Printing tips

Drying recommendations:

Drying temperature:
In a drying oven: 100 °C to 140 °C for 8 to 12 hours.

On the heated bed of the X1 printer: 110 °C to 120 °C for 10 to 12 hours (less effective than a drying oven).

Important note: Higher temperatures within the drying range provide better results, but do not exceed 160 °C to avoid damaging the spool.

Storage tips:
Storage conditions: To prevent the filament from absorbing moisture, use an airtight storage container with desiccant during printing.
