4.2.8 Leminated Object Modeling (LOM!
Laminated object modeling (LOM) was developed by Helisys Inc., and like SLA and
SLS, it was first offered commercially in the period from 1987 to 199(J. In LOM, the
laser is used to cut the top slice of a stack of paper that is progressively glued
together. After each profile has been cut by the laser (shown at the bottom right of
Figure 4.8), the roll of paper is advanced, a new layer is glued onto the stack, and the
process is repeated. After fabrication, some trimming, hand finishing, and curing are
needed. For larger components, especially in the automobile industry, LOM is often
preferred over the SLA or SLS processes.
