Engineered for high strength and stiffness, it’s compatible with a wide range of Markforged printers, delivering industrial-grade performance with zero hassle.

## Description

Obsidian-GF Glass Fiber Reinforced PA6 filament was formulated to offer rich colorful options in an engineering-grade material for your Markforged printer. Obsidian-GF is a lower-cost drop-in Markforged Onyx Alternative suitable for all Markforged printers. 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 chopped glass fiber and PA6 copolymer, Obsidian-GF is an excellent alternative to Onyx that allows our customers choose brilliant colors, excellent mechanical properties, and save money when using your Markforged printer. Don’t have a Markforged printer? That’s no problem – Obsidian-GF is also compatible with all non-Markforged printers that are suitable for printing PA6+GF. Take advantage of the excellent strength, stiffness, and appearance of this specialty material without over spending on Markforged Onyx.
