  • Do not over extrude filament when loading. As soon as the filament start protruding from the nozzle, stop. Loading any faster will cause the filament to get caught in extruder gear.

    Fast shipping and high quality product

    I recently ordered 2 rolls of TPU. I received them in 4 days from he time I ordered. The price was competitive. I ran the first print today and it was flawless. The translucent blue is beautiful!
