A regular laser cutter is used to cut outlines of objects in clear lexan, then, by unfocusing the laser it slowly melts the bend lines, causing the lexan to fold and then solidify into a solid joint.

The idea is very simple, laminate a photograph onto some laser-cuttable board, and then run the laser over the outline of the pieces ... Once you’ve got the puzzle cut out, you can seal up ...

Laser cutting is the use of a high-powered laser ... The second colour should be used if you want to engrave sharp lines or outlines into the material. This is called 'vector engraving'.
