What Are The Best Print Settings For Markforged Onyx Filament?

When it comes to Markforged Onyx filament, I’ve learned that the right settings can make or break your print. My go-to setup includes a nozzle temperature of 275°C and a bed at 85°C, which seems to strike the perfect balance between adhesion and ease of removal. I usually print at 0.15mm layer height—it’s a nice middle ground between detail and speed. For smaller, intricate designs, I drop it to 0.1mm, but for larger pieces, 0.2mm works fine.

Print speed is another critical factor. I keep it around 35mm/s to avoid issues like layer shifting or poor surface finish. A brim is essential for preventing warping, especially with larger prints. Cooling is minimal—just 20-30% fan speed after the first few layers. Too much cooling can cause the layers to separate, so I’m careful with that. Retraction is set to 4mm at 35mm/s, which helps reduce stringing without clogging the nozzle. These settings have consistently delivered high-quality prints for me, whether I’m working on prototypes or finished products.

Printing with Markforged Onyx filament requires a bit of fine-tuning to get the best results. I’ve experimented extensively and found that the nozzle temperature is crucial—270°C is my sweet spot, but I’ll go up to 280°C for faster prints or denser layers. The bed should be at 85°C with a layer of glue stick or PEI sheet for adhesion. Layer height matters a lot; 0.1mm gives exquisite detail, while 0.2mm is better for strength and speed.

For print speed, I keep it between 30-40mm/s for optimal quality. Faster speeds can lead to layer separation or poor surface finish. I use a brim for small parts and a raft for larger ones to prevent warping. Cooling is tricky; I start with no fan for the first three layers, then ramp up to 30% to avoid cracks. Retraction settings are also key—5mm at 40mm/s works well to prevent stringing.

Post-processing is another area where settings matter. Onyx responds well to sanding and acetone smoothing, so I always factor that into my print settings. For functional parts, I increase the infill to 40-50% and use 3-4 perimeters for extra durability. These adjustments have made a huge difference in the quality and reliability of my prints.

I've been 3D printing with Markforged Onyx filament for a while now, and I’ve found that the best print settings depend on what you’re aiming for. For general use, I stick to a nozzle temperature of around 270-280°C and a bed temperature of 80-90°C. The layer height I prefer is 0.1mm for detailed prints, but 0.2mm works just fine for stronger, functional parts. I always use a brim or raft for better adhesion, especially for larger prints. The print speed is usually set between 30-50mm/s to ensure quality without sacrificing too much time. Cooling is minimal, just around 30% fan speed after the first few layers, to prevent warping but still maintain layer adhesion. These settings have given me consistently good results, whether I’m printing prototypes or final parts.
