Abstract
3D printing of mineral foams is a novel technology where the changes in material properties during and after fabrication affect the final geometry. These changes need to be quantified with sensing techniques in order to increase the process robustness for fabricating custom-shaped building components. In this paper, camera tracking and 3D scanning are studied to improve the dimensional accuracy of 3D printed foam prototypes.
