Strange Attractors

Home-how they are made

The calculated data from Chaoscope of a strange attractor makes a pointcloud. The pointcloud is triangulated into a mesh. Because of the selfintersecting nature of the most strange attractor shapes,
this mesh displays many defects wich are repaired by manual reverse enginering.

SLS is a technique by which parts are built layer by layer with a layer thickness about 0,1 mm.
The basic material consists of polyamide powder with particle sizes in the order of magnitude of 50 µm.
Successive powder layers are spread on top of each other. After deposition, a computer controlled CO2 laser beam scans the surface and selectively binds together the powder particles of the corresponding cross section of the product. During laser exposure, the powder temperature rises above the glass transition point after which adjacent particles flow together. This process is called selective laser sintering.

Alumide is a blend of aluminium and polyamide powders, which allows metallic-looking, non-porous components to be machined easily and is resistant to high temperatures.

For bronze casting each object is printed with a support material by a 3d printer in a resin. Due to the
shape of most strange attractors it is impossible to work with a mould.
After removing the support, the object is put into a cuvette and filled up with a ceramic-plaster mixture.
The cuvette is put into a oven where the plastic object incinerates.
In a vacuum environment the cuvette is casted up with bronze. Because of the vacuum environment
it is possible to cast objects with a very thin wallthickness of about 1,5 mm.
