Constructable: Interactive Laser Cutting


Do you miss the old days of making things by hand, without the aid of a computer? Do you remember actually drafting drawings by hand? Well, the folks over at the Human-Computer Interaction group from the Hasso Plattner Institute have come up with a rather novel idea, combining manual input via laser pointers, to cut designs with a laser cutter. Sound familiar? A few days ago we shared another cool project on Laser Origami from the same people.

So what exactly is it? It’s an interactive drafting table which can produce very precise physical outputs from a rather imprecise input method. By using specific laser pointers, the user can instruct the laser cutter to cut, trace, or etch designs into the workpiece. A camera picks up the laser pointer and then the software cleans it up, by straightening lines, connecting the dots, etc. While only so much can be determined by the included video, it’s pretty impressive to see what the software comes up with while cutting the design… We can’t really imagine the programming behind it!

Between this and PACCAM: Interactive 2D Part Packing, it looks like laser cutting is going to get a whole lot more user friendly! Stick around after the break to see it in action, the results are quite impressive!
