A method of time-shifted and time-overlapping building up physical workpieces by additive manufacturing

A method of building up at least a first and a second physical workpiece from a 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;
• starting a first print job based on the first dataset, wherein the first print job comprises layerwise printing of the first workpiece on the first build platform in a dimension along a build axis;
• providing to the same 3D printing device a second dataset for building up a second workpiece after the start the first print job;
• 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;
• 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, and wherein the second workpiece is printed on the auxiliary base, the auxiliary base having a predetermined standardized shape.
