The term slicer is used, among other things, in 3D printing technology and refers to the splitting of a 3D printed object into the individual layers that make up a 3D printed object.
A slicer handles the software division of a 3D printed model into a number of thin layers. It adds machine-readable control instructions to the printing process, from which the 3D printer derives its printing process. The code used for this is the G-code. The software-based slicing breaks the 3D printed object into flat layers, the creation of which is ensured by the movements of the extruder, the laser, the print bed or other components of the 3D printer.
