Drying nylon and carbon-fibre nylon

PA11, PA6 and filled nylon are separate products. Their drying instructions should stay separate too.

Use the exact nylon grade's technical sheet. PA11, PA6 and a carbon-filled nylon are not interchangeable entries in a drying chart.

A named nylon example

Prusa specifies 90 °C for 6 hours for Prusament PA11 Carbon Fiber. This is not a setting for every PA6, PA12 or unfilled nylon spool. Source: Prusa, checked 25 October 2026.

Check the dryer before buying

Find the specified cycle first, then compare it with the equipment's operating range. Don't assume a dryer advertised for nylon can meet every nylon manufacturer's recommendation. Spool heat resistance is another separate check.

The drying table shows product names beside each source. If the row doesn't match your grade, follow the original data sheet instead.

Think through the full print

Drying immediately before a job is only part of the workflow. Decide how the spool will be protected while it feeds and where it will go afterwards. Check the printer and dry-box manuals for a supported feed route.

For a new arrangement, run a short job first and watch the spool turn. A good seal is no help if the reel binds or the filament catches at an outlet.

Avoid a false guarantee

There is no universal timer that proves all nylon is dry. A chamber hygrometer describes air around the spool; it doesn't directly measure moisture within the polymer. Follow the maker's cycle and evaluate the print result rather than using the display alone as a pass mark.
