The original version underperformed on Markforged printers, so they rebuilt the formula from scratch — and now position it as a direct drop-in alternative to Onyx. The TDS includes independent lab data comparing it head-to-head against Onyx on the same machine with identical settings. Available here in black, 750 g, 1.75 mm. Also compatible with open-frame printers capable of running PA6+CF.\u003c\/p\u003e\n\u003ch3\u003eKey Specs at a Glance\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePA6 copolymer with high-modulus carbon fiber reinforcement.\u003c\/li\u003e\n\u003cli\u003eIndependently tested against Onyx on a Markforged X7 — data included in the TDS.\u003c\/li\u003e\n\u003cli\u003eHDT of 147 °C at 0.45 MPa, versus 145 °C for Onyx under the same test conditions.\u003c\/li\u003e\n\u003cli\u003eNozzle: 265–285 °C | Bed: 90–110 °C | Enclosed chamber recommended.\u003c\/li\u003e\n\u003cli\u003eHardened steel nozzle required.\u003c\/li\u003e\n\u003cli\u003eDry at 80 °C for 6 hours before printing.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eIs My Printer Compatible?\u003c\/h3\u003e\n\u003cp\u003eOn Markforged machines, this is right in its element. For open-frame printers, you'll need a hotend that reaches 285 °C, a heated bed at 90–110 °C, a hardened steel nozzle, and ideally an enclosed build chamber — 3DXTech specifically recommends a heated enclosure. If your printer has a brass nozzle and you're not planning to upgrade it, skip this filament: carbon fiber will destroy it.\u003c\/p\u003e\n\u003ch3\u003eDoes It Actually Match Onyx?\u003c\/h3\u003e\n\u003cp\u003eHere are the numbers straight from the 3DXTech TDS, tested on a Markforged X7 at 275 °C. Z-axis tensile: 23.4 MPa vs. 20.1 MPa for Onyx. XY-plane tensile: 23.8 vs. 26.1. Edge-on tensile: 31.0 vs. 31.9. Modulus is higher across all three orientations, and edge-on flexural strength also edges ahead (33.9 vs. 30.8 MPa). Unnotched Izod impact comes in slightly lower: 854 vs. 940 J\/m. Overall: very comparable performance, with a stiffness advantage.
