Accretor (2012) is a computer program that is based on accretion of particles (small cubical grains: voxels) to grow very detailed sculptures.
The process starts with a random clump of a few particles. Particles are then added until a certain size is reached, with the final object consisting of millions of particles. Rules decide if a new particle can be added to a certain place on the surface of the existing form, depending on the configuration of the particles nearby. By 3D printing the designs, the entire process from design to execution is automated: the industrial production of unique artefacts.
A first series of Accretor sculptures are produced in 2012 (a second series in 2013) with 3D printing of acrylic. The objects differ in size, approximately 15 x 15 x 15 cm., and they consist of
8 to 12.5 million particles each.
