3D printing, also known as additive manufacturing, is a process in which an object is built up layer by layer like a cake. First we take the 3D model of the object we want to print and slice it into multiple layers, each layer being thinner than a sheet of paper.
Our 3D printers then take all this layer data and build up the object one layer at a time. The materials and exact process varies depending on the type of 3D printer. The full color 3D printers we use work by putting down an extremely thin layer of powder and gluing the layer together with colored adhesive, moving the object down slightly and putting down a new layer of material. This process is repeated for each layer of the object.
