🔍 What Is a 3D Printing Slicer?
A slicer is the software that prepares your 3D model for printing. It takes your STL or 3MF file and slices it into layers, generating G-code instructions that your printer can understand. Slicers also let you tweak key print settings like layer height, infill, support structures, temperature, and speed—making them essential tools for achieving reliable, high-quality prints.
