Accretor

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 seed of a few 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. Many rules are possible and the system can generate these rules automatically. But not all rules will create a coherent structure: a form that can be materialised. Therefore the system only applies rules that yield a workable form. The designs are made of acrylic resin by using 3D printing techniques. The whole 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 the multi-material 3D printing technique. This rapid manufacturing technique creates 3-dimensional objects by printing two resins simultaneously, one to support the object during the printing and one to create the object. After the print is ready the support resin is removed with water. The objects differ in size, approximately 15 x 15 x 15 cm., and they consist of 8 to 12.5 million particles each.
