Carbon’s UMA 90 is an additive manufacturing material in a one-part formulation. It contains a urethane methacrylate resin that possesses exceptional mechanical properties. This material is suitable for various consumer products and industrial tooling applications. The resin is specifically designed to create smooth surface finishes, high-resolution prints, and robust parts that can endure high levels of stress and strain. It is an ideal material for producing parts requiring high strength and elasticity. The Carbon UMA 90 resin is compatible with Carbon’s advanced Digital Light Synthesis (DLS) technology, making it possible to produce precise 3D prints quickly. The material has a high glass transition temperature and retains its properties at elevated temperatures. The one-part formulation helps to reduce waste and streamline the printing process, making it more efficient and accessible to manufacture high-quality parts.

About Digital Light Processing
Digital Light Processing (DLP) is a type of 3D printing that employs a UV-sensitive liquid resin cured through a digital light projector. Once the printing process is finished, our AM technicians thoroughly clean the part, remove any supports, and apply UV and thermal curing, if necessary.
DLP 3D printing is an ideal choice for projects that require high levels of detail and finishing in various production-grade materials. This technology can produce components with varying durometers and characteristics, ranging from supple silicone to rigid high-temp cyanate ester. It is beneficial for creating small end-use components, lightweight metal part replacements, functional, high-detail prototypes, jigs, and fixtures.
