The present disclosure generally relates to powder packing for additive manufacturing (AM) methods and systems. Conventional powder packing methods are manual and non-standardized, and they result in operator fatigue and potentially product inconsistencies. Powder packing according to the present disclosure improves standardization and reduces turnaround time, with the potential to lower the cost of AM.

This shaping apparatus is equipped with: a movement system which moves a target surface; a measurement system for acquiring position information of the target surface in a state movable by the movement system, a beam shaping system that has a beam irradiation section and a material processing section which supplies a shaping material irradiated by a beam from beam irradiation section; and a controller. On the basis of 3D data of a three-dimensional shaped object to be formed on a target surface and position information of the target surface acquired using the measurement system, the controller controls the movement system and the beam shaping system such that a target portion on the target surface is shaped by supplying the shaping material while moving the target surface and the beam from beam irradiation section relative to each other.

A method for large-scale, real-time simultaneous additive and subtractive manufacturing is described. The apparatus used in the method includes a build unit and a machining mechanism that are attached to a positioning mechanism, a rotating platform, and a rotary encoder attached to the rotating platform. The method involves rotating the build platform; determining the rotational speed; growing the object and the build wall through repetitive cycles of moving the build unit(s) over and substantially parallel to multiple build areas within the build platform to deposit a layer of powder at each build area, leveling the powder, and irradiating the powder to form a fused additive layer at each build area; machining the object being manufactured; and cutting and removing the build wall. The irradiation parameters are calibrated based on the determined rotational speed.
