Title:
付加製造制御システム
Document Type and Number:
Japanese Patent JP7097391
Kind Code:
B2
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.
