a) Laminated Object Manufacturing (LOM) LOM is a highly integrated additive technology that can be used to produce accurate finishes, even though the stability of paper objects falls short of those manufactured using most RP techniques. The objects developed using LOM look very similar to wood. LOM technique can also be deployed on a vast range of materials, besides paper such as ceramics, metals, plastics and composites, but on a limited scope. A typical Laminated Object Manufacturing machines feature components such as portable mirror, heater roller, wastepaper take-up roller, paper feed roll and laser. The other critical operating apparatus includes smokestack and sealed chamber. Over the years, variations of LOM have also been developed by companies such as Mcor Technologies Ltd of Ireland, Helisys, Cubic Technologies and Solido 3D of Israel. The Mcor technology uses a knife in place of laser to cut and separate various 3D layers, before applying a bonding adhesive. The success of Mcor product is attributed to its low cost and excellent marketing strategies. Helisys, which was once a leading supplier …
