Abstract
A three-dimensionally shaped object forming sheet includes: a thermally expansive layer distending at a predetermined temperature or higher; a base laminated on one side thereof with the thermally expansive layer; and a photothermal conversion layer for converting absorbed light to heat, formed on at least one side, wherein the base includes a first base and a second base that are laminated; and the first base has an elasticity that is greater than an elasticity of the second base.
Claims7
A production method for a three-dimensionally shaped object, comprising:
- a step of producing a sheet by providing a thermally expansive layer on a main surface of a base on a side of a first base, the base including the first base and a second base that are laminated thereon;
- a step of providing an electromagnetic wave heat conversion layer on a main surface of the base of the sheet on a side of the second base;
- and
- an unevenness forming step of forming unevennesses on a surface of the sheet by causing the thermally expansive layer of a region corresponding to the electromagnetic wave heat conversion layer to distend by irradiating the electromagnetic wave heat conversion layer with electromagnetic waves of a predetermined wavelength,
- wherein the first base and the second base have elasticities different from each other.
A production method for a three-dimensionally shaped object having unevennesses in a surface, the production method comprising sequentially performing:
- a base laminating step of producing a base by laminating together a second base and a first base having a greater elasticity than an elasticity of the second base;
- a thermally expansive layer forming step of forming, on a main surface of the base on a side of the first base, a thermally expansive layer that distends at a predetermined temperature or higher;
- a photothermal conversion layer printing step of printing a photothermal conversion layer for converting absorbed light to heat and releasing the heat on a main surface of the base on a side of the second base;
- and
- a light irradiation step of irradiating light so as to reach the photothermal conversion layer thereby causing the thermally expansive layer in a region where the photothermal conversion layer is formed to distend.
A production method for a decorated three-dimensional object having unevennesses in at least a portion of a surface, the production method comprising sequentially performing:
- a base laminating step for producing a base by laminating a second base and a first base having a greater elasticity than an elasticity of the second base;
- a thermally expansive layer forming step of forming, on a main surface of the base on a side of the first base, a thermally expansive layer that distends at a predetermined temperature or higher;
- a photothermal conversion layer printing step of printing a photothermal conversion layer for converting absorbed light to heat and releasing the heat on a main surface of the base on a side of the second base;
- a light irradiation step of irradiating light from the side of the second base of the base so as to reach the photothermal conversion layer thereby causing the thermally expansive layer in a region where the photothermal conversion layer is formed to distend;
- and
- an affixing step of affixing the base to a surface of an article.
