Filament
Can your AMS 2 Pro, dry box or kitchen oven dry nylon at 80 °C?
Set the drying temperature your spool's maker publishes against what each piece of equipment is rated to reach, and check whether that maker rules any of it out. Then you can tell whether what you own will do the job, or whether you need something that runs hotter.
The short answer
For nylon, the AMS 2 Pro will not get there, and neither will a sealed box of desiccant. A kitchen oven depends on who made the spool: Bambu's data sheets for its PA6-CF, PAHT-CF and PPA-CF rule one out. An enclosed Bambu printer has a published heated-bed method. The AMS HT is rated to 85 °C, which is Bambu's AMS HT setting for PA, PA6-CF/GF and PAHT-CF/GF, but Bambu marks its PPA-CF Not compatible with it. First, check the number for your own spool. Not every nylon is dried at 80 °C.
- AMS 2 Pro. Bambu rates it to 65 °C, reached only when the room is above 25 °C. Bambu's drying table marks every nylon row Not compatible for it. The AMS 2 Pro spec does list PA and PAHT-CF under drying, but with an asterisk: Bambu says those filaments need a higher drying temperature and the AMS 2 Pro cannot dry them completely.
- Sealed box with desiccant. It has no heat source, and every drying setting in Bambu's and Prusa's tables is 45 °C or higher. Its job is keeping a dried spool dry.
- Kitchen oven. It depends on who made the spool. Bambu's data sheets for its PA6-CF, PAHT-CF and PPA-CF say a kitchen or microwave oven is not compatible for drying them. They call for a large enough oven with even heat, such as a forced-air drying oven, with the spool kept away from the heater. Polymaker says a household convection oven can work at a low, stable temperature. Where the maker allows an oven, yours has to accept the setting and hold it. An 80 °C setting works out to 176 °F.
- Enclosed Bambu printer. For the H series, X series, X2D, P2S and P1S, Bambu's heated-bed method for PA6-CF/GF and PAHT-CF/GF is a bed setting of 90–100 °C for 12 hours, with the spool covered. Unload the filament from the toolhead and clear the bed first, as Bambu's steps say. Bambu says the open-frame P1P, A1, A1 mini and A2L cannot be used to dry filament on the heated bed.
- AMS HT. Bambu rates it to a maximum of 85 °C, and its AMS HT setting for PA, PA6-CF/GF and PAHT-CF/GF is 85 °C for 12 hours. Bambu's drying table marks PPA-CF, which Bambu's data sheet describes as a fiber-reinforced nylon, Not compatible with it. The AMS HT dries only with its own power cable plugged in, and some printers need extra parts to connect it.
First, find the number for your spool
If your 80 °C came from Bambu's filament guide, or from its PA6-CF or PAHT-CF data sheet, it is the setting for a forced-air oven, which Bambu also calls a blast drying oven. Bambu's data sheets give it under "Drying Settings before Printing", and the store page for each of these filaments links its data sheet under Download. Some other nylons carry higher numbers, and the last three rows below go above the AMS HT's maximum.
| Nylon | Published by | Drying setting | Against the AMS HT's 85 °C maximum |
|---|---|---|---|
| Bambu PA6-CF/GF, PAHT-CF/GF | Bambu drying guide, filament guide and data sheets | 85 °C, 12 h in the AMS HT; 75–85 °C, 8–12 h in a forced-air oven (80 °C, 8–12 h in the filament guide and data sheets) | Matches it |
| Bambu PPA-CF | Bambu drying guide and PPA-CF data sheet | 100–140 °C, 8–12 h in a forced-air oven; Not compatible with either AMS | 15–55 °C above it |
| Prusament PA11 Carbon Fiber | Prusa drying guide | 90 °C, 6 h | 5 °C above it |
| PolyMide CoPA | Polymaker technical data sheet | 100 °C, 8 h | 15 °C above it |
Prusa's advice when choosing a dryer applies to any brand: check that its specifications match your filament's drying temperature. The AMS HT's 85 °C maximum is below the last three settings, so it cannot run them as published.
