Best Filament for the Elegoo Centauri Carbon
Elegoo's enclosed CoreXY that brought a hardened-nozzle, 320°C, fully-enclosed machine down to budget-Bambu money.
Last updated: June 2026
The Centauri Carbon was Elegoo's 2025 breakout. It's a fully enclosed CoreXY with a steel chassis and aluminum/glass shell, 256 × 256 × 256 mm of build space, and a direct-drive hotend that hits 320°C, all starting around $299. It runs fast (up to 500 mm/s, 20,000 mm/s² acceleration) and ships with a hardened steel nozzle out of the box, the spec that actually matters for filament choice. The enclosure is ventilated through a rear carbon filter rather than actively heated.
What the Elegoo Centauri Carbon prints well
Recommended materials for this printer:
Enclosed and abrasive-ready out of the box, so it handles the full range from PLA to engineering composites, no nozzle swap needed.
Since the nozzle is hardened steel from the factory, you can run carbon-fiber and glass-fiber blends (PLA-CF, PETG-CF) on day one without a nozzle swap. That's the main reason people buy this over an open bed-slinger. The passive enclosure traps enough heat for reliable ABS and ASA. What it can't do is hold a high enough chamber temperature for big polycarbonate or PC-CF parts. There's no active chamber heater, so PC tends to warp on larger footprints. The 110°C bed handles adhesion for everything up to ABS/ASA comfortably.
Elegoo Centauri Carbon specs that affect filament
This is the printer for someone who wants engineering and abrasive materials without the cost or fuss of a heated-chamber machine, and who's happy printing one color at a time. If multicolor is a hard requirement, look at the Centauri Carbon 2 Combo instead. The original's promised AMS never shipped on schedule.
Filament notes for the Elegoo Centauri Carbon
- Hardened steel nozzle ships standard, so PLA-CF, PETG-CF and glass-fiber blends print without any nozzle upgrade. This is the machine's main filament advantage over the Neptune 4 series.
- 320°C hotend covers PLA, PETG, ABS, ASA, TPU and most CF/GF composites. It sits at the edge for PC-CF and won't comfortably reach the temps some high-flow PC blends want.
- Passive enclosure (no active chamber heat) suits ABS and ASA well, since they warp far less than on an open frame, but large polycarbonate parts will still lift.
- 110°C bed is plenty for ABS/ASA adhesion. Use a glue stick or PEI-appropriate prep for the higher-temp materials.
- Dry your PETG-CF, nylon and PC before printing. The enclosure traps heat, not moisture, and these absorb water fast.
- TPU runs well thanks to the short direct-drive path. Keep speeds moderate for the softest (Shore 85A and below) flexibles.
- No active filtration beyond the rear carbon filter, so print ABS/ASA in a ventilated room despite the enclosure.
