Markforged have a proprietary material called Onyx. This material is Nylon-6, blended with carbon fibre, which is about 20% stronger than ABS. Some Markforged 3d printers allow the inlaying of continuous fibres, that reinforce and strengthen the printed parts even further.
Onyx is by far the most widely used, and versatile, material at the moment. Markforged are continuing to develop and release materials that extend the applications for printers. This year we saw the release of Precise PLA, a special version of the popular PLA material for quality printing on the Markforged machines, giving users a low cost alternative for prototyping and in 8 different colours.
The Industrial Series of Markforged 3D Printers have access to specialist materials as well, such as Onyx FR and Onyx ESD, a v0 rated flame retardant and ESD compliant material respectively.
The all new FX20 has taken the Markforged portfolio into high-temperature engineering polymers, namely ULTEM™ 9085. An extremely resistant thermoplastic with excellent flame, smoke and toxicity properties (FST) widely used in aerospace and automotive.
Its important to consider what materials you will need, or may benefit from, before you buy a Markforged printer.
