Abstract: A system and method are described for post-processing a 3D printed component. For example, support structures for the 3D printed component may be removed during post-processing. In the system and method, a marker is placed on the 3D printed component or on a support structure attached to the 3D printed component. The marker may be printed while the 3D printed component and the support structures are printed by a 3D printer. After printing, the marker may then be sensed to determine one or more cutting paths between the 3D printed component and the support structures. The 3D printed component may then be autonomously separated from the support structures by cutting through the cutting path.

Abstract: An electrical switch assembly (10) comprises a contact element (14, 18) to be moved towards a further contact element (14, 18) for generating an electrical connection; and a drive (16) for moving the contact element (14, 18); wherein the drive (16) comprises a plunger (26) with a connection member (30) interconnected with the contact element (14); wherein the plunger (26) comprises a mechanical structure (34) with a top side (36) to which the connection member (30) is connected, and a bottom side (38) opposite to the top side (36); wherein the drive (16) comprises a Thomson coil (52) for moving the plunger (26) via an electrically conducting top face (48), which is provided on the top side (36) and an electrically conducting bottom face (50), which is provided on the bottom side (38). The mechanical structure (34) comprises at least one channel between the top side (36) and the bottom side (38), the at least one channel extending transverse to a movement direction (D) of the plunger (26). Furthermore, the mechanical structure (34) fills less than 50% of a volume between the top side (36) and the bottom side (38).

Abstract: A system and method are described for post-processing a 3D printed component. For example, support structures for the 3D printed component may be removed during post-processing. In the system and method, a first image of a component is stored in memory. A second image of a 3D printed component corresponding to the component is also captured. One or more cutting paths between the 3D printed component and the support structures is then determined based on the first image and the second image. The 3D printed component may then be autonomously separated from the support structures by cutting through the cutting path.

Abstract: The invention relates to a two-phase heat transfer device (10) for dissipating heat from a heat source, for instance a power semiconductor module (26), by a heat transfer medium, wherein the two-phase heat transfer device (10) comprises a main body (12), wherein the main body (12) is formed by a body material (14) and comprises a multi-dimensional void network (16), wherein the multi-dimensional void network (16) comprises voids and is adapted for containing the heat transfer medium, wherein the multi-dimensional void network (16) is adapted such that a flow of the heat transfer medium along a path (20) through the main body (12) is based on a variation in capillary action exerted by the multi-dimensional void network (16) on the heat transfer medium along the path (20). Further the invention relates to a power semiconductor module (26) comprising the above two-phase heat transfer device (10) for heat dissipation and to a method for producing the above two-phase heat transfer device (10).

Abstract: A system and method are described for post-processing 3D printed components. Post-processing may include removing support structures for the 3D printed components and may also include other processes like assembling 3D printed components into finished products. In the system and method, post-processing strategies are iteratively generated and performed on 3D printed components. Performance metrics of the post-processing strategies are compared with a user-defined performance indicator in a learning process to improve the post-processing strategy over a number of 3D printed components.

Abstract: The present invention relates to high-resistivity permanent magnets, their preparation and their application in electrical machines. A permanent magnet according to the present invention comprises a permanent magnet comprising a magnetic material and a shaped inorganic insulating element, wherein a shape and a size of the shaped inorganic insulating element have been substantially unchanged by the sintering, wherein the shaped inorganic insulating element has a width and a length which are both at least 10 times larger than an average grain diameter of the magnetic material after sintering, and wherein an arithmetic average waviness Wa of an interface between the magnetic material and the shaped inorganic insulating element is less than 10% of a local wall thickness of the shaped inorganic insulating element after sintering.
