The new EPX 81 resin was designed for such high-precision applications in the industrial sector, and has mechanical properties similar to 20% glass-filled PBT, which is commonly used in fabrication of electrical connectors. The high-strength engineering material features top-notch abrasion resistance and a heat deflection temperature of 140°C.
In addition to EPX 81, Carbon also announced that its high temperature Cyanate Ester family was getting a new resin, CE 221. This new resin features fluid compatibility and high temperature resistance, which are only “achievable with Carbon’s patented CLIP technology.”
We have talked before with Carbon about their approach to materials and the market, as CEO and Co-Founder Dr. Joe DeSimone told us:
“Our resin diversity is what helps provide the perfect fit solution in such a wide array of verticals, including automotive, industrial design, healthcare, aerospace, and consumer electronics.”
This Ebullient processor cooling module, made with CE 221, uses the resin to route coolant in an efficient manner, while holding up under elevated temperatures, inside servers and workstations. The strong material properties of CE 221 are said to be comparable to 14% glass-filled Nylon 6, with a 230°C heat deflection. The resin is stiff, with excellent thermal stability and chemical resistancel. Just like EPX 81, it comes in 375 mL cartridges, and as it is a two-part resin, needs to be mixed. This resin is the perfect choice for applications, such as under-the-hood components and electronics assemblies, that require long-term thermal stability. The combination of Carbon’s CLIP technology and CE 221 enables parts fabricate with this resin to have precision surface finish, as well as high-temperature resistance. Take a look at the video below to see how well it holds up under high temperatures:
As of its most recent funding round, Carbon has received $222 million in funding, and is working on speeding up production for global expansion. Discuss in the Carbon forum at 3DPB.com.
