Manufacturer-cited drying reference
Filament drying temperature chart: settings by exact product
A useful chart must preserve which company, product, and drying method produced each number. These entries are official examples for capability screening—not universal presets for every spool that shares the same material label.
The cited examples span 55°C for PLA-CF to 100°C for one PA6-CF. Even two products both called PA6-CF differ by 20°C. Check the current data sheet, drying method, spool heat rating, time, and in-use humidity requirement before starting a cycle.
Direct answers
What a drying chart can safely tell you
What temperature should filament be dried at?
Use the exact filament maker's current setting. Material-family charts are only a starting index because formulations and drying methods differ.
Can lower heat be replaced with more time?
Do not assume so. A longer low-temperature cycle is equivalent only when the filament manufacturer explicitly provides that alternative.
What if the dryer exactly matches the target?
Treat that as a narrow paper match. A stated maximum does not prove every point in a loaded chamber reaches and holds that temperature.

Official examples, kept separate
| Material | Official product or family | Temperature | Time | Method / context |
|---|---|---|---|---|
| PLA / PLA-CF | Creality material-family guidance | 55°C | 8–12 h | Creality filament dryer |
| PLA-CF | Polymaker PolyLite PLA-CF | 55°C | 6 h | Product drying setting |
| PETG | Polymaker PETG | 60°C | 6 h | Product drying setting |
| ABS | Polymaker PolyLite ABS | 70°C | 6 h | Product drying setting |
| ASA | Polymaker ASA | 70°C | 7 h | Product drying setting |
| TPU 95A | Polymaker PolyFlex TPU95 | 70°C | 8 h | Product drying setting |
| PC | Polymaker PolyLite PC | 75°C | 6 h | Product drying setting |
| PA6-CF | Bambu Lab PA6-CF | 80°C | 8–12 h | Blast drying oven |
| PA6-CF | Polymaker PolyMide PA6-CF | 100°C | 8 h | Technical data sheet cycle |
Read this literally: the table says what each cited source says. It does not average conflicting values, create a family-wide “safe maximum,” or claim that a dryer's display equals the temperature inside the spool.
Why the numbers diverge
Four variables a one-line chart usually hides
Additives change the material.
Base polymer, reinforcement, modifiers, pigments, and manufacturing choices can change moisture response and heat tolerance.
Airflow changes the process.
A blast oven, consumer filament dryer, heated chamber, and sealed dry box are not interchangeable descriptions.
The reel can fail first.
A polymer's drying temperature can exceed the supplied spool's heat tolerance. Follow respooling instructions when the maker provides them.
Drying may need to continue.
Highly moisture-sensitive filament can require low-humidity storage or heated feeding throughout the print, not just a pre-cycle.
Safe decision path
Resolve the setting in this order
- 01Identify the exact product.
Use the manufacturer's current page or data sheet, not a generic material name printed in a third-party chart.
- 02Record method, temperature, and time together.
Do not detach the temperature from the equipment type or extend time without an approved alternative cycle.
- 03Check the spool and equipment limits.
Reject a dryer below the requirement and confirm that the reel, chamber, timer, and ventilation are suitable.
- 04Plan storage and print-through handling.
Dry filament can reabsorb moisture. Follow any humidity target and feed-from-dryer instruction for the exact product.

Documents behind the chart
Use purpose-built, manufacturer-approved equipment, confirm ventilation and electrical safety, and never exceed the exact spool's heat rating.
