Abstract: Systems and methods for reducing charged powder particle scattering in powder-bed fusion (PBF) systems are provided. A PBF apparatus can include a structure that supports a layer of powder material having a plurality of particles of powder. For example, the structure can be a build plate, a build floor, a build piece, etc. The apparatus can also include an energy beam source that generates an energy beam and a deflector that applies the energy beam to fuse an area of the powder material in the layer. The energy beam can electrically charge the particles of powder. The apparatus can also include an electrical system that generates an electrical force between the structure and the charged particles of powder. For example, the electrical system can include a voltage source that applies a first voltage to the structure.

Abstract: Wheel assembles using integrated motors and speed reducers for electric vehicles are disclosed for providing improved structural efficiency. A wheel assembly may include a motor for providing power to a wheel, a leading or trailing type or similar suspension link, a caliper mounted to the suspension link and configured to engage a friction brake rotor on the wheel, and a synchronous belt mounted off-axis for implementing speed reducing. In certain embodiments, the respective components of the wheel assembly are nested to fit into a minimal volume. In other embodiments, the wheel assembly includes a motor that is not nested and that is configured to supply power to the wheel via a belt and pulley system.

Abstract: Techniques for optimizing powder hole removal are disclosed. In one aspect, an apparatus for inserting powder removal features may identify what powder removal features are optimal for a given AM component, as well as the optimal location and physical characteristics of these features. The features are automatedly added to the component, and an FEA test is run. In the event of failure, the offending feature is removed and the process is repeated. If successful then the loose powder may be removed in a post-processing step following AM.

Abstract: Techniques for structurally integrated heat exchangers are presented herein. A heat exchanger in accordance with an aspect of the present disclosure comprises a structure configured to enclose a volume for storing a first fluid, and to connect to a load. The heat exchanger further comprises a first and a second header first arranged in opposing inner walls of the structure. The heat exchanger further comprises one or more load-bearing struts extending to connect the first and second headers within the volume and configured to pass a second fluid through the volume for transferring heat to the first fluid, the second fluid configured to cool a different component in the vehicle.

Abstract: Systems and methods for multi-materials and varying print parameters in Additive Manufacturing systems are provided. In one example, a layer including a first powder material and a second material different from the first powder material are deposited, such that at least a first portion of the first powder material is in a first area that is devoid of the second material. An energy beam is generated and applied to fuse the layer at a plurality of locations. In another example, a layer of a powder material is deposited based on a first subset of parameters. An energy beam is generated based on a second subset of the parameters, and the energy beam is applied to fuse the layer at a plurality of locations based on a third subset of the parameters. At least one of the parameters is set to have different values during a slice printing operation.

Abstract: Systems and methods for control in additive manufacturing systems are provided. A powder-bed fusion apparatus can include an energy beam source that generates an energy beam and a deflector that applies the energy beam to fuse powder material to create a 3-D object based on an object model. The system can also include a characterizer that obtains information relating to fusing the powder material. The characterizer can be a sensor that measures the shape of the object, a processor that determines a physics-based model of the object, etc. The system can also include a comparator that determines a variation from the object model based on the information, and a compensator that modifies the application of energy to the powder material based on the variation. For example, applied energy can be increased in areas that require higher energy to completely fuse powder material, such areas of thicker powder layer.

Abstract: Systems and methods of support structures in powder-bed fusion (PBF) are provided. Support structures can be formed of bound powder, which can be, for example, compacted powder, compacted and sintered powder, powder with a binding agent applied, etc. Support structures can be formed of non-powder support material, such as a foam. Support structures can be formed to include inductive components that can be used to facilitate removal of the support structures in the presence of an external magnetic field. Additionally, support structures can be formed to break when a fluid, such as air or water, creates a force and/or pressure at a connection point interface.
