A new approach therefore looks at utilising the 3D printer for the nodes only which will then be connected with standard metal or perspex rods. A complex procedural model based on a series of Boolean operations has been set up within the animation software Houdini which hollows out the nodes and generates the muffs for inserting the connecting rods automatically as the particles travel on their unique paths.

Research
started during my IASPIS residency
looked at Particle systems as a
potential design tool for architecture.

This resulted in the computer animation 'Digital Fluidity',


which was followed by a series of images for an architectural intervention within the area of the K3 cafeteria;


and, in 2000, the video sequences and art installation 'Northwestwind - Mild Turbulence' was exhibited at the Darren Knight Gallery in Sydney during the Olympics.

In contrast to traditional design methods particle systems have the potential to generate a more 'natural' irregularity as their movement through space is guided by simple laws of physics. Each particle has specific attributes such as velocity, mass and a life expectancy which determine its behaviour within an environment. The environment in return acts on the particle through gravity, wind, turbulence etc. In the examples shown here further irregularity is added by copying self-similar shapes to the position of the particles ensuring that no two shapes are the same size or oriented in the same direction. Thus traditional production techniques - based on standardized elements fail, calling for automated fabricators such as the StrataSys 3D printer.


Initial attempts at printing out the designs with the StrataSys showed current limitations of the technology - one being the relatively small output size, the other the high material cost.
