Bambu Lab P1S vs Elegoo Centauri Carbon
- Build volume is effectively the same on both, near 16.8 L.
- Per litre, the Centauri Carbon is the cheaper space at $18 against $24.
- Only the Centauri Carbon publishes a flow rate (32 mm³/s, roughly 400 mm/s of line speed), so the other's speed claim cannot be checked.
