The World's Smallest Jigsaw Puzzle Piece

Posted by timothy on from the lost-behind-couch dept.

An anonymous reader writes "Scientists from the Laser Zentrum Hannover used a femtosecond laser to make what is probably the world's smallest jigsaw which will be shown at the Hannover Messe. Its size is 5mm x 5mm and it consists of 100 parts. It's supposed to demonstrate the precision with which femtosecond lasers can cut materials without burning or damaging them. (Closeup 1, Closeup 2)"

    or is 5mm not really very small?

    (also..fp! heh)

    That is indeed a small puzzle, but...

    why did they make all the pieces almost 100% alike? Jigsaw puzzles aren't supposed to have interchangeable pieces. Each piece should be somewhat unique.

    Well, not all is lost... at least the pieces seem to have a little texture...

  3. Depth? by cornjchob · · Score: 4, Insightful

    OK, it can cut through paper with that accuracy and didn't destory it--I'm impressed. However, how deep would a laser like this be able to penetrate before it would be rendered impotent/would start destroying the material? Or isn't that relevant because of the apps this would be used in?
