Abstract: A pressurized consolidation assembly for an additive manufacturing system is provided. The pressurized consolidation assembly defines a first direction, a second direction, and a third direction, the three directions orthogonal to each other. The pressurized consolidation assembly includes a build platform configured to hold a plurality of particles and a pressure chamber surrounding the build platform. The pressure chamber is configured to retain a first volume of a gas having a first pressure. The pressure chamber includes an energy beam window. The energy beam window extends through a first section of the pressure chamber and is configured to enable an energy beam to pass through the energy beam window to be incident on the plurality of particles on the build platform.

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.
