Laminated Object Manufacturing (LOM)

Posted by TierTime on 5. Jan 2012

Laminated Object Manufacturing (LOM) is a rapid prototyping system developed by Helisys Inc. (Cubic Technologies is now the successor organization of Helisys) In it, layers of adhesive-coated paper, plastic, or metal laminates are successively glued together and cut to shape with a knife or laser cutter.

The process is performed as follows:

1.Sheet is adhered to a substrate with a heated roller. 2.Laser traces desired dimensions of prototype. 3.Laser cross hatches non-part area to facilitate waste removal. 4.Platform with completed layer moves down out of the way. 5.Fresh sheet of material is rolled into position. 6.Platform moves up into position to receive next layer. 7.The process is repeated.

Because of low accuracy, limited material range and low material utilization rate (roughly 20%), LOM has been gradually given up by most manufacturers.
