Lately, there’s been plenty of progress in 3D printing objects from the lunar regolith. We’ve reported on several projects that have attempted to do so, with varying degrees of success. However, most of them require some additive, such as a polymer or salt water, as a binding agent. Recently, a paper from Julien Garnier and their co-authors at the University of Toulouse attempted to make compression-hardened 3D-printed objects using nothing but the regolith itself.
