Bambu Lab nylon settings: temperatures, plate and drying

In Bambu Studio, pick the system preset named after your spool and keep its values. Bambu PA6-CF prints at 275 °C, PA6-GF at 265 °C, and PAHT-CF and PPA-CF at 290 °C, all on a 100 °C plate coated with glue stick. For another brand’s nylon, start from Generic PA (260 °C) or Generic PA-CF (290 °C).

Values below come from Bambu Studio’s system presets, Bambu Lab’s filament data sheets and its filament guide, as published on October 24, 2026.

What settings does nylon need on a Bambu Lab printer?

On a Bambu Lab printer, nylon needs a 260 to 290 °C nozzle and a 100 °C bed on a glue-coated PEI or Engineering plate. Shut the door and lid, and dry the spool at 80 °C for 8 to 12 hours. Carbon- and glass-filled grades need a hardened steel nozzle and flow capped at 8 to 10.5 mm³/s.

Bambu Studio names nylon by its chemical name, PA (polyamide). PPA is polyphthalamide, and CF and GF mark carbon- and glass-fiber filled grades.

In both tables, the first figure is what the preset sets. The range in parentheses comes from the data sheet for Bambu filaments and from the preset itself for the two Generic ones. Bambu Lab’s filament guide puts a tolerance of ±10 °C on its nozzle ranges.

Temperatures, plate and chamber

Bambu Lab’s filament guide gives a 100 to 120 °C bed for every nylon on these three plates, so the presets’ 100 °C agrees with both the guide and the data sheets. It marks the Cool Plate “Not recommended” and liquid glue “Not Recommended” for nylon, and the store pages list the Cool Plate SuperTack as not compatible.

PPA-CF’s range runs to 310 °C, above the 300 °C nozzle limit of the P1S and X1 Carbon. Bambu’s preset for both prints it at 290 °C.

The chamber targets are from the data sheets. Bambu Lab’s filament guide answers “NO” to removing the glass lid for any nylon, so keep the front door shut and the lid in place.

Cooling, speed, drying and AMS

All six presets keep the part cooling fan off for the first three layers and leave the auxiliary fan off. The volumetric limits are for the standard hotend. Bambu’s data sheets add:

• Print speed under 100 mm/s (under 130 mm/s for PA6-GF).
• Retraction of 0.8 to 1.4 mm at 20 to 40 mm/s.
• Bambu Support for PA/PET as the support material.

Bambu PA-CF, discontinued and replaced by PAHT-CF, keeps a preset at 290 °C and 8 mm³/s.

The AMS 2 Pro (Bambu Lab’s Automatic Material System feeder) dries at up to 65 °C, and the filament guide marks it “Not recommended” for drying nylon. Methods and times for each dryer are in drying filament for Bambu Lab printers.

Which nylon profile should you choose in Bambu Studio?

Choose the system preset named after your filament: Bambu PAHT-CF, Bambu PA6-CF, Bambu PA6-GF or Bambu PPA-CF. PAHT-CF and PA6-GF loaded through an AMS select their own preset, because Bambu Lab stores every printing parameter in the spool’s RFID tag. PA6-CF and PPA-CF cannot go through any AMS, so you choose their preset by hand.

For another maker’s nylon, use the preset that maker publishes, or start from Generic PA (unfilled) or Generic PA-CF (filled) and enter the maker’s values. Brands can be far apart. The Polymaker Fiberon PA6-CF preset that ships with Bambu Studio sets 300 °C, a 40 °C bed and 14 mm³/s; Bambu PA6-CF’s sets 275 °C, 100 °C and 8 mm³/s.

To keep edited values, create a custom filament. Click the Settings icon in the filament list and choose Custom Filaments, then Create New. Pick Generic PA or Generic PA-CF as the base. Bambu Lab’s wiki says only filaments made this way sync to the printer and can be assigned to an AMS slot.

Generic PA is the only preset here that does not demand a hardened nozzle. It asks for a nozzle hardness of 3 on the Rockwell C scale (HRC), and the filled presets ask for 40. Bambu Studio rates stainless steel at 20 HRC and hardened steel at 55.

Are the Bambu X1C nylon settings different?

