Experimental device machining is performed according to plan information including first type information indicating a first type condition of the experimental device machining and second type information indicating a second type condition of the experimental device machining. Third type information indicating a third type result and fourth type information indicating a fourth type result are acquired. Extended plan information is acquired in which a uniformity of extended second type information and extended third type information is equal to or greater than a threshold value. Extended third type information indicating a third type result and extended fourth type information indicating a fourth type result are acquired by performing the experimental device machining according to the extended plan information. An extended first relationship is derived that is a relationship between extended first type information, the extended second type information, and the extended third type information. An extended second relationship is derived that is a relationship between the extended first type information, the extended second type information, and the extended fourth type information. A model for estimating fourth type information indicating a fourth type result of actual device machining by receiving the second type information measured during the actual device machining and the third type information measured during the actual device machining and using the extended first relationship and the extended second relationship is generated. The model is output.

Additive manufacturing system includes one or more processors configured to determine one or more geometrical characteristics of each of multiple segments of a build part at a candidate position of the build part relative to an additive manufacturing instrument. The geometrical characteristics include an angle of incidence between a beam line extending from a beam emitter and a surface normal of a respective skin of the corresponding segment proximate to the beam line. The one or more processors select, based on the determined geometrical characteristics, a first set of beam parameters for forming a first segment of the build part and a second set of beam parameters for forming a second segment of the build part. At least one of the beam parameters in the second set differs from the beam parameters in the first set.
