Obsidian™ PA6+CF filament was formulated to be a lower-cost drop-in Markforged Onyx

1kg of Obsidian vs 750g Markforged Onyx

Alternative to ONYX suitable for all Markforged printers and DIY machines.

IMPORTANT: 3DXTech recommend to dry this filament on 1st use as it can be very hydroscopic even if new.

We developed this material after extensive analysis and testing on our own in-house Markforged printer and many outside beta testers.

The result is a seamless printing experience that produces parts with an outstanding appearance and excellent mechanical properties.

Made using premium high-modulus carbon fiber and PA6 copolymer, Obsidian™ is an excellent alternative to Onyx™ that allows our customers to save money when using your Markforged printer.

Don’t have a Markforged printer? That’s no problem – Obsidian™ is also compatible with all non-Markforged printers that are suitable for printing PA6+CF. 

Take advantage of the excellent strength, stiffness, and appearance of this specialty material without over spending on Markforged Onyx™.

Formtech's Settings for what I have tweaked for my machines ( Non MF)

  • Extruder : 280°C - I run hot and seems to work very well
  • Bed: run at 110°C- Once again stops any lift off and keeps plastic under control
  • Brim: YES, helps with warping later on 10mm brim 1st layer
  • Perimeter walls 3min and top and bottom 4 min
  • Magigoo PA ( Nylon) on clean well washed G11 bed
  • Chamber warm but not hot, ambient temp from the bed

Drying Instructions: 90°C for 4 hours if the filament exhibits signs of moisture
