Material: paper, aluminium, resin, bronze, tungsten carbide
Trees have the ability to add material where strength it is needed, and bones have the ability to take away material where it is not needed. With this knowledge the International Development Centre Adam Opel GmbH, a part of General Motors Engineering Europe created a dynamic digital tool to copy these ways of constructing used for optimizing car parts. In a way it quite precisely copies the way evolution constructs. We didn't use it to create the next worlds most perfect chair, but as a high tech sculpting tool to create elegant shapes with a sort of legitimacy. After a first try-out and calculation of a paper Bone Chair, the aluminium Bonechair was the first made in a series of 7. The process can be applied to any scale until architectural sizes in any material strength.
The following piece, a Chaise longue, was developed at the workshop of Vincent de Rijk, who is known for his expertise with resin and his architectural models for Rem Koolhaas. It is cast in a UV resistant clear poly urethan of shore 90. Soft enough to shape itself to your body.
Then we made a Rocking and Arm chair. They where cast in a home made recipe of marble powder and resin.
Both pieces are printed in a 79 (armchair) and 91 (rocker) part 3D mould assembled with countless little bolts.
Branch is cast in bronze, using a 3d printed polymer positive. And the
construction of the Bridge table (see below) is CNC milled from blocks of aluminium and
tabletop is made of unscratchable tungsten carbide, which is diamond
polished by a robot for over 300 hours.
All pieces were added to several public museum and private art collections. In the following link is a very nice text on bone furniture by David Dick
