Abstract
Disclosed is a method for manufacturing a resin product using a fused deposition modeling-type 3D printer, wherein a first molded body is produced using a first resin that has laser light absorption properties using the 3D printer. In addition, a second molded body is produced, using the 3D printer, so as to be laminated on the first molded body by supplying a second resin that has laser light transmissivity to the surface of the first molded body. Then, the first molded body and the second molded body are welded to each other by irradiating laser light along a path that extends from the second molded body side to the first molded body through an irradiation region between the first molded body and the second molded body.

A method for manufacturing a resin product using a fused deposition modeling-type three-dimensional printer that produces a molded body by supplying a molten resin in a string-like shape from a modeling nozzle, the method comprising:
- producing a first molded body using a first resin having laser light absorption properties;
- producing a second molded body by supplying a second resin having laser light transmissivity to a surface of the first molded body so as to be laminated on the first molded body;
- and
- welding the first molded body and the second molded body by irradiating laser light along a path that extends from the second molded body side to the first molded body through an irradiation region between the first molded body and the second molded body.
A manufacturing device for a resin product using a fused deposition modeling-type three-dimensional printer that produces a molded body by supplying a molten resin in a string-like shape from a modeling nozzle including a first modeling nozzle and a second modeling nozzle, wherein
- the three-dimensional printer includes
- a molding control unit that controls an operation of the first modeling nozzle, and produces a first molded body by supplying a first resin that has laser light absorption properties, and
- a lamination control unit that controls an operation of the second modeling nozzle, and produces a second molded body that is laminated on the first molded body by supplying a second resin that has laser light transmissivity to a surface of the first molded body,
- the manufacturing device includes
- a laser device that has a laser irradiation unit that irradiates laser light, and
- the laser device includes
- a laser control unit that controls an operation of the laser irradiation unit, and welds the first molded body and the second molded body to each other by irradiating the laser light along a path that extends from the second molded body side to the first molded body through an irradiation region between the first molded body and the second molded body.
A manufacturing device for a resin product using a fused deposition modeling-type three-dimensional printer that produces a molded body by supplying a molten resin in a string-like shape from a modeling nozzle including a first modeling nozzle and a second modeling nozzle, wherein
- as the three-dimensional printer, provided are
- a molding device having a molding control unit that controls an operation of the first modeling nozzle, and produces a first molded body by supplying a first resin that has laser light absorption properties, and
- a lamination device having a lamination control unit that controls an operation of the second modeling nozzle, and produces a second molded body that is laminated on the first molded body by supplying a second resin that has laser light transmissivity to a surface of the first molded body,
- the lamination device includes
- a laser device that has a laser irradiation unit that irradiates laser light, and
- the laser device includes
- a laser control unit that controls an operation of the laser irradiation unit, and welds the first molded body and the second molded body to each other by irradiating the laser light along a path that extends from the second molded body side to the first molded body through an irradiation region between the first molded body and the second molded body
