Most lately making AM business headlines attributable to its new M3 Collection printers and the availability of its Carbon Design Engine to non-customers, the most recent information from Carbon is its latest materials, a flame-retardant photopolymer resin referred to as EPX 86FR that makes use of the 3D printing unicorn‘s patented dual-cure course of. The brand new materials—a part of the corporate’s idea-to-production platform—options excessive power, long-term stability, practical toughness, and, after all, flame retardance; this latter property means the resin can be utilized for a number of purposes within the aerospace, automotive, shopper, and industrial markets that want UL 94 V-0 or FAR 25.853(a) scores.
The brand new EPX 86FR is suitable with Carbon’s M1, M2, M3, M3 Max, and L1 3D printing programs, and has comparable properties, similar to temperature stability and toughness, to the corporate’s high-strength EPX 82 epoxy-based engineering materials, however with the added advantages of upper inexperienced power and accuracy, and fewer warpage.
“We’re thrilled to convey this new materials to market, broadening the already spectacular supplies choices we’ve for our purchasers. EPX 86FR was created for vital industries and markets that require a V-0 flame score, excessive efficiency mechanical properties, and clean floor high quality in a dependable, constant, and excessive throughput printing platform,” Jason Rolland, Senior Vice President of Supplies at Carbon, said in a press launch.
Carbon’s new EPX 86FR resin options 5% elongation at break, 90 MPa final tensile power, and a warmth deflection temperature of 135°C, along with isotropic properties, clean floor end, and nice retention of fabric properties throughout high-temperature growing old, thermal shock, and temperature/humidity biking. The resin may also help decrease tooling prices and improvement time for manufacturing instruments, end-use elements, and practical prototypes that want self-extinguishing and flame-retardant options, like brackets, high-speed information connectors, and housings. Different purposes embrace circuit board covers, followers, cable clips, automotive battery instances, fasteners, and covers.
Moreover, this flame-retardant resin was lately used to manufacture warmth bathtub housings for extremely regulated electronics units by Astoria Pacific, which creates automated evaluation options for laboratories.
“We encountered important provide chain delays in sourcing PVC and sheet steel. We turned to Carbon’s platform and in depth materials lineup, together with EPX 86FR, to mitigate these challenges,” defined Whitney Menzel, Senior Engineer at Astoria Pacific. “Not solely did we expertise a a lot shorter manufacturing time-frame utilizing the flame-retardant resin–from 18 weeks by means of conventional strategies to 2 weeks using Carbon’s platform–however we additionally noticed important value financial savings, enhanced floor finishes, decreased weight, and each thermal and mechanical benefits.”
EPX 86FR additionally has a excessive chemical resistance, displaying little change in tensile properties, and no floor blemishes, after elements have been uncovered to chemical compounds simulating contact per USCAR-2 circumstances, and like Carbon’s different dual-cure resin supplies, can be utilized to 3D print elements with excessive repeatability, accuracy, and floor high quality.
This inflexible pattern equipment features a tow cap and battery case constituted of Carbon’s new EPX 86FR V0 flame-retardant materials with unmatched toughness, power and thermal stability.
Starting this week, Carbon’s new flame-retardant materials is on the market to ship in North America, Europe, and the UK. Should you’re concerned with testing this resin out earlier than you buy it, you’ll be able to request a free pattern equipment, pictured above, or request a 3D printed take a look at half from certainly one of Carbon’s licensed manufacturing companions.
