3D Printing Technology

3d printing or additive manufacturing is a process of making three dimensional solid objects from a digital file. Working of 3d printing it all starts with making a virtual design of the object you want to create. This virtual design is made in a cad (computer aided design) file using a 3d modeling program (for the creation of a totally new object) or with the use of a 3d scanner (to copy an existing object). A 3d scanner makes a 3d digital copy of an object. 3d scanners use different technologies to generate a 3d model such as time-of-flight, structured / modulated light, volumetric scanning and many more. Processes and technologies not all 3d printers use the same technology.
