ABSTRACT
Laminated Object Manufacturing (LOM), is a rapid prototyping (RP) technique that produces three-dimensional models with paper, plastic, or composites. Helisys, Corp. in Torrance, CA developed LOM, led by Michael Feygin. LOM is actually more of a hybrid between subtractive and additive processes, in that the models are built up with layers of material, which are cut individually by a laser in the shape of the cross section of the part. Hence, as layers are being added, the excess material not required for that cross section is being cut away. LOM is one of the fastest RP processes for parts with larger cross-sectional areas, which makes it ideal for producing larger parts. Figure 9.1 shows a LOM 1015 system.
