Jeff Klein says that, following months of rigorous testing, MarkForged now has final material specifications for the company's Fused Filament Fabrication and Continuous Filament Fabrication printing materials. And those results provided some pleasant surprises for the makers of the Mark One 3D printer. While the company initially thought that their Carbon Fiber CFF was up to 5x stronger and 20x stiffer than ABS, the final numbers revealed that parts made with the material are actually up to 30x stronger and 30x stiffer than similar parts printed in ABS. Documentation and test results include data on the tensile, flexural, compressive, and heat deflection temperature testing for the material line-up of carbon fiber, Kevlar, fiberglass, and nylon formulations.
