Most people use stereolithography or fused filament fabrication, which involves layering of heated plastic filament. Software may be slightly different depending on your 3D printer’s method.
You might need to look elsewhere for more advanced tasks surrounding the 3D modeling itself. Many models come with a 3D printer program that does the basics like slicing your 3D models into instructions called G-Code for the printer to know what to print. It also involves 3D scanning of simple objects you’d like to replicate, aspects of CAD design and associated tools like slicing, in order to make your model printer-ready, and save it as an appropriate file, i.e. It allows you to import existing three-dimensional models you’ve found on the net and manipulate them. 3D printing software can be a combination of software types and tools.
