Despite the fact that 3D printing has been around for a long time, it remains a mystery to many people. The procedure begins with the creation of a 3D digital model of the item to be made. The data is then interpreted by the 3D printer, which layers the material until the object is complete. It’s the polar opposite of carving a sculpture or instrument out of wood. You’re layering the material to build something new, rather than carving out the extra material bit by bit to shape an object.
