The intra-processing component calculates required power for the beam at intervals and events on the beam path based upon the additive-path-with-geometry-metadata and calculations of the energy balance at the melt pool and the total energy for each point P(s) on the path.

Abstract: A seat blocking system can comprise a seat. The seat can include a seat understructure and an overlying seating surface. The seat understructure can form a seat base and a seatback arranged in a seating configuration. The seating surface can be configured to morph between a sittable shape, in which the seating surface is coextensive with the seat understructure, and an unsittable shape, in which the seating surface is expanded over at least a portion of the seat understructure.
