Tips for printing PC on the Elegoo Neptune 3 Pro
- Dry your filament immediately before printing — PC is extremely hygroscopic. Even 2–3 hours of moisture exposure degrades print quality.
- This is an open-frame printer — build or buy an enclosure to prevent warping and layer delamination.
- Use a hardened steel nozzle for filled variants (glass-fiber, carbon-fiber) — standard brass wears quickly.
- PC is one of the most warp-prone materials. A brim of at least 5mm and an enclosure chamber above 45°C are strongly recommended.
