Why Do Our Customers Love Onyx (PA6-CF) And PA12-CF?

Nylon's are very versatile polymers, with different variants and additives giving them a range of mechanical, chemical and visual properties.

Our customers request PA6-CF (Markforged Onyx) which is a chopped carbon fiber filled nylon 6, offering incredible impact resistance, chemical resistance and one of, if not the best surface finish of any of our materials. Onyx is the choice of our customers who want production quality parts, without having to spend thousands on an injection mould. We can also insert complete strands of carbon fiber, Kevlar and fiberglass in Onyx prints for insanely strong parts.

PA12-CF is our next most popular nylon, also a chopped carbon fiber filled nylon, PA12-CF offers greater mechanical performance, high heat deflection temperatures upwards of 190 degrees Celsius, less hygroscopic and also has increased layer adhesion.

PA6-GF (nylon 6 15-20% glass filled) is primarily used by our customers for part validation before moving to injection moulding.

We are also able to print in natural nylon, typically used by our customers for food safe applications.
