Using a laser in a non-contact process to form metal sheet and other materials. The forming process is progressive (at about 2-3 degrees per pass). The material here is steel sheet, about 2-3 mm thick. Within a minute or so, the sheet has been bent to a 90 degree angle along a single fold line - 2D laser forming. The process depends on a steep thermal gradient being established between the top and bottom surfaces of the sheet. However, there is no thermal damage to the material.
