3D printing is a well-established industrial technology for prototyping and manufacturing, particularly popular with the aerospace and defence sectors. Also known as additive manufacturing (AM), 3D printing is the process of making a solid 3D object from a digital computer aided design (CAD) file. The printer adds successive layers of material together until the final object has been created. This is different from traditional manufacturing methods like CNC machining, which removes material from a solid block using rotating tools or cutters.
3D printing is a rapid production method with minimal waste material. Its design flexibility means users can manufacture bespoke objects for a low cost. These advantages have made it increasingly popular as a production method in the manufacturing industry.
