Using a moving print bed for large-scale printing.
Phantom Geometry, winner of the new Gehry Prize thesis award, is a project by students from the Southern California Institute of Architecture. It was developed in the Robot House, a facility where students have acess to advanced robotic arms, under the guidance of Peter Testa and Devyn Weiser.
The original article on FastCo appears to suggest that the innovation in the project was to use a projector and UV cured resin to produce 3D prints. I hope that’s not what the prize was for, considering that this has been done several times already.
That confusion aside, this is a fascinating project. With typical UV resin 3D printing, the only movement of the print bed is to slowly lower, letting the project light cure one layer of resin at a time. In this case, both the print bed of resin and the projector are attached to robotic arms. This allows the machine to print structures many times larger than the print bed itself. It’s difficult to describe, so please watch the video.
