Customers are increasingly asking us whether our Onyx printing material is compatible with water, diesel, oil, and acids. Today, we can provide a precise answer.

There's no other carbon fiber-reinforced printing material as popular as the Onyx printing material developed by Markforged. It has a smooth, glossy surface and excellent aesthetics, although this is secondary in harsh applications. Perhaps Onyx's best feature is that it's an extremely strong plastic.

The stability is achieved through the 80-110 µm long and approximately 7 µm thick carbon fiber pieces. The carbon fiber content is approximately 11-15%. As of today, we are able to publish a chemical material resistance list, which highlights another special feature of the Onyx printing material. It is highly resistant to many chemicals.
