  • Patent number: 10525629
    Abstract: An additive manufacturing (AM) system comprising a process distortion compensation computing system configured to determine a digital nominal model that represents a physical target object excluding a distortion, and a digital distortion model that represents the physical target object including at least one distortion. The AM system further comprises an AM peripheral device configured to form a three-dimensional physical object based on a digital compensation model. The process distortion compensation computing system determines a material volume difference between the digital nominal model and the digital distortion model, and generates the digital compensation model that compensates for the material volume difference.

  • Publication number: 20190377843
    Abstract: An additive manufacturing (AM) system includes a process distortion compensation computing system and an AM peripheral device. The process distortion compensation computing system determines a digital nominal model that represents a physical target object excluding a distortion, and a digital distortion model that represents the physical target object including at least one distortion. The AM peripheral device forms a three-dimensional (3D) physical object based on a digital compensation model. The process distortion compensation computing system also determines a digital skeletal model indicating a predicted change in at least one of the shape and volume of the nominal model, and generates the digital compensation model based on the skeletal model that compensates for the at least one distortion.

  • Patent number: 9869006
    Abstract: This invention disclosed a method for preparing the ultrafine intermetallic particles reinforced metal matrix composites (MMC). The particle size of ultrafine intermetallic particles is about 0.01˜5 ?m. In this method, intermetallic particles and metal matrix were first ball milled together to get the mixed powder. Then, powders were cold-pressed then vacuum melting with metals to prepare the reinforced metal matrix composites materials. The intermetallic particles addition amount in this is 1˜30 wt %. This invention improve the dispersion properties of intermetallic particles while increase the particle/matrix interface strength. The ultrafine intermetallic particles reinforced MMC shows the very good performance with good ductility and strength.
