Most 3D printers come with preset functions for loading and unloading filaments. The nozzle needs to be heated ... uncoil from the spool, as it can create a knot that would cause it to get stuck ...

The goal is to make 3D printing more sustainable," says senior ... molten polymers are extruded through a heated nozzle layer-by-layer to build a part. Software, called a slicer, provides ...

engineers usually set the 3D printer to around 200 Celsius (390 Fahrenheit) to make sure the material is going to be melted as it’s extruded from a little nozzle, but can then harden back into form.

It creates small layers that bond together to ultimately create an object ... Following the 3D file, the printer now heats the materials and extrudes through the nozzle as it moves, one layer ...

One could use speed-modulated ironing to create artistic effects by ... In speed-modulated ironing, the first nozzle of a dual-nozzle 3D printer deposits a heat-responsive filament and then ...
