Obsidian PA6+CF V2 [Markforged ONYX Alternative]

When the original Obsidian™ CF didn’t meet expectations on Markforged printers, we took your feedback seriously. We went back to the lab and reengineered the formulation from the ground up: refining the material, enhancing processability, and thoroughly testing to ensure it delivers where it counts.

Obsidian™ CF v2 has undergone extensive in-house testing and real-world validation by our user community. Customers across industries have confirmed exceptional results on Markforged® printers as well as a wide range of open-source systems. From mechanical strength and layer adhesion to surface finish and print reliability, v2 outperforms expectations across the board.

In side-by-side comparisons, Obsidian™ CF v2 is now a true one-to-one alternative to Markforged’s Onyx, but at a better value.

Obsidian™ PA6+Carbon Fiber [Markforged ONYX Alternative]

Obsidian™ PA6+CF filament was formulated to be a lower-cost drop-in Markforged Onyx Alternative suitable for all Markforged printers. This material was developed after extensive analysis and testing on Markforged printers and many 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™.

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

Drying - very important: (See our Filament Drying Kit) This product is supplied dry and sealed in thick 4mil pouch with several packs of desiccant. However, it is made using nylon and will absorb more moisture than other resins when left exposed to the environment. Excessive moisture will result in popping at the nozzle (water boiling off, a little steam) and excessive drooling and nozzle build-up. Make sure to keep this filament in a dry location between uses. If the filament does get wet, you can dry it out with a basic toaster oven (not one for the family food!). We recommend drying it for 2-3 hours at 70-80°C. Caution: Make sure to check back often to make sure you're not distorting / melting the reel - the reel itself has lower thermal resistance than the nylon filament and will distort / melt before the nylon.
