Personal fabrication is currently a one-way process: Once an object has been fabricated with a 3D printer, it cannot be changed anymore; any change requires printing a new version from scratch. In this paper, we propose a different approach: instead of re-printing the entire object from scratch, we suggest patching the existing object and replacing only the unsatisfactory parts. This saves material and reduces waste, making a first step towards more sustainable 3D printing.
This project is a collaboration between Hasso Plattner Institute and Cornell University.
