The PERCY STOOLS are a series of algorithmically designed and 3D printed furniture. Each individual stool is uniquely generated by an algorithmic design process and 3D printed with an industrial robot.

 

Each piece is generated algorithmically based on a standardised form. A combination of strict and loose rules combine to create tool paths for the robotic 3D printer to follow. The strict rules on the outside of the piece maintain the products topology while the loose rules on the inside add visually striking but still functional elements to the furniture. The final form is given by the robotic 3D printer, allowing for unique intricacies and emergent behaviour. The stools are made from PLA (Polylactic Acid), and weight ~5-6kg each. This gives the stools a weighty and solid feel.

 

The combination of algorithmic design and robotic fabrication showcases the possibilities that are opening up to Industrial Designers.

 

These pieces were the result of a design research project (under the supervision of Scott Mayson) undertaken for the honours component of the Bachelor of Industrial Design (Honours) at RMIT University, Melbourne, Australia. This research project explored the algorithmic design process within the Industrial Design field, through the lens of furniture design and a focus on additive manufacturing and robotic fabrication.

 

The robotic 3D printer is a system that combines a Kuka KR150 robotic arm with a plastic granule extruder capable of Xkg/h and a wide variety of plastics, in it's current setup the extruder uses PLA. It is currently capable of producing parts up to 3m x 2m x 1.5m. It was setup by Ryan Pennings as part of his research project and is housed in the RMIT Design Hub, Melbourne, Australia as part of the RMIT School of Architecture and Design. It is a collaboration between Ryan Pennings, RMIT School of Architecture and Design, and industry.
