HEK
HEK is a rigid, tough material with a good combination of strength and elongation.
HTL
HTL is a high performance engineering material with high strength, rigidity, and heat resistance, able to withstand temperatures up to 114°C.
BIO
BIO is a biocompatible resin suitable for non-implantable medical applications. BIO can undergo sterilization and has passed numerous ISO biocompatibility tests.
RG
RG from the Forward AM Ultracur3D® photopolymer resin line is a durable engineering material which can be used to print functional end-use parts. In addition to being biocompatible, it doesn’t uptake any water and is suitable for a wide range of applications such as electrical cases, medical devices, snappers and functional prototyping. Only available on the microArch 200 series.
HT 200
HT 200 is a high temperature material that can withstand temperatures up to 200°C with high strength and durability, perfect for end use applications.
AL Ceramic
AL (Alumina) Ceramic is perfect for applications involving tooling, casings and housings, and medical devices – able to withstand high temperatures with high strength properties and chemical resistance. Only available on the microArch 200 series.
MT Ceramic
The combination of high dielectric constant and low dielectric loss make MT (Magnesium Titanate) Ceramic suitable for millimeter wave applications such as antennas, wave guides, and other electronic components. Only available on the microArch 200 series.
