Here you can see the cross section of a 3D printed component with a classic honeycomb structure with the Markforged Mark Two. At the edge of the component there is a white “line”. This white “line” is a glass fiber reinforcement! This is additionally printed as a continuous fiber into the component via a second nozzle in the print head to achieve even greater stiffness. The continuous fiber can be inserted individually per print layer – “all over the surface”, at the edge or only at some points. This makes the Markforged 3D printers so unique! Even the base material ONYX is 23x stronger than printed ABS!

The diagram on the right shows the individual plastics in comparison with aluminium.

The Eiger Software in the background

Continuous Filament Fabrication (CFF) is a patented technology that enables Markforged users to produce 3D printed components with extreme stability. With this technology, this “continuous fiber” is additionally printed into the component via a second nozzle in the print head. It is called continuous fiber because it has only one start and one end point per layer. This allows you to achieve stability above milled aluminium in an excellent quality!

Thanks to the supplied and optimally adjusted software EIGER, you can insert the continuous fiber per layer individually and, of course, also “over the entire surface”. Carbon, Kevlar, glass fiber and high temperature glass fiber are available as continuous fiber reinforcement.
