Question about Filapen 3D pen with 10 filaments

No, you cannot use any 1.75 mm thick filament for the Filapen Premium 3D pen. The pen only works with PCL (polycaprolactone) filaments. The use of PLA (polylactide) or other filament types can damage the pen and render it unusable. It is therefore important to use only original Filapen PCL filaments.
