Three-dimensional modeling apparatus, three-dimensional model body manufacturing method, and three-dimensional modeling data

A three-dimensional modeling apparatus that performs three-dimensional modeling by repeatedly scanning a modeling material arranged on a modeling stage with an energy beam to form a solidified layer, comprising:

• a cover that includes an energy beam transmitting portion that allows the energy beam to pass, locally surrounds a portion of the modeling material arranged on the modeling stage irradiated with the energy beam, and suppresses diffusion of fumes generated by irradiation of the energy beam;
• and
• a stream regulating mechanism that regulates a stream of gas containing the fumes so as to cause the fumes to be apart upwardly from the portion of the modeling material irradiated with the energy beam in the cover toward an upper portion of the cover.

A three-dimensional modeling apparatus that performs three-dimensional modeling by repeatedly scanning a modeling material arranged on a modeling stage with an energy beam to form a solidified layer, comprising:

• a cover that includes an energy beam transmitting portion that allows the energy beam to pass, locally surrounds an irradiation position on the modeling material arranged on the modeling stage irradiated with the energy beam, and suppresses diffusion of fumes generated by irradiation of the energy beam;
• and
• a moving device that moves the cover so as to allow the energy beam to pass through the energy beam transmitting portion, according to scanning with the energy beam.
