3D Printing and the Additive Manufacturing Process

Additive manufacturing (AM) is a process where an object is created by adding layer-upon-layer of material. This basic process requires the use of a computer, CAD software, the material(s) and the appropriate machine to fabricate the end result. AM has been used in many applications. At first, it was used in Rapid Prototyping (RP). Today, AM is used to create end-products used in many different applications, from aerospace, automotive and even biomedical prosthetics. AM can create highly customizable products, and it’s this advantage that is being exploited in today’s world of manufacturing. 3D printing and AM are almost interchangeable. AM is the broader term, encompassing processes such as Rapid Prototyping (RP) which focused on creating preproduction visualization models, but the models weren’t actually used in the end product. Rapid Tooling (RT) the production of tooling to be used in another process like cores, patterns, or jigs. Direct Digital Manufacturing (DDM) the production of finished products directly from a computer file without the need of tooling. Layered Manufacturing (LM) are computer-aided manufacturing processes in which parts are made relatively quickly in sequential layers. 3D printing is a term that most people are familiar with. It’s a term that many envision will be used in our homes in the near future. So, what exactly is 3D printing then? 3D printing is actually a very broad term as…
