What temperature should I print Nylon (PA) on the Prusa MK3S+?

Start at 260°C for the hotend and 90°C for the bed, then run a temperature tower across 250–275°C to dial in your exact filament brand.

What print speed works for Nylon (PA) on this printer?

Around 65 mm/s is a safe starting point on the Prusa MK3S+. It can go faster once the profile is tuned, but start conservative for clean walls.

What retraction should I use?

Use about 1 mm of retraction (direct drive needs very little). If you see stringing, raise retraction speed before distance and dry the filament.

Do I need an enclosure for Nylon (PA) on the Prusa MK3S+?

Yes — Nylon (PA) needs an enclosure to avoid warping, and the Prusa MK3S+ is open, so add one or expect warping and cracking on larger parts.

Nylon (PA) settings for the Prusa MK3S+

Workable with mods

⚡ Quick answer: Print Nylon (PA) on the Prusa MK3S+ at 260°C hotend, 90°C bed, 65 mm/s, 0% part-cooling fan and 1 mm retraction. Run a temperature tower to fine-tune your exact spool.

These are tuned starting settings for printing Nylon (PA) on the Prusa MK3S+. The Prusa MK3S+ has a direct-drive extruder with an all-metal hotend, so we set the hotend to 260°C and the bed to 90°C. Nylon (PA) is a tough, wear-resistant engineering material that demands drying and high heat.

⚠️ Nylon is extremely hygroscopic and needs an all-metal hotend — dry it before every print. The open Prusa MK3S+ works for small parts, but expect warping on anything large.

Recommended Nylon (PA) profile

Hotend temperature	260°C (tower 250–275°C)
Bed temperature	90°C
Print speed	65 mm/s
Retraction	1 mm (direct drive)
Part cooling fan	0%
Bed adhesion	Glue stick or PA-specific sheet; use a brim.
Nozzle	Hardened recommended
Difficulty	Advanced

💡 Best uses for Nylon (PA): gears, living hinges and tough functional parts.

Troubleshooting Nylon (PA) on the Prusa MK3S+

Problem	Fix
Stringing or fine hairs	Dry Nylon (PA) before printing, drop the hotend a few degrees below 260°C, and raise retraction toward 1.4 mm. Damp filament is the No. 1 cause of stringing.
Poor first-layer adhesion	Glue stick or PA-specific sheet; use a brim. Re-level the bed, set a slightly squished first layer, and wipe the sheet with IPA so it is grease-free.
Blobs, zits or rough walls	Slow the outer wall, enable coasting/wipe, and keep retraction near 1 mm. Keep the part-cooling fan low so layers bond and warping stays down.
