Patent ID: 11065838

Abstract:
A shaped object includes a thermally expandable sheet including (i) a base, (ii) a thermal expansion layer disposed on a first surface of the base and including a thermally expandable material, and (iii) a thermal conversion member disposed on at least one of a second surface of the base or the thermal expansion layer, and including a thermal conversion material for conversion of electromagnetic waves into heat. The thermal conversion member further includes thermal conversion layers disposed on an entire region corresponding to an expansion region for expansion of the thermal expansion layer. At least part of one of the thermal conversion layers is disposed at a location separated from an adjacent other thermal conversion layer. Upon expansion of the thermal expansion layer, (i) the thermal expansion layer partially peels away from the thermal expansion layer in a region where the thermal conversion layer is disposed, and (ii) the thermal expansion layer also expands in a region between the one thermal conversion layer and the other thermal conversion layer.
