What is the main purpose of slicing software in 3D printing?

The main purpose of slicing software in 3D printing is to prepare the CAD model for printing. Slicing software takes a three-dimensional model created in CAD and converts it into a format that the 3D printer can understand, typically generating a G-code file. This process involves breaking down the model into horizontal layers (slices) that the printer will follow layer by layer to build the object.

In addition to slicing the model, the software also allows users to set various print parameters, such as layer height, print speed, and support structures, which are crucial for achieving the intended design and mechanical properties of the printed part. Ultimately, the slicing software plays a pivotal role in ensuring that the 3D printer can accurately reproduce the desired object based on the original CAD file.