Bambu's settings by material and equipment
Bambu's table has four columns, one per drying route, and some cells read Not compatible. The heated-bed figure is the bed setting, not the spool's temperature.
| Material | AMS 2 Pro | AMS HT | Forced-air oven | Heated bed |
|---|---|---|---|---|
| PLA Basic, PLA Matte | 45 °C, 12 h | 45 °C, 12 h | 50 °C, 8 h | 60–70 °C, 12 h |
| PETG, PETG-CF | 65 °C, 12 h | 65 °C, 12 h | 60–65 °C, 8 h | 75–85 °C, 12 h |
| TPU for AMS, TPU 95A HF | 65 °C, 12 h (may not fully dry TPU) | 75 °C, 18 h | 70 °C, 8 h | 80–90 °C, 12 h |
| ABS, ASA | Not compatible | 80 °C, 8 h | 75–85 °C, 8 h | 90–100 °C, 12 h |
| PC | Not compatible | 80 °C, 8 h | 75–85 °C, 8 h | 90–100 °C, 12 h |
| PET-CF | Not compatible | 80 °C, 12 h | 80 °C, 8–12 h | 90–100 °C, 12 h |
| PA6-CF/GF, PAHT-CF/GF | Not compatible | 85 °C, 12 h | 75–85 °C, 8–12 h | 90–100 °C, 12 h |
| PVA | Not compatible | 85 °C, 18 h | 75–85 °C, 8–12 h | 90–100 °C, 12 h |
| PPA-CF, PPS-CF | Not compatible | Not compatible | 100–140 °C, 8–12 h | 110–120 °C maximum, 10–12 h (less effective than a convection oven, Bambu says) |
Bambu marks drying before use as Required for TPU, PC, PET-CF, PVA, PPS-CF and the nylons, and Recommended for PLA Basic and Matte, PETG, ABS and ASA. Its separate filament guide lists some oven figures differently, such as PETG at 70 °C and PVA at 55 °C. For nylon, the guide's 80 °C for 8–12 hours sits inside the range above. Bambu's notes on the AMS HT name PVA, PPS-CF and PPA-CF as materials that may not dry fully in it, and the table goes further for the last two, marking them Not compatible.
Why nylon is the hard case
Nylon takes up water fast. In Prusa Polymers' own test at 24 °C and 22% humidity, Prusament PA11 Carbon Fiber absorbed 0.20% moisture in 24 hours and 0.50% in 7 days. Prusament PETG, tested the same way, absorbed 0.07% and 0.10%. That works out to five times as much for the nylon after a week. Prusa names polyamide among the highly hygroscopic materials that should be stored dry or dried before every print. Still choosing a material? See choosing filament by what the part has to survive.
Drying and keeping dry are different jobs
Bambu's table has two columns for this: drying before use, and desiccant protection during use. For nylon, both read Required. The first is a removal job, and it needs heat held for hours. The second is a prevention job, which is what a sealed box with desiccant does. Polymaker describes airtight desiccant containers as good for storage after drying and less effective for drying itself.
So a wet spool and only a dry box is a removal problem, and the box has no heat to solve it with. A dry spool is only a prevention problem, and the box handles it. The AMS 2 Pro can hold a dried spool of plain nylon too: its spec lists PA among the filaments it feeds, and it offers sealed storage and ships with desiccant. Filament with carbon or glass fiber is on its not-supported list, apart from Bambu's own PLA-CF, PAHT-CF and PETG-CF. See which filaments the AMS cannot feed.
Traps worth checking
- Room temperature. The AMS 2 Pro reaches 65 °C only when the room is above 25 °C, which works out to 77 °F. Both AMS units show real-time temperature on screen and in Bambu Studio and Bambu Handy.
- Printing while drying. Bambu lowers the drying temperature once a print starts, usually to below the filament's softening point.
