In “interactive fabrication the interfaces help the operator to manufacture what he, she imagines more effectively, by giving him, her access to new tools to design more freely and closer to the manufacturing process.

The expected work will define the types of information to be communicated (follow-up, safety, etc.) and the interaction tools (helmet, watch, bracelet, etc.) going beyond the current framework of rapid prototyping to implement it in manufacturing. For short, we produce interfaces for direct interaction during the execution of an industrial additive manufacturing process to improve the fabrication by allowing

the operator to monitor the apparition of manufacturing issues and react in real time. Interactive Fabrication aims to blend manufacturing and design by fitting perfectly into Milgram's augmented reality continuum by allowing either interaction with a real object to modify a digital model, or by modifying the digital model to modify the manufacturing. Zoran, A. and Paradiso, J. in CHI’2014, indicate that Interactive Fabrication can then be seen as a form of hybrid craft allowing interactive, rapid and intuitive manufacturing. By bringing the design and manufacturing processes together, Interactive Fabrication allows the design process to be integrated directly into the manufacturing scene. Finally, Interactive Fabrication can be seen as the continuum between industrialization and craft. A point not yet addressed is the way in which the manufacturing information is provided to the user by the system. This is what we are exploring in augmenting (in the sense of augmented reality) the Manufacturing Interactive environment with various sensory modalities

(visual, audio, tactile).

The evolution and maturity of additive manufacturing processes has enabled the construction sector to be invested. However, many questions remain unanswered: how to modify the formulation to take into account the variability of raw materials (variable water content of aggregates, variable composition of excavated soil, sediments, etc.) and also the variability of the implementation conditions (temperature, humidity, wind speed)? How to define the formulation that meets the usual expectations of mechanical resistance? What filling strategy? What rheology and solidification are compatible with additive manufacturing? Finally, how can the process be controlled so that it meets the above quality criteria? We tackle issues of the adaptation of two construction

materials for additive building: the low clinker concrete and the raw earth. We are interested by the development of real-time monitoring of fresh material properties with appropriate instrumentation and the improvement of human-system interaction
