Laser forming, a technique that emerged in the 1980s, is a fabrication method that uses a laser to fold metal sheets into 3D structures. However, similar to challenges found in designing and fabricating foldable structures, laser forming is only capable of folding simple structures with few crease lines, as designing foldable shapes with tens or even hundreds of crease lines has been prohibitively tedious. Origami is another old practice in making foldable structures, inspiring new research topics such as folding with active material and self-folding robots. Following origami design principles, where the 2D design can be a simple polygon with crease lines or a graph or tree-structured pattern with cuts or holes which are called polyhedral nets, laser forming can be used to cut and fold such 2D sheets into various 3D objects. This research establishes the first computational foundation for laser forming fabrication using the modeling of polyhedral nets. Specifically, I make three main contributions throughout the dissertation. 1) Propose an efficient optimization framework that combines the evaluation of motion planning and the generation of crease pattern designs to create foldable nets, which benefits not only the laser forming designs but also finding polyhedral nets with any motion constraints. 2) Design a sophisticated motion planning algorithm based on outside-in folding to tackle the technical challenges of model self-intersection, laser visibility occlusion, and the substrate collision with the net, and a dual-laser solution to fabricate non-convex shapes. 3) For fabricating increasingly complex models, consider incorporating computationally expensive heat simulation into the loop of motion planning to ensure the heat generated by the laser does not severely deform the substrate while not over-delaying the folding process. In addition, this dissertation concludes with the development of an interactive CAD tool to help the users quickly modeling their design for fabrication while conforming with the constraints of laser forming, with a prospect of future researches such as laser-formable net surgery and laser-forming kirigami.
