1. A method of building up at least a first and a second physical workpiece from a first light hardenable material on a 3D printing device that comprises at least a first build platform, the method comprising the steps of:
providing to the 3D printing device a first dataset for building up a first workpiece, the first workpiece comprising a first object and a first support structure, the first support structure supporting the first object during building up;
starting a first print job based on the first dataset, wherein the first print job comprises layerwise printing of the first workpiece from the first light hardenable material on the first build platform in a dimension along a build axis, wherein the first print job further comprises layerwise printing an auxiliary base at a position laterally of the build axis during printing of the first workpiece;
providing to the 3D printing device a second dataset for building up a second workpiece after the start of the first print job, the second workpiece comprising a second object and a second support structure, the second support structure supporting the second object during building up and including a planar interface to the auxiliary base; and
starting a second print job based on the second dataset before finishing the first print job, wherein the second print job comprises layerwise printing of the second workpiece from the first light hardenable material.
