3D printing company Carbon, the maker of the M1 3D printer and developer of CLIP 3D printing technology, recently released three new engineering resins for its CLIP platform: EPX 81, the newest addition to Carbon’s Epoxy material family; CE 221, a high temperature Cyanate Ester material; and UMA 90, a material with enhanced toughness, ideal for manufacturing tooling, fixtures, and prototyping.

California-based Carbon, formerly known as Carbon 3D, has become known for its innovative Continuous Liquid Interface Production (CLIP) 3D printing technology, as well as its Two-Stage Cure process. The proprietary CLIP method of 3D printing involves a photo polymerization process that has achieved stunning results in terms of surface finish and isotropic properties. With its latest release, the Redwood City company is seeking to grow its selection of CLIP resin materials.

The first of the three new materials, EPX 81, is described by Carbon as its “most accurate high strength engineering material.” The resin, which has displayed mechanical properties comparable to 20% glass-filled PBT, boasts a Heat Deflection Temperature of 140 degrees Celsius, and a high abrasion resistance. Carbon says these features make the material suitable for a variety of applications in automotive, industrial, and consumer product manufacturing.

To showcase the new material, automotive company Delphi 3D printed connectors using EPX 81 (pictured above). According to Carbon, the 3D printed connector parts exceeded their injection molded counterparts in terms of wire terminal retention force performance. “This combination of accuracy and mechanical performance is only possible with EPX 81 and Carbon’s CLIP technology,” stated Carbon.

The second material, CE 221, is the newest addition to Carbon’s Cyanate Ester series of materials. Its material properties are reportedly comparable to that of glass-filled Nylon. CE 221’s high Heat Deflection Temperature of 230 degrees Celsius, as well as its rigidity, make it ideal for components that require long-term thermal stability, such as electronics assemblies, industrial products, under-the-hood parts, and the Ebullient processor cooling module pictured below.

Last but not least, Carbon’s new UMA 90 resin boasts a wide range of uses, which include—but are not limited to—manufacturing jigs, fixtures, and prototypes. The material is especially suited to making parts that require “enhanced toughness,” says the company. UMA 90, which is made from Urethane Methacrylate (a material similar to standard SLA resins), is available in a range of different colors, such as black, white, gray, cyan, magenta, and yellow. Users are also free to mix the resins for custom colors.