- No standalone drying. Both AMS units dry only when connected to the printer by the 6-pin cable, with the printer on and set to drying mode. The AMS HT also has to be plugged in with its own included power cable; the printer cannot power its drying.
- Power for an AMS 2 Pro. On A1, A2L, P1 and X1 series printers, each AMS 2 Pro needs its own Switching Adapter to dry. H2 series, P2S and X2D printers can power one AMS 2 Pro for drying, and each additional unit needs its own adapter.
- The spool. Bambu warns that some third-party spools may not be heat-resistant enough and could deform during heated-bed drying. Bambu's PA6-CF and PAHT-CF data sheets rate their PC + ABS spools to 90 °C, under "Spool Material". Prusa says its older black spools can be heated safely to 45 °C; above that, add a screw with at least 65 mm of thread to hold the sides together. The glue in its older gray spools withstands up to 90 °C. Prusa says its spools made since October 2025 resist drying temperatures up to 90 °C (black, standard filaments) and 150 °C (gray, high-temperature filaments). Check yours before an 80 °C cycle.
- Kitchen ovens. Bambu's oven figures are for a forced-air oven, which its filament guide calls a blast drying oven. Polymaker notes that without good airflow, drying can take longer or need higher temperatures. Prusa warns that home ovens measure temperature imprecisely and that many cannot be set low enough, and advises an external thermometer.
What to check on your own equipment
- Your spool's drying temperature and time, from its maker's data sheet or drying guide.
- Your equipment's published maximum drying temperature, which must be at or above the spool's figure. Bambu calls it "Highest Temperature" on the AMS 2 Pro spec and "Maximum Temperature" on the AMS HT spec. Some makers publish a temperature range around the spool instead of one maximum. If a dryer does not publish a figure at or above your spool's drying temperature, ask its maker before relying on it for nylon.
- For an oven: first, whether your spool's maker allows a kitchen oven at all. Bambu's PA6-CF, PAHT-CF and PPA-CF data sheets do not. Then the lowest bake temperature in the owner's manual, whether it has a convection (fan) setting, and a thermometer reading taken next to the spool.
- For your printer: whether it is on Bambu's enclosed heated-bed list. The P1S has no built-in drying function, so you set the bed temperature and track the time by hand. Whether your printer can print nylon at all is covered in the five limits that decide whether your printer can run a filament.
- For an AMS: spool size. Both units list spools 50–68 mm wide and 197–202 mm across. See will this spool fit my AMS.
- For an AMS HT: the parts that connect it to your printer. X1 and P1 series printers need an additional buffer for one unit or an AMS Hub for several; a Combo, sold with an AMS, includes one buffer. A P2S bought without an AMS needs the P2S filament buffer. A1 series printers need the A1 Series AMS Hub, bought separately. H2 series and X2D printers come with a buffer, and the A2L takes one AMS with no extra parts. Bambu's connection guide lists the parts for every model.

What this page does not tell you
- Bambu's own documents do not agree on every figure. Its filament guide and drying guide list some oven settings differently, and its pages name different printers as needing an AMS 2 Pro power adapter; the adapter list on this page includes every printer any of them names. For PA6-CF and PAHT-CF, every Bambu oven figure falls between 75 °C and 85 °C.
- Heated-bed figures are bed settings. Bambu does not publish the temperature a spool reaches on the bed.
- Home ovens vary, and many measure temperature imprecisely or cannot be set low enough. Check yours with a thermometer next to the spool.
- Data sheets get revised. The Prusament sheets cited are dated 2022, the Polymaker sheet is version 5.4, Bambu's PA6-CF and PAHT-CF sheets are version 3.0, and its PPA-CF sheet is version 1.0. Check the version on the sheet for your spool.
- This page does not cover other makers' filament dryers. For one, compare its published maximum drying temperature with your spool's figure, and ask its maker before relying on it for nylon if it publishes no such figure.
