Composites are parts made up of more than one material that, when combined, have
synergistic properties different from the original materials. There are two main
components of composite parts: a matrix and a reinforcement.
Continuous Filament Fabrication (CFF) is the method with which fiber reinforced
composites are 3D printed. Continuous fibers are extruded layer-by-layer similarly to
FFF processes.
Markforged offers four reinforcement fibers: carbon fiber, fiberglass, Kevlar, and HSHT
fiberglass.
Just as carbon fiber are always laid with a matrix, so are our fibers. Our reinforcement
fibers are 3D printed with Onyx during the printing process to ensure optimal mechanical
properties, accuracy, and surface finish.
