In the 3D printing process, a physical object is produced from a 3D digital model. This generally occurs by the laying down of successive thin layers of material to bring the digital model to life.
The steps
involved in this process will vary depending on the type of printer and
the raw materials involved, but generally they are as follows:
1: A 3D model is created using a modelling package or 3D scanner, saved as a Computer Aided Design (CAD) file
2: The user slices the CAD file and uploads it to the printer
3: The printer reads and creates each 2D slice to form a 3D object
