A rigid, clear SLA material for functional prototypes requiring superior moisture resistance, strength, and a smooth finish.

Somos® WaterShed® XC 11122 is one of the industry's most popular materials for producing optically clear parts with the performance of durable thermoplastics. This stereolithography resin combines specified clarity and high strength, making it an ideal solution for a wide range of functional prototyping applications. Its key differentiator is its ability to produce dimensionally stable parts that offer superior moisture resistance, enabling reliable performance in fluidic or humid environments.
Parts printed with WaterShed® XC 11122 exhibit excellent clarity and a smooth surface finish directly from the printer, significantly reducing the need for post-processing. This allows for faster design validation and accelerates the product development cycle. The material’s defined mechanical properties ensure that prototypes not only look like the final product but can also withstand functional testing for applications such as packaging, duct work, and consumer electronics housings.
Engineered with low water absorption, this material ensures that part dimensions and performance remain stable even with exposure to moisture or humidity. This makes it a dependable choice for applications involving fluid dynamics, such as pump housings, manifolds, and flow visualization models, where other materials might fail.
WaterShed® XC 11122 is a versatile material that serves multiple stages of the product development lifecycle. It is ideal for creating highly detailed and durable concept models that accurately represent the final product's aesthetics. Its strength and stability also make it perfectly suited for producing functional prototypes for wind tunnel testing, RTV patterns, and investment casting patterns, providing confidence before committing to production tooling.
