Overview:
Laminated Object Manufacturing (LOM) is developed by Helisys of Torrance, CA, In it, layers of adhesive-coated sheet material (like paper, plastic, or metal) are successively glued together and cut to shape with a knife or laser cutter, so as to form a prototype.
This technology has the following advantages:
Low cost due to readily available raw material
Paper models have wood like characteristics, and may be worked and finished accordingly Dimensional accuracy is slightly less than that of Stereolithography and Selective laser sintering but no milling step is necessary.
Relatively large parts may be made, because no chemical reaction is necessary
Material: 1) Colophony
2) China
3) Metal
