Laser-sintered chair.

Believe it or not, this plastic chair was made by laser-sintering plastic powder. Known as Osteon, the chair was built by taking horizontal slices through a 3D computer-aided design model. The resulting data was then used to drive a laser-sintering machine, which created the product by fusing successive layers of plastic powder. The virtual chair design was split into sections so that each could be grown within the 27.5 x 15 x 23 inch build envelope of an EOSINT P 700 laser-sintering machine. www.eos.info
