At least a three-dimensional printer configured to model a modeled object and a terminal configured to issue a request for modeling of a modeled object are connected in a management system. The management system includes a free space detection unit and a transmission unit. The free space detection unit is configured to detect a free space in a three-dimensional printer chamber, based on a reservation for modeling of a modeled object. The transmission unit is configured to transmit, to the terminal, an offer for modeling of a modeled object capable of being modeled in the free space in the three-dimensional printer chamber.

A method of additive manufacture involves building a container 8 and a structure by fusing powder 12, 13, 14, such that the container contains the structure and unfused powder. The container 8 may be used in a method for predicting powder degradation in an additive manufacturing process. Containers containing different types of structure may be built to measure the effect of building different types of structures on powder degradation. A structure to be built may be characterised by classes of structural features it contains and information obtained used from building containers used to predict how building the structure will degrade powder.
