Three-dimensional fabrication method and three-dimensional fabrication apparatus

摘要

The present invention is a three-dimensional fabrication method for building up fabrication starting materials (100) into a prescribed three-dimensional shape by changing the form of (heating and melting) the fabrication starting materials and is characterized in comprising: a conveyance step in which a conveyor means (conveyor section (10)) conveys multiple fabrication starting materials (multiple fabrication starting materials (100) of different colors) toward respective form-changing means (heating and melting sections (31)); a form-changing step in which the form-changing means change the forms of the respective fabrication starting materials; a fabrication material-forming step in which a fabrication material-forming means (fabrication material-forming section (30)) forms a fabrication material by arranging the respective changed-form fabrication starting materials helically while twisting same; and a fabrication step in which a fabrication means (fabrication section (70)) forms a three-dimensional molding (102) by successively building up the fabrication material.
