What is a 3D Printer Slicer?
What the slicer does
The slicer takes your 3D model, divides it into horizontal layers (slices), and generates G-code instructions for the printer: which paths to follow, at what speed, at what temperature, with how much extrusion. The G-code goes to the printer via SD card, USB or network.
