http://www.printo3d.com/how.html said:With that there are many different types of 3D printing methods. Our company uses a printing technology called Fused Deposition Modeling (FDM). Imagine taking two cartridges of a material similar to weed whacker wire and feeding it separately into a melting pot. This ABS wire is .07" in diameter when comes out of the cartridges. Once melted in the print head, which contains two needle like nozzles the material is then able to be extruded precisely. These needle like nozzles produce .01" or .013" diameter extrusions. A model material is extruded from one of these nozzles and a second material called support material is extruded out the second nozzle. The model material is what a printed model is made out of, while the support material is used to support areas of a part while being built. Once a part is finished the support material is then broken away from the part and disposed. After the support material is broken away the model is then ready to be used. The model can also be go through several different post-processes including painting, patching, or even attaching two smaller models together to make one large model...
