3d printing wiki:
ensional printing (more commonly referred to the abbreviation 3DP) is a type of rapid prototyping system developed by MIT in the late 1980s.Using an adapted inkjet printing system, layers of a fine powder (either cornflour or plaster) are selectively bonded by "printing" a water-based adhesive from the inkjet printhead in the shape of each cross-section as determined by a CAD (computer aided design) file.Alternately, these machines feed liquids into individual jetting heads which squirt tiny droplets as they are scanned to form a layer of the model. The liquid hardens after being deposited. Once a single layer has been deposited, a milling head may be employed to ensure uniform thickness before the next layer is deposited. The technique is typically very slow, but can obtain high resolution, often comparable to a CNC milling machine. The materials employed result in fragile parts. Materials available for spraying include glue, wax, starch, and photopolymer. Photopolymer Phase machines employ an ultraviolet (UV) flood lamp mounted in the print head to cure each layer as it is deposited.
