WARNING: When melted, XSTRAND® filament can be abrasive due to its glass reinforcement. Printing with XSTRAND® may reduce lifespan of brass nozzles and extruder driving wheels. It is advised to use hardened steel nozzles and extruder driving wheels.

IMPORTANT NOTICE: We recommend the use local exhaust ventilation equipped with HEPA filters to remove ultra-fine particles and/or carbon filters to remove VOCs on all 3D printers.

Nozzle Settings

Hardened steel nozzle is highly recommended to print XSTRAND® filaments. When melted, XSTRAND® filament can be abrasive due to its glass reinforcement. Using hardened steel nozzles and extruder driving wheels is advised.

Storage and Drying

XSTRAND® filaments must be stored in a dark and temperate location. It is recommended that the product remain closed in its original packaging until use.
