Laser Lamination 3d Printing

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.

Laser lamination 3d printing.

Sheet lamination is one of the seven recognized 3d printing methods. Selective laser sintering sls sls 3d printing technology originated in the late 1980 s at the university of texas at austin. If the previous fixes did not improve your prints try slowing your print speed in 10mm sec increments. Laminated object manufacturing lom is a method of 3d printing.

Basically the process uses lasers to sinter or coalesce powdered material layer by layer to create a solid structure. During the lom process layers of plastic or paper. If the print head is moving too fast the extruding plastic will not have time to successfully bond to the previous layer. Sheets of material are bonded together and cut in the right geometry according to the 3d model.

Laminated object manufacturing lom is a rapid prototyping system developed by helisys inc. It is considered additive because one sheet of material is bound to another in a layer by layer process. 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. Laminated object manufacturing or lom is a very fast and inexpensive way to 3d print objects in several kinds of materials.

3d print layer separation can be caused by high print speeds. 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. Over the years this technology has experienced remarkable advances. 3d printing and laser technology go hand in hand.

What is sheet lamination 3d printing. 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.
