SYSTEMS AND METHODS FOR POWDER BED DENSITY MEASUREMENT AND CONTROL FOR ADDITIVE MANUFACTURING

摘要

Systems and methods are disclosed for forming a three-dimensional object using additive manufacturing. One method includes depositing a first amount of powder material onto a powder print bed of a printing system, spreading the first amount of powder material across the powder print bed to form a first layer, measuring a density of powder material within the powder print bed, and adjusting a parameter of the printing system based on the measured density of the powder material within the powder print bed.
