LaserStacker: Fabricating 3D Objects by Laser Cutting and Welding
summary
System uses a standard laser cutter to cut through stacked acrylic sheets and weld their interfaces in one run, producing ready-assembled 3D parts (scissors, gears, pinball, architectural models) with moving elements. Four core operations are cutting, welding, release, healing; release isolates surplus welds, healing refuses undesired cuts by refilling gaps. Tested with up to 24 mm stacks, ~1 mm minimum layer thickness, 2.5×2.5 cm welds hold >15 kg. Workflow exports from SketchUp plugin to color-coded SVG paths and tuned speed settings via a 27-point curve fit.
