Machine Sensibility: Unpacking the Embodied and Situated Dimensions of 3D Printing.

This paper offers a conceptual contribution to understand 3D printing practice. We have studied conversations between 3D printing practitioners who discuss failed and discarded printed artifacts and analyzed how they make sense of the printing process. Based on findings of interactions with the machine itself, materials used, and designs applied, this study contributes to the field of HCI by highlighting the embodied and situated dimensions of 3D printing. Introducing the concept of machine sensibility, we characterize our findings around: i) assessing printability, ii) monitoring and intervening and iii) reading the prints. We use the term machine to highlight the importance of understanding the materiality of the 3D printer, and sensibility, to address critical interactions and abilities that surfaced in studying this practice. The concept allows researchers to put 3D printing practice in the context of contemporary interaction design research and helps to understand challenges of material-machine-design interdependencies.
