Important Onyx Information

The X3 Composite 3D Printer™ uses a specially tuned Nylon PA6 copolymer with a chopped carbon blend as the base-plastic for the Fused Filament Fabrication (FFF) printing process. While Onyx is an amazingly tough engineering plastic and works very well with our Continuous Filament Fabrication (CFF) fiber materials, it is very susceptible to absorbing moisture. Onyx that has absorbed too much moisture will cause a number of printing issues, such as failed prints, under-extrusion, holes in the roof of parts, etc. Please take special care to NEVER leave Onyx exposed to ambient air, and ALWAYS keep Onyx in the provided Dry Box.


Tips to avoid ruining Onyx:

    • NEVER leave a Onyx spool exposed to ambient atmosphere.
    • DO NOT open a Onyx spool bag until you are ready to use it.
    • Make sure your Dry Box is FULLY Latched and Closed.
    • DO NOT open the Dry Box unless absolutely necessary. If the Dry Box must be opened, make sure to minimize the exposure time.
    • If you are planning on leaving your X3 / material unused for an extended period of time, just keep the spool in the Dry Box with the filament loaded in the printer. The Dry Box & desiccant do a good job protecting from moisture, and Dry Box-stored Onyx should last up to a year before the water content is too high for printing. When re-starting a machine after a long idle period, run the Wet Plastic Purge Print utility until it stops steaming (which may take 2-3 runs).
    • If you are planning to travel with your printer, unload the Onyx, remove the PFTE tube from the Dry Box, and use the provided Red Plug to seal the container.
  • Inspect Onyx spool bag for any holes or tears prior to using.
  • It should NOT be necessary to add more than the two desiccant pouches to the dry box. Be sure to throw older desiccant packs away when changing spools, as they will likely introduce moisture into the dry box environment, rather than removing it.
