Frequently asked questions
What filament can I use with it?
Check the manual for the recommended filament diameter and material before loading. Using filament outside the recommended spec can cause jams or poor melting at the nozzle.
Is it safe to use indoors?
The nozzle gets hot and melting plastic releases fumes, so keep it away from children and pets, use it in a ventilated room and avoid touching the tip while in use.
