Carbon Fiber Resin Material for 3D Printing

Carbon Fiber Resin Material for 3D Printing
Cincinnati Inc. has released a new carbon fiber resin material for its SAAM (Small Area Additive Manufacturing) 3D printing system. The new material is impact resistant, lightweight and has a very high strength-to-weight ratio. Carbon fiber reinforcement makes the material stiff, durable and very low warping – and advanced inter-layer adhesion results in accurate, quality parts with good dimensions. The material’s superior surface finish makes it perfect for custom tooling applications, as well as assembly, CMM, welding and CNC fixtures.
