If you think 3D printing is just a fantasy, think again. Learn how 3D printing works; making modern printers able to print 3D models using additive techniques.
3D printing is commonly defined as the means of creating three dimensional solid objects from a digital model. 3D printing applies additive manufacturing techniques. Quite unlike the conventional machining process where material is removed through cutting or carving, the additive manufacturing used in 3D printing sets layers upon layers to create a three dimensional image.
