Obsidian™ v2 Nylon 6+Carbon Fiber [Enhanced Markforged Onyx Alternative]

Obsidian™ v2 is the next evolution of 3DXTech’s best-selling PA6+CF engineering filament — now offering improved printability, higher strength, and greater thermal stability. Designed as a lower-cost, drop-in Markforged Onyx™ alternative, Obsidian™ v2 delivers exceptional surface finish, stiffness, and durability while maintaining outstanding ease of use.

Made using premium Nylon 6 reinforced with high-modulus carbon fiber, this updated formulation provides better layer adhesion, reduced warping, and a superior matte carbon-fiber appearance. Whether you print on a Markforged system or a high-performance open-materials printer, Obsidian™ v2 offers a professional-grade material experience without the premium cost.

No Markforged printer? No problem. Obsidian™ v2 is fully compatible with advanced open-material printers capable of handling PA6+CF, allowing you to take advantage of its impressive mechanical performance across a wide range of industrial applications.
