3D printing, also known as additive manufacturing is a process of making three dimensional solid objects from a digital file. It turns digital 3D models into solid objects by building them up in layers. The technology was first invented in the 1980s, and since that time it has been used for rapid prototyping (RP). However, in the last few years, 3D printing has additionally started to evolve into a next-generation manufacturing technology that has the potential to allow the local, on-demand production of final products or parts thereof. It is possibilities to 3D print in a wide range of materials that include pure metals, metal alloys, ceramic, thermoplastic and various forms of food. Some of 3D printed metal, human organs are already being fitted into products that range from jet engines to human body. It continues to advance, and will provide low run, customized, and material efficient manufacturing. This webpage will provide an overview of 3D printing, as well as their past, present, and likely future application with video.
