Abstract: A device (1) for spinning a 3D printed workpiece (100). The device has a rotor (2) for spinning about a spinning axis (A) and a receptacle (8) for holding the workpiece (100). The receptacle (8) is pivotally attached to the rotor (2) for swiveling about a swivel axis (B) that is transverse to the spinning axis (A). The pivotal attachment enables swiveling of the receptacle (8) between a first angular orientation relative to the spinning axis (A) and a different second angular orientation relative to the spinning axis (A). The device (1) further has a balancing weight (9) that is movably arranged relative to the receptacle (8). The balancing weight (9) is lockable at different distances relative to the receptacle (8).

Abstract: A method of building up a physical object by additive manufacturing which has the steps of building up the object and at least one support structure layer by layer along a build axis. The support structure supports the object relative to a build platform. During building up the object and the at least one support structure a connection is provided between the support structure and the object by a plurality of layers each of which being a common layer of the object and the support structure.
