Materials for 3D Printing WHAT IS 3D Printing? The basic definition of 3D Printing is the action or process of making a physical object from a three-dimensional digital model, typically by laying down many thin layers of a material in succession. 3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file. The creation of a 3D printed object is achieved using additive processes. In an additive process an object is created by laying down successive layers of material until the object is created. Each of these layers can be seen as a thinly sliced cross-section of the object. 3D printing enables you to produce complex shapes using less material than traditional manufacturing methods. Adoption of 3D printing has reached critical mass as those who have yet to integrate additive manufacturing somewhere in their supply chain are now part of an ever-shrinking minority. Where 3D printing was only suitable for proto...
