Abstract
A three-dimensional shaping apparatus includes a melted material generator, a nozzle, a flow passage, a filter chamber, and a filter. The melted material generator generates a melted shaping material. The nozzle discharges the shaping material from the melted material generator. The shaping material is guided to the nozzle through the flow passage. The filter chamber is provided between the flow passage and the nozzle. The filter is disposed in the filter chamber and has pores through which the shaping material passes. A filter chamber cross-sectional area is larger than a flow passage cross-sectional area, and a filter cross-sectional area is larger than the flow passage cross-sectional area. The filter chamber cross-sectional area and filter cross-sectional area are perpendicular to a direction from the flow passage toward the nozzle, and the flow passage cross-sectional area is perpendicular to a flowing direction of the shaping material in the flow passage.
