Abstract:
A method, medium, and system to receive a specification defining a model of a part to be produced by an additive manufacturing (AM) process; execute an AM simulation on the model of the part to determine a prediction of thermal distortions to the part; execute a topology optimization(TO) to create TO supports that counteract the predicted thermal distortions; generate at least one rule-based support based on a geometry of the part to interface with the part at one or more regions other than the TO supports; combining the TO supports and the at least one rule-based support to generate a set of hybrid supports; save a record of the set of hybrid supports; and transmit the record of the set of hybrid supports to an AM controller to control an AM system to generate a support structure for an AM production of the part.
Abstract:
A component (200, 300) formed by an additive manufacturing process includes a body (206) and a first vibration damper (210, 216, 306, 308). The body (206) is formed from an additive manufacturing material, and defines at least a first cavity (202, 204) completely enclosed within the body (206). The first vibration damper (210, 216, 306, 308) is disposed within the first cavity (202, 204). The first vibration damper (210, 216, 306, 308) includes a flowable medium (214) and a first solidified element (212) formed from the additive manufacturing material. The flowable medium (214) surrounds the first solidified element (212).
Abstract:
A method, medium, and system to execute an additive manufacturing (AM) simulation on a model of a part; determine, based on the AM simulation, a prediction of a temperature and displacement distribution in the part at a particular time in the AM process; apply the predicted temperature and displacement distributions in the part as a boundary conditions on a support design space to determine a temperature distribution throughout the support design space; and execute a thermal-structural topology optimization based on the determined temperature and displacement distributions throughout the support design space to determine a distribution of material in the design space for a thermal support structure to interface with the part that optimally reduces a thermal gradient in the part with a minimum of material and results in the generation of an optimized AM support structure.
Abstract:
An additive manufacturing system includes a laser device, a build plate, and a scanning device. The laser device is configured to generate a laser beam with a variable intensity. The build plate is configured to support a powdered build material. The scanning device is configured to selectively direct the laser beam across the powdered build material to generate a melt pool on the build plate. The scanning device is configured to oscillate a spatial position of the laser beam while the laser device simultaneously modulates the intensity of the laser beam to facilitate reducing spatter and to facilitate reducing a temperature of the melt pool to reduce overheating of the melt pool.
