Abstract: A 3D printing system (10) for manufacturing at least one physical object comprises at least one reservoir (12) for receiving hardenable material; at least one light engine (22) configured to irradiate light onto a focal plane within the reservoir of the hardenable material to form a layer of hardened material; at least one build platform (18) for carrying the physical object to be manufactured; and a controller configured to select at least one or at least two optical resolutions from two or more optical resolutions available in the 3D printing system for irradiating the hardenable material based on a predetermined surface quality of the physical object to be manufactured.

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).
