How to use this number
- The first sentence is the span and the median of the official tables it names. It is not a new setpoint.
- Stay inside that published temperature span and that published time span. The median is the middle of those tables.
- Use the product row in the table before you start. One brand can sit at either end of the range.
| Material | Tables | Median | Range |
|---|---|---|---|
| TPU | 19 | 70 °C (158 °F) | 50–80 °C (122–176 °F) |
| PA/nylon | 33 | 90 °C (194 °F) | 70–140 °C (158–284 °F) |
Range Fahrenheit is the value the maker published. Median Fahrenheit is the conversion of the median Celsius. This is not a recommendation.

| 1 | SUNLU · TPU95A | TPU | — | |
Product-page nozzle is 190–210 °C (374–410 °F) and the bed is 50–60 °C (122–140 °F). The drying dataset lists 50–60 °C (122–140 °F) for 6–8 h from the SUNLU wiki, checked 18 October 2026. The product row stores 50–60 °C (122–140 °F) and 8 h from that same wiki. | ||||
| 2 | Prusament · TPU 95A | TPU | — | |
Open Filament Database, dataset imported 13 October 2026, lists a nozzle of 220–240 °C (428–464 °F) and a bed of 55–75 °C (131–167 °F). The drying dataset lists 60 °C (140 °F) for 4–6 h from Prusa's drying article, checked 18 October 2026. The product row stores 60 °C (140 °F) for 6 h as that article's material default. | ||||
| 3 | Bambu Lab · TPU 95A HF | TPU | Datasheet | |
Technical data sheet and the drying dataset both list 70 °C (158 °F) for 8 h, checked 18 October 2026. Nozzle 220–240 °C (428–464 °F), bed 30–35 °C (86–95 °F), print speed up to 200 mm/s. | ||||

Open Filament Database nozzle 245–260 °C (473–500 °F) and a bed of 50 °C (122 °F), print speed up to 70 mm/s. The drying dataset lists 95 °C (203 °F) for 7 h from Overture's drying guide, checked 18 October 2026. The product row stores the same 95 °C (203 °F) for 7 h. | ||||
| 5 | Polymaker · Polymide Copa PA6 | PA6 | Datasheet | |
PolyMide CoPA TDS and the drying dataset both list 100 °C (212 °F) for 8 h, checked 18 October 2026. Nozzle on the Open Filament Database record is 250–290 °C (482–554 °F) and the bed is 80–100 °C (176–212 °F). | ||||

Copy the cycle that belongs to the spool. How drying works, PETG's cycles, nylon as a print material, and why an oven is a separate question are the overlaps. The TPU rows live on TPU drying temperature and time. The nylon rows live on PA drying temperature and time.
TPU is not one number
SUNLU TPU 95A lists a nozzle of 190–210 °C (374–410 °F) and a bed of 50–60 °C (122–140 °F). The drying dataset lists 50–60 °C (122–140 °F) for 6–8 h, SUNLU wiki checked 18 October 2026. The product row stores 8 h rather than the 6–8 h span. Prusament TPU 95A lists 220–240 °C (428–464 °F) and a bed of 55–75 °C (131–167 °F). The dataset lists 60 °C (140 °F) for 4–6 h from Prusa's drying article, checked the same day. The product row stores 6 h. Bambu TPU 95A HF lists 220–240 °C (428–464 °F), a bed of 30–35 °C (86–95 °F), speed up to 200 mm/s, and 70 °C (158 °F) for 8 h on both the sheet and the dataset.
The same table, same check date unless noted, also has Flashforge TPU at 50 °C (122 °F) for 6 h, checked 24 October 2026, and Anycubic TPU at 70–80 °C (158–176 °F) for 8–12 h. Bambu's other TPU sheets on that table, 85A, 90A, and TPU for AMS, are 70 °C (158 °F) for 8 h. A 50 °C (122 °F) cycle and an 80 °C (176 °F) cycle are both published. They are not interchangeable.
Nylon is wider still
Overture Easy Nylon lists 245–260 °C (473–500 °F), a 50 °C (122 °F) bed, speed up to 70 mm/s, and 95 °C (203 °F) for 7 h. PolyMide CoPA lists 250–290 °C (482–554 °F), a bed of 80–100 °C (176–212 °F), and 100 °C (212 °F) for 8 h. eSUN's ePA page, in the dataset, is 70 °C (158 °F) for more than 12 h. Prusament PA11 on that table is 90 °C (194 °F) for 6–8 h. Creality's general PA guidance is 80–90 °C (176–194 °F) for 8–12 h. Those are the published rows. The editorial 70–80 °C (158–176 °F) band does not cover CoPA or Overture.
Pros and cons
Pros
- Every cycle on this page is a drying-dataset row with a manufacturer URL. The editorial 50–55 °C (122–131 °F) and 70–80 °C (158–176 °F) bands are not used as the answer.
- Where the product row stores only the top of a time range, the dataset's 4–6 h or 6–8 h is kept as well.
Cons
- The supplied comments talk about room humidity and about buying a dryer. They do not state a TPU or nylon setpoint.
Printer considerations
- Do not put SUNLU's 50–60 °C (122–140 °F) TPU cycle on PolyMide CoPA, and do not put CoPA's 100 °C (212 °F) cycle on TPU. The brands already disagree inside TPU.
- eSUN ePA in the drying dataset is 70 °C (158 °F) for more than 12 h, product page checked 18 October 2026. Prusament PA11 on the same table is 90 °C (194 °F) for 6–8 h. More than 12 h is the published qualifier. It is not a license to keep going until the spool looks dry.
- A score-8 comment says a dried TPU roll went bad again in 2–3 hours at about 65 percent room humidity. That duration is the comment. No sheet here states it.

Questions
Which TPU number should I copy?
The one on that spool's row. SUNLU TPU 95A is 50–60 °C (122–140 °F) for 6–8 h. Prusament TPU is 60 °C (140 °F) for 4–6 h. Bambu TPU 95A HF is 70 °C (158 °F) for 8 h. Flashforge TPU in the same dataset is 50 °C (122 °F) for 6 h, checked 24 October 2026. Anycubic TPU is 70–80 °C (158–176 °F) for 8–12 h, TDS checked 18 October 2026. The full TPU table is TPU drying. Drying in general and PETG drying are the other cycles.
Is nylon always hotter than TPU?
Not as a rule you can apply blindly. eSUN ePA is 70 °C (158 °F) for more than 12 h, which overlaps the hotter TPU rows. PolyMide CoPA is 100 °C (212 °F) for 8 h, and Overture Easy Nylon is 95 °C (203 °F) for 7 h. Nylon printing is the print page. Oven drying is the appliance warning. The nylon rows are on PA drying.
