The broad availability of 3D-printing enables end-users to rapidly fabricate personalized objects. While the actual manufacturing process is largely automated, users still need knowledge of complex design applications to not only produce ready-designed objects, but also adapt them to their needs or even design new objects from scratch.

In this project, we explore an AI-powered system that assists users in creating 3D objects for digital fabrication. For this, we use natural language processing (NLP) to enable users to describe objects using their natural language (e.g., “A green rectangular box.”). In this micro project, we conduct a Wizard-of-Oz study to elicit the requirements for such a system. The task of the participants is to recreate a given object using a spoken description with iterative refinements.
