The LOM method uses material sheets (such as paper, plastic films or composite materials) as raw materials, and uses a carbon dioxide laser cutting system to cut out internal and external contours of the work pieces from the paper sheet coated with hot melt adhesive on the back according to the cross-sectional contour data extracted by the computer, while cross-cutting non-part areas to facilitate waste removal.
After cutting one layer, the feeding mechanism superimposes a new layer of paper sheets, and the worktable drives the formed work piece down (usually the thickness of the material is 0.1-0.2mm), and separates it from the belt-like sheet (material strip); The feeding mechanism rotates the receiving shaft and the feeding shaft to drive the material strip to move, so that the new layer moves to the processing area; the worktable rises to the processing plane; The paper-laying roller is hot-pressed, the number of layers of the workpiece is increased by one layer, and the height is increased by the size of the material thickness; then the section profile is cut on the new layer, and the parts are finally processed.
