WaterShed XC 11122 is the clear solution for numerous applications. Somos® WaterShed XC 11122 mimicks the look and feel of clear thermoplastics, such as ABS and PBT.

Somos® ProtoGen 18420
DSM’s Somos® ProtoGen 18420 is an easy-to-print, ABS-like, photopolymer that produces accurate parts ideal for general purpose applications. It offers superior chemical resistance, a wide processing latitude and excellent tolerance to a broad range of temperatures and humidity, both during and after the build.

DSM Somos NeXt Propeller

Somos® NeXt
Somos® NeXt provides the accuracy of stereolithography with the look, feel and performance of a thermoplastic. Somos® NeXt is nearly indistinguishable from finished traditional thermoplastics, but has toughness, durability and accuracy not traditionally seen in stereolithography resins. 3D printing functional testing applications and prototypes with this unique material can save significant amounts of time, money and materials.

Somos® WaterShed Black

Somos® WaterShed Black
Somos® WaterShed Black provides a solution to build rigid, tough parts, while eliminating the need for painting or coating. With similar properties and processing as Somos® WaterShed XC 11122, this multipurpose resin provides the same benefits in a black stereolithography material. Somos® WaterShed Black boasts faster processing times and eliminates the need for painting or coating - a true time and resource saver. Learn more.
