LaserStacker:
Fabricating 3D Objects by Laser Cutting and Welding

The key idea of LaserStacking is to use the laser cutter to not only cut but also to weld. Users place not one acrylic sheet, but a stack of acrylic sheets into their cutter. In a single process, LaserStacker cuts each individual layer to shape (through all layers above it), welds layers by melting material at their interface, and heals undesired cuts in higher layers. When users take out the object from the laser cutter, it is already assembled. [...]

In Proceedings of UIST '16 (Full Paper).

Such metamaterial mechanisms consist of a single block of material the cells of which play together in a well-defined way in order to achieve macroscopic movement. Our metamaterial door latch, for example, transforms the rotary movement of its handle into a linear motion of the latch. [...]

Handmade Jewelry made from Silver, Wood and Tin






I create thoughtfully handmade jewelry, often elegant, sometimes geeky. I like to work with natural materials and shapes; frequently creating necklaces, rings and emblems.
