Best Filament for Prusa Core One
About the Core One
Prusa Research's CoreXY single-toolhead printer. Enclosed design, heated chamber capability and input shaping pushing print speeds higher than the bedslinger MK4 family. Targets serious hobbyists and small production users who want one machine for both PLA showcase prints and PC engineering parts.
Top filament picks for the Core One
- High-speed PLA: takes full advantage of the Core One's speed envelope
- Prusament PLA: tight tolerance for clean prints at any speed
- Prusament PETG: functional, consistent, easy
- ASA: outdoor and heat-resistant parts; the enclosure helps with warping
- ABS: vapour-smoothable parts with the enclosure
- PC: high-temp engineering parts; the heated chamber is what makes PC practical
- PA-CF: stiffness and dimensional stability for engineering parts
- PETG-CF: lighter alternative to PA-CF
Why the enclosure changes things
Standard bedslinger printers struggle with ABS, ASA and PC because the print cools unevenly in open air. The Core One's enclosed CoreXY design maintains chamber temperature, which keeps these materials printing reliably at full size. Engineering materials that were previously aspirational on a Prusa become practical.
Speed considerations
- Use high-speed or high-flow PLA blends to take advantage of the speed
- Layer fan upgrades may help (depending on Core One firmware version)
- Hardened nozzle for matte or composite at higher speeds (more nozzle contact time)
- Dry your filament before high-speed prints (moisture failures are louder at speed)
Core One spares to keep
- Nextruder nozzles (Core One uses the same Nextruder family)
- Chamber temperature sensor (if applicable)
- PEI sheet for the Core One build plate size
- Heater cartridge and thermistor spares
- Filament sensor microswitch
