Module 1: Additive Manufacturing Introduction and CAD-CAM for 3D Printing

2025?m

In the context of FDM 3D printing software, what is the primary function of a slicer program?

(i) To create the initial 3D part geometry (CAD)
(ii) To convert a 3D model (e.g., STL file) into instructions (G-code)
(iii) To repair mesh errors in the 3D model
(iv) To monitor and remotely control the 3D printer hardware

Answer: (ii) To convert a 3D model (e.g., STL file) into instructions (G-code)

A slicer divides the 3D model into thin layers and generates the toolpaths needed to manufacture each layer. It then converts those toolpaths into printer instructions, commonly G-code, specifying movements, speeds, temperatures, extrusion, and other machine parameters.
