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.
