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.

  1. Loss of mass? by sithkhan · · Score: 4, Interesting

    I used Google to translate the text, and nowhere is a mention of loss of mass mentioned. Given that these are small materials to begin with, how much mass is consumed in this process? The pics show pieces that are not snug. Just a thought ...

    the whole piece is 5 x 5 mm, approx. 3/16"
    the 100 pieces are said to be of dust grain size (now handle that - and don't you sneeze!).
    its extremely short pulses (1 Femtosec. = 10e-15 sec.) make this a great tool for cutting materials without damaging or burning them.

    I've done a couple of puzzles where EVERY piece is the exact same shape. You have to build the puzzle matching the picture. It makes it more difficult. I've also assembled puzzles upside down, not using the picture at all... You want to spend time cursing while building puzzles, try one of the 3-D ones.. This is impressive in my book. 100 pieces out of 5x5mm?
