In recent years, 3D printing has developed significantly and can now perform crucial roles in many applications, with the most important being manufacturing, medicine, architecture, custom art and design

  3D printers thus use additive manufacturing or direct digital manufacturing technology to produce proto type of a product.

  3D printers use Computer Aided Designing (CAD) software like Siemens NX to create a digital blue print first. The object is then built layer by layer.
