Three-dimensional shaping method and shaped object complex as well as three-dimensional shaping apparatus

摘要

A three-dimensional shaping method includes forming a combination to be each level of a three-dimensional shaped object and also forming a combination to be each level of a shaped object support member in each of a plurality of powder material layers having an uncured powder material in accordance with hierarchical shape data corresponding to each of the powder material layers.

1. A three-dimensional shaping method for a three-dimensional shaping apparatus, comprising:
forming a plurality of combinations to respectively be a plurality of levels of a three-dimensional shaped object and also forming a plurality of combinations to respectively be a plurality of levels of a shaped object support member in a plurality of respective powder material layers each having an uncured powder material in accordance with hierarchical shape data corresponding to each of the powder material layers, the shaped object support member comprising a pillar which is formed around the three-dimensional shaped object and a tray body which is supported by the pillar and is formed to cover the three-dimensional shaped object; wherein said forming the plurality of combinations to be the plurality of levels of the three-dimensional shaped object and said forming the plurality of combinations to be the plurality of levels of the shaped object support member include:
stacking a powder material layer having an uncured powder material of a first upper level so as to cover the combinations of the three-dimensional shaped object and a lower part of the combinations of the pillar of the shaped object support member which are formed in the powder material layers of lower levels,forming an upper part of the combination of the pillar of the shaped object support member in the powder material layer of the first upper level so as to be bound to a part of the lower part of the combinations of the pillar,stacking a powder material layer having an uncured powder material of a second upper level so as to cover the combinations of the three-dimensional shaped object and the upper part of the combination of the pillar, andforming a combination of the tray body of the shaped object support member in the powder material layer of the second upper level so as to be bound to the upper part of the combination of the pillar, and so as to face the combinations of the three-dimensional shaped object through an uncured portion of the powder material layer of the first upper level.
