describe the 3d printing process
user
3d printing is a process in which a three-dimensional object is built layer by layer using a computer-aided design (cad) program, instead of using traditional techniques to make the object. in 3d printing, a 3d model is designed, either in stl file format or another 3d program. the file is then loaded into a 3d printer, where it is printed layer by layer with special material. the material is heated and applied in thin layers over the course of the printing process. the result is a 3d object that can be used for a variety of applications.