Not in the slicer. Bambu Studio loads the same preset files for the X1 Carbon and the P1S: “Bambu PAHT-CF @BBL X1C”, for example, lists both printers’ nozzles. Nozzle temperature, bed, fan and flow are identical, and the P2S and H2D presets use the same nozzle temperatures and flow limits. The differences are in the hardware:

• Nozzle. The Bambu Lab X1 Carbon ships with a hardened steel nozzle and extruder gears, so it prints filled nylon as delivered. The P1S needs a hardened steel hotend first.
• Bed. The X1 Carbon’s bed reaches 110 °C on 220 V and 120 °C on 110 V. So it can print nylon above 100 °C and dry PPA-CF on the bed at 110 °C. The P1S stops at 100 °C.
• Rating. Bambu Lab’s spec sheets call PA “Ideal” on the X1 Carbon and “Capable” on the P1S, and carbon- or glass-fiber filament “Ideal” on the X1 Carbon and “Not Recommended” on the stock P1S.

Neither printer heats its chamber. The 60 °C chamber value some of these presets carry takes effect only on printers that do, such as the Bambu Lab X1E.

How do you print nylon on a Bambu Lab P1S?

To print nylon on a Bambu Lab P1S, fit a hardened steel nozzle for any carbon- or glass-filled grade and select it on the printer’s screen. Dry the spool, choose Bambu’s preset or Generic PA, and print on the glue-coated Textured PEI plate at 100 °C with the front door and glass lid closed.

Unfilled nylon needs no hardware change: Bambu Lab’s P1S upgrade guide lists PA among the filaments the stock stainless steel hotend suits. Which Bambu Lab models can print nylon at all is covered in Bambu Lab printers for nylon.

How to print nylon on a Bambu Lab P1S, step by step

1. Fit a hardened steel nozzle. PA6-CF, PA6-GF, PAHT-CF, PPA-CF and other filled nylons need one; unfilled PA does not. Bambu Lab’s first choice of size is 0.6 mm, and a 0.2 mm nozzle is not compatible. It also recommends hardened extruder gears on the P1S. Fitting a hardened steel nozzle walks through the swap.
2. Set the nozzle type. On the P1S screen, go to Settings > Accessories and select hardened steel and the diameter. In Bambu Studio, pick the matching printer preset, such as “Bambu Lab P1S 0.6 nozzle”.
3. Dry the spool. Use a forced-air oven at 80 °C for 8 to 12 hours, or the P1S bed. For bed drying, unload the filament, home the printer, lower the bed to the bottom and cover the spool with its box. Set the bed to 90 to 100 °C, time the 12 hours yourself and flip the spool halfway. PPA-CF needs an oven at 100 to 140 °C.
4. Load the filament. PAHT-CF and PA6-GF can go in an AMS. Put PA6-CF and PPA-CF on the external spool holder with no sharp bends in the feed path. Load them from Controls > Feeding on the screen and choose the preset in Bambu Studio. While it prints, keep the spool sealed with desiccant below 20% relative humidity.
5. Prepare the plate. Wash the Textured PEI plate the P1S ships with in dish soap and hot water, then coat it with Bambu Lab glue stick. Leave the bed at the preset’s 100 °C, which is the P1S maximum. The plates are compared in which build plate to use for nylon.
6. Close up and preheat. Shut the front door and keep the glass lid on. In a cold room, Bambu Lab suggests heating the bed to its maximum for 15 minutes before you start the print. Bambu Lab’s safety notes ask for a well-ventilated room or an air filtration or exhaust system.
7. Slice within Bambu’s limits. Keep the preset’s volumetric limit and a print speed under 100 mm/s (130 mm/s for PA6-GF). To reduce warping, Bambu Lab suggests infill of 50% or less, six walls at most, and a brim on large parts.
8. Watch the first layers. Lifting corners call for more glue, a brim or a longer preheat. Bubbles, stringing or a rough surface mean the filament is still wet. If extrusion thins or stops on a carbon-fiber grade, fiber may be building up in the nozzle. See fixing PA-CF clogs.
9. Remove the print. Let the plate cool before you flex the part off. Pull supports within 2 hours, before they absorb moisture and stick.
