ABSTRACT
In this chapter we discuss how a 3D model is printed from a digital design in 3D printing, sometimes referred to as additive manufacturing. 3D printing is an additive technique, as opposed to conventional subtractive procedures. It starts with a solid item and reduces or carves it until it has the desired shape. In essence, a real product is moulded by a 3D printer using a digital plan. For instance, some 3D printers build an object layer by layer using heated materials like plastic. Eventually, the layers stack up in three dimensions to form the final thing.
Despite being developed in the late 1980s, 3D printing didn’t receive much attention until the 1990s. Like any new technology, 3D printing was initially viewed by many as something that could only be imagined.
