Abstract
Three-dimensional molding equipment includes powder supply equipment configured to supply powder material and form a powder layer, and a light beam scanning unit configured to radiate a light beam to the powder layer and move a radiated location thereof, where a three-dimensional shaped molding object is manufactured by alternately repeating processes of forming the powder layer and sintering the powder layer with light beam radiation. A region used for manufacturing the three-dimensional shaped molding object is divided into a plurality of divided regions such that respective divided regions have an equal-length molding path which is to be a scanning route of the beam such as having unequal-length molding parts by a scanning route of the beam, and radiation is executed by a plurality of the light beam scanning units to the respective plurality of divided regions to improve molding efficiency.
