Nylon FX256 is a high-tech material that retains its excellent functional properties under a wide range of temperatures. Perfect for the most resistant prints.

It exhibits very high interlayer adhesion while flexible in a thin layer. Its low friction coefficient and high-temperature resistance make it an excellent choice for printing functional and technical parts. It's a durable material that resists a wide range of chemicals, including car fluids.

    A good material but....

    I've purchased and used quite a bit of this material in my small business over the last twelve months, sourcing both locally and, when those supplies ran out, directly from Fillamentum. I have found it an excellent material from both the ease of print perspective and the robustness of the finished parts. They are very tough. I very much want to continue to use this material but, disappointingly, I can't get a straight answer from Fillamentum regarding it's ongoing supply. This is very frustrating and a disappointing response from Fillamentum.
