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™.

3DXTech Recommended Print Settings for Non-Markforged Printers:

• Extruder: 265-285°C
• Bed Temp: 90-110°C
• Nozzle: We currently recommend a hardened steel nozzle
• Bed Prep: Magigoo Bed Prep and 3DXTECH Polyimide Tape gives us the best results
• Heated Chamber: Recommended

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
