Materials
BMF’s open micro 3D printing material system allows you to print with our specially formulated liquid polymers or to print with the material of your choice. Whether you use BMF's materials or choose your own, you have a variety of options available that will allow you to achieve the results you need based on your application.

GR

GR offers the best stiffness, with good impact strength and heat resistance.

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.

UTL

UTL offers high toughness and elongation for high flexibility applications.

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.
