May 20 2020 by leslie langnau leave a comment one of the lesser known 3d printing technologies is sheet lamination sometimes also known as laminated object manufacturing lom. Selective laser sintering sls sls 3d printing technology originated in the late 1980 s at the university of texas at austin. Sheets of material are bonded together and cut in the right geometry according to the 3d model. 3d printing and laser technology go hand in hand.

The process uses sheets of building material which are cut through laser or knife and the sheets are joined one after the other either by using an adhesive or by wielding the laser cut sheets together to form the 3d object. What is sheet lamination 3d printing. Basically the process uses lasers to sinter or coalesce powdered material layer by layer to create a solid structure. Lens laser engineered net shaping which was developed by sandia national labs is one example of the powder fed directed energy deposition process for 3d printing or restoring metal parts.

Laminated object manufacturing or lom is a very fast and inexpensive way to 3d print objects in several kinds of materials. If the previous fixes did not improve your prints try slowing your print speed in 10mm sec increments. 3d print layer separation can be caused by high print speeds. Laminated object manufacturing lom is a rapid prototyping system developed by helisys inc.

It was developed by the california based helisys inc. Over the years this technology has experienced remarkable advances. Sheet lamination is one of the seven recognized 3d printing methods. 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 objects printed with this technique may be additionally modified by machining or drilling.

Sls also known as selective laser sintering is a special method that employs a process called powder bed fusion to create 3d objects. Laminated object manufacturing is mainly used for rapid prototyping processes not for production.
