What Is Laminated Object Manufacturing?

Laminated Object Manufacturing (LOM) is formed by bonding boxes or papers with adhesive on the back to each other. As shown in the figure, a paper roll coated with hot melt adhesive on one side is sleeved on a paper roll, and is wound around a take-up roll across a support roll. The same service motor drives the take-up roller to rotate, so that the paper roll moves a certain distance in the direction indicated by the arrow in the figure. The table rises to contact the paper surface, and the hot-pressing roller rolls from right to left along the paper surface, heating the hot-melt adhesive on the back of the paper, and bonding this layer of paper to the previous layer of paper on the substrate. The laser beam emitted by the CO 2 laser tracks the 2D cross-section profile data of the part for cutting, and cuts the waste paper material outside the outline into square cells to facilitate peeling after the forming process is completed. After each section is cut, the worktable and the cut-out contour layer are automatically lowered to a certain height, and the next working cycle is repeated until a three-dimensional paper prototype part is formed with a layer-by-layer cross-section. Then peel off the small squares of waste paper to get "paper-like products" that behave like hardwood or plastic. [1]
