Carbon’s EPU 40 elastomeric polyurethane material is a high-performance elastomer that offers excellent elastic recovery, tear resistance, and high impact strength. It is specifically formulated for 3D printing, making it an ideal material for producing durable and flexible parts, such as gaskets and seals. The EPU 40 material has unique properties that make it suitable for various applications, including automotive, industrial, and medical devices. Additionally, this material is resistant to multiple chemicals and environmental factors, which can help extend the life of components made from it. With its high-performance characteristics and versatility, Carbon’s EPU 40 elastomeric polyurethane material is an excellent choice for those looking to produce challenging, durable, and reliable parts.
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.
