Manufacturer-cited drying reference
Filament drying temperature chart: PLA to PPA-CF
Compare official product examples from 55°C PLA and PLA-CF through a 100–140°C PPA-CF cycle. Every row keeps the product, time, and drying method attached to the temperature so the chart can screen equipment without turning one maker's setting into a universal preset.
The cited examples span 55°C for PLA-CF to 140°C for one PPA-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.

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.
