Shaping device and shaped object manufacturing method
A shaping device includes a cutting unit configured to cut a first shaped product or an intermediate component formed by adding a shaping material to the first shaped product on a stage, and a control unit configured to control the cutting unit to cut the first shaped product or the intermediate component to shape a shaped object different from the first shaped product and the intermediate component.
1. A shaped object manufacturing method comprising:
depositing a first shaping material on a stage to form a first shaped product via a first head provided at a shaping device, the first shaped product being a first molding die for an injection molding device;
using the first shaped product in the injection molding device as the first molding die to form a molded object;
placing the first shaped product, which has been used in the injection molding device as the first molding die, on the stage;
further depositing a second shaping material on the first shaped product, which has been used in the injection molding device as the first molding die, to form a second shaped product on the first shaped product via the first head, the second shaped product being a projection;
cutting part of the first shaped product with the projection to form a third shaped product via a second head provided at the shaping device next to the first head, the third shaped product being a second molding die; and
using the third shaped product in the injection molding device as the second molding die to form a subsequent molded object.
2. The shaped object manufacturing method according to claim 1 ,
wherein the first shaped product contains a thermoplastic resin.
3. The shaped object manufacturing method according to claim 1 ,
wherein the first head includes a plasticizing mechanism configured to plasticize at least a part of a source material to generate the first shaping material, and the plasticizing mechanism includes a rotor and a barrel facing the rotor,
the source material is supplied into a gap between the rotor and the barrel to form the first shaping material by rotating the rotor relative to the barrel, and
a cut material in the cutting of the part of the first shaped product is a reusable material to reuse as the source material.
4. The shaped object manufacturing method according to claim 3 ,
wherein the plasticizing mechanism includes the rotor having a groove forming surface in which a groove is formed, the barrel having a facing surface facing the groove forming surface and a communication hole formed in the facing surface, and a heater configured to heat the source material supplied into the gap between the rotor and the barrel.
5. The shaped object manufacturing method according to claim 3 , further comprising:
further depositing the second shaping material including the reusable material to form another product on the first shaped product after the cutting of the part of the first shaped product; and
cutting another part of the first shaped product with the projection and the another product to form the third shaped product,
wherein the plasticizing mechanism is configured to plasticize at least a part of the reusable material, and
the another part includes the plasticized reusable material.
6. The shaped object manufacturing method according to claim 5 , further comprising:
transporting the reusable material from the stage to the plasticizing mechanism.
7. The shaped object manufacturing method according to claim 5 , further comprising:
selecting a specific reusable material from the reusable material based on a size of the reusable material.
8. The shaped object manufacturing method according to claim 3 , further comprising:
transporting the reusable material from the stage to the plasticizing mechanism; and
selecting a specific reusable material from the reusable material based on a size of the reusable material.
