Materials for 3D printing

The mechanical data we publish for our materials is always from actual test results, as opposed to taken from the manufacturers’ data sheets. As well as using a number of widely used high-performance 3D print materials, we also develop composites using graphite and carbon.


Materials for selective laser sintering (SLS)

Carbon SLS – Carbon Fibre Reinforced Plastic

A specialised carbon fibre filled plastic ideal for functional components that need to be light and strong. It has the highest strength-to-weight and stiffness-to-weight ratios of any 3D printed plastic. Graphite Additive Manufacturing is the only 3D printing bureau in the UK that offers Carbon SLS.
