3D Printing Tips and Tricks
- Before ordering the TPU filament check if your printer can print TPU as it is, if you have to do some modifications to it or if doesn’t allow you to print TPU;
- If your filament starts to get blocked around the wheels that push the filament into the hot end try to loosen a bit the screw that defines the pressure between the two wheels;
- If you get a lot of filament strings inside the mask reduce the speed to 65-70% directly in the printer;
