Kayser is interested in the use of natural resources in 3D printing. Experiments with solar power led him to the desert and to the two elements most readily available there: sun and sand, whose silica component solidifies as glass when heated to its melting point and allowed to cool. Kayser tested his first manually operated solar 3D-printing machine in 2011 in the Moroccan desert. He completed a bigger, fully automated, computer-driven version called SolarSinter later that year and tested it in the Sahara. This bowl was produced by the SolarSinter.
