Abstract:
A formation sheet is equipped with (i) a base, and (ii) n thermal expansion layers (n is greater than or equal to two) stacked on a first main surface of the base and each including a binder and a thermal expansion material that expands due to heat. Among post-expansion average particle sizes of the thermal expansion materials included in the n thermal expansion layers, a post-expansion average particle size of the thermal expansion material included in an n-th thermal expansion layer is smallest.
Abstract:
An thermally expandable sheet includes a base and a thermal expansion layer arranged on one surface of the base and configured to be used in manufacture of a shaped object by swelling of at least a portion of the thermal expansion layer. The thermal expansion layer includes a first thermally expandable material having a first expansion initiation temperature and a first maximum expansion temperature, and a second thermally expandable material having a second expansion initiation temperature and a second maximum expansion temperature. The first expansion initiation temperature and the second expansion initiation temperature are high in comparison to a temperature of an environment in which the shaped object is to be placed. The second maximum expansion temperature is high in comparison to the first maximum expansion temperature.
Abstract:
A thermally expandable sheet includes: a thermally expansive layer formed on a one surface of a base; a first ink receiving layer that is provided on the thermally expansive layer for receiving ink; a film provided on the first ink receiving layer; and a second ink receiving layer that is provided on the film for receiving ink; wherein the first ink receiving layer is formed of a material that provides a texture a different from a texture of the second ink receiving layer.
Abstract:
A formable resin sheet includes a base and a thermally expansive layer that contains a thermally expandable material and is formed on one surface of the base. When the thermally expansive layer is expanded, the base is deformed with expansion of the thermally expansive layer, such that the base is deformed in an embossed shape, and a deformation amount of the base is greater than an expansion height of the thermally expansive layer.
Abstract:
An ink is used for forming a photothermal conversion layer used for causing expansion of at least a portion of a thermal expansion layer of a thermally-expandable sheet. The ink includes an inorganic infrared absorbing agent having a higher absorptivity in at least one region of an infrared light spectrum than in a visible light spectrum. A base of the ink is white.
Abstract:
A thermally expandable sheet in which a thermally expansive layer that contains a thermally expandable material is formed on one side of a base, and wherethe thermally expansive layer is distended, the base deforms following distension of the thermally expansive layer and the base deforms into an embossed shape.
Abstract:
A printing method includes the steps of: printing a predetermined pattern on a distendable sheet before distending; distending the distendable sheet printed the predetermined pattern; calculating a displacement amount of the predetermined pattern between before and after the distending of the distendable sheet; deforming an original image by a deformation amount determined based on the calculated displacement amount; and printing the deformed original image as an image for printing on the distendable sheet.
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.
Abstract:
A thermally expandable sheet including two or more thermally expandable layers that are laminated, the thermally expandable layers each expanding upon being heated to or above a predetermined expansion start temperature, wherein the thermally expandable layers include two adjacent layers different from each other in the expansion start temperature.
Abstract:
A thermally expandable sheet includes:a first thermally expansive layer that is formed on one side of a base and contains a first thermally expandable material; anda second thermally expansive layer that is formed on the first thermally expansive layer and contains a second thermally expandable material,wherein the second thermally expandable material further contains white pigment.
