There are three main methods used for product development, that is, creating a design from an idea to a physical, three-dimensional prototype of a product.
Manufacturing in general can be a product development process that continuously cuts away material from a solid block, such as metal. This can be done manually or using Computerized machinery.
Injection molding has been around for years and is a manufacturing process used for producing products in large volumes. As the name suggests, parts are produced by injecting heated material into a mold.
So, what is 3D printing? Additive manufacturing is the process of producing three-dimensional objects from a computer file, and the part is built by adding material layer-by-layer.
These days, more companies in many different industries are harnessing the 3D printing process. The reason being it presents many significant advantages over the more traditional manufacturing methods of injection molding.
