5 free 3D printer slicers to try

A 3D slicer is one of the essential tools that every 3D printing enthusiast needs in their arsenal. After designing your files in a 3D modeling program, you export them to the slicer, mostly in STL, OBJ, or 3MF format, which turns them into instructions that the 3D printer understands, called the G-code. The G-code contains commands like how the nozzle should move, speed settings, layer height, and temperature settings, together with other settings. Beyond slicing the file, a 3D slicer is also helpful for customizing the settings of your design to achieve the best results. Below are five popular free 3D slicers you can use in your next project.
