Even though considered a rapid prototyping tool, 3D printers are very slow. Many objects require several hours of printing time or even have to print overnight. One could argue that the way 3D printers are currently operated is similar to the batch processing of punched cards in the early days of computing: all input parameters are pre-defined in the 3D modeling stage, the 3D printer then simply executes the instructions without human intervention. Since batch processing requires carefully thinking ahead, it is limited to expert users who can reason about the consequences of their design decisions.  

In the history of computing, moving away from batch processing enabled completely new interaction paradigms: while batch processing required carefully thinking ahead, command line input allowed for tighter feedback loops, and direct manipulation finally even enabled novice users to quickly iterate towards a solution. I believe repeating this evolution for the editing of physical matter will enable novice users to build objects only trained experts can build today. 

Progressing towards this goal requires advances in two areas: First, we need new design tools and interaction techniques for physical editing under computer control. Second, we need faster fabrication techniques to change physical matter in real-time after every editing step. In this talk, I present my research from the last four years as a first step to solve these challenges.
