Patent ID: 8616872

Claim:
A three-dimensional modeling apparatus, comprising: a supply mechanism configured to supply a powder material; a modeling box defining at least in part a deposition area in which the powder material supplied by the supply mechanism is deposited, the modeling box having a vertically-extending first side, a vertically-extending second side facially opposing the first side and a modeling stage extending horizontally and between the first side and the second side; a variable mechanism configured to vary a volume of the deposition area per a predetermined layer thickness so that the powder material is deposited per the predetermined layer thickness in the deposition area; a discharge mechanism configured to discharge liquid for forming a three-dimensional object to the powder material deposited per the predetermined layer thickness in the deposition area, the liquid being capable of hardening the powder material; and a control means for causing the discharge mechanism to discharge the liquid to the powder material, to thereby form a main body being an object being a target to be modeled and a frame body being an object formed to surround the main body of the three-dimensional object, the frame body commencing on and being in contact with the modeling stage and having a vertically-extending first frame body part disposed adjacent to the first side at a first distance and a vertically-extending second frame body part positioned opposite the first frame body part and disposed apart from the second side at a second distance being larger than the first distance.
