Winning the 2012 SCI-Arc’s Gehry Prize with their masters thesis project, Liz and Kyle von Hasseln have designed a unique 3D printing method developed in the SCI-Arc Robot House. Developed in cooperation with advisers Devyn Weiser and Peter Testa, the couple’s Phantom Geometry allows designers to make alterations to the design while it’s being printed, using an UV light projector, a special photo-sensitive resin and controlled robotic arms.
Project description from the architects:
This work is centered on the development of a system for generating material volume from streaming information. The system uses UV light from a modified DLP projector to continuously and selectively cure photo initiated resin within a shallow vat system we developed for the project. The cured part is simultaneously and continually pulled away from the vat, allowing un-cured resin to flood in beneath it to be subsequently cured. The result is the material reification of streaming data that emerges along the motion path of the Stäubli robot maneuvering the vat/projector apparatus.
This system of fabrication relies upon native real-time feed-back and feed-forward mechanisms, and is therefore interruptible and corruptible at any time. The streaming data input may be transformed or modified at any time, and such interventions impact emerging downstream geometry.
