Abstract
In a three-dimensional object formed by bending and deforming a sheet-like base material made of a thermoplastic resin at a ridge line, a surface of the base material bent and oriented outward at least at the ridge line is covered with a thermal expansion layer that expands when heated to a thermal deformation temperature of the thermoplastic resin or a higher temperature, and the thermal expansion layer is expanded at the ridge line.

A three-dimensional object formed by bending and deforming a sheet-like base material made of a thermoplastic resin at a ridge line, wherein
- a surface of the base material bent and oriented outward at least at the ridge line is covered with a thermal expansion layer that expands when heated to a thermal deformation temperature of the thermoplastic resin or a higher temperature, and
- the thermal expansion layer is expanded at the ridge line.
A three-dimensional object manufacturing method comprising:
- a thermal expansion layer formation step of forming a thermal expansion layer to expand when heated to a predetermined temperature range on a sheet-like base material made of a thermoplastic resin of which a thermal deformation temperature is equal to or lower than the predetermined temperature range;
- a printing step of drawing a line on at least one surface of a thermal expansion sheet on which the thermal expansion layer is formed in the thermal expansion layer formation step by a printing material that contains a photothermal conversion component to convert absorbed light into heat and emit the heat;
- and
- a light irradiation step of irradiating the surface on which the line is drawn with light to be converted into heat by the photothermal conversion component, wherein
- in the light irradiation step, the thermal expansion layer immediately below the line is expanded and the base material is bent at the line such that the expanded thermal expansion layer is oriented outward.
A three-dimensional object manufacturing method comprising:
- a printing step of drawing a line by a printing material that contains a photothermal conversion component to convert absorbed light into heat and emit the heat;
- a thermal expansion layer formation step of forming a thermal expansion layer to expand when heated to a predetermined temperature range on one surface of a sheet-like base material that is made of a thermoplastic resin of which a thermal deformation temperature is equal to or lower than the predetermined temperature range and transmits the light;
- and
- a light irradiation step of irradiating the base material with light to be converted into heat by the photothermal conversion component, wherein
- in the printing step, the line is drawn on the one surface of the base material or the base material side of the thermal expansion layer, and
- in the light irradiation step, the thermal expansion layer immediately below the line is expanded and the base material is bent at the line such that the one surface is oriented outward.
