Abstract: A three dimensional modeling method for fabricating a modeled object having a cavity therein is disclosed. The three dimensional modeling method includes modeling the modeled object with first powder, the modeled object including an opening connecting the cavity and an outside of the modeled object; filling the cavity with second powder from the opening; sintering the modeled object whose cavity has been filled with the second powder in the filling; and removing the second powder in the cavity from the opening.

Abstract: A fabricating apparatus is configured to fabricate a three-dimensional object, the apparatus includes a discharging device, a heating device, and control circuitry. The discharging device is configured to discharge a fabrication material to form a fabrication material layer. The heating device is configured to heat the fabrication material layer formed by the discharging device. The control circuitry is configured to control at least one of a heating range of the fabrication material layer heated by the heating device and a heating energy applied to the fabrication material layer by the heating device when the discharging device discharges the fabrication material to laminate another fabrication material layer on the fabrication material layer heated by the heating device.

Abstract: The inventive heat-shrinkable polystyrene film is high in shrinkability in the longitudinal direction that is its main shrinkage direction, is excellent in perforated line openability, and has high toughness. The heat-shrinkable polystyrene film is characterized by particular values with respect to hot-water heat shrinkage ratio in the longitudinal and width directions, right angle tear strength in the width direction, and breaking energies in the longitudinal and width directions.
