What is the primary role of slicing software in FDM?

The primary role of slicing software in Fused Deposition Modelling (FDM) is to convert 3D models into G-code, which is the programming language that 3D printers understand to execute printing tasks. During the slicing process, the software analyzes the 3D model and generates a series of layered instructions, detailing how the printer should move along the X, Y, and Z axes. This G-code contains commands for extruding filament, adjusting temperature, and even controlling the speed of the print head.

While slicing software does not create 3D models itself, it works with existing models created in CAD software or similar applications. It also does not manipulate filament types; instead, it focuses on the parameters needed to print a model based on the specified filament and printer characteristics. Additionally, while maintenance management can be important for 3D printers, such tasks are typically handled through separate software or manual procedures rather than through the slicing software itself. Thus, the conversion of 3D models to G-code is indeed the central function of slicing software in the FDM process.
