Abstract
A three-dimensional modeling apparatus for fabricating a three-dimensional object includes a plasticizing section that plasticizes a thermoplastic material to transform into a molten material; an ejection section for ejecting the molten material; a first air blowing section that blows air from a circumference of the nozzle toward the molten material ejected from the nozzle; a platform on which the molten material ejected from the nozzle is deposited; and a control unit that changes a relative positional relationship between the ejection section and the platform.
