Title:
THREE-DIMENSIONAL OBJECT FORMING APPARATUS, THREE-DIMENSIONAL OBJECT FORMING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/189654
Kind Code:
A1
Abstract:
[Technical Problem]　An object is to improve object forming quality upon performing material-discharging object forming process. [Solution to Problem]　A three-dimensional object forming apparatus includes a plurality of discharging units configured to discharge a modelling material and a supporting material, respectively; a forming stage on which a three-dimensional object is formed; one or more flattening units configured to flatten a surface of each of the discharged modelling material and supporting material; one or more curing units configured to cure each of the discharged modelling material and supporting material; and at least one controlling unit configured to control an object forming operation. The at least one controlling unit is configured to relatively move the forming stage and the plurality of discharging units, perform a modelling material layer forming operation of causing a corresponding discharging unit of the plurality of discharging units to discharge the modelling material at each of forward and return strokes, and causing the one or more flattening units and the one or more curing units to flatten and cure the modelling material immediately after the discharging of the modelling material at the return stroke, and perform a supporting material layer forming operation of causing a corresponding discharging unit of the plurality of discharging units to discharge the supporting material at each of forward and return strokes, and causing the one or more flattening units and the one or more curing units to flatten and cure the supporting material immediately after the discharging of the supporting material at the return stroke.
