Abstract

A structure in which complexity of the moving path of the nozzle during forming is suppressed even if the structure has regions with different elasticity and a manufacturing method for a structure that can suppress complexity of the moving path of the nozzle when forming the structure with regions with different elasticity. The structure includes a formed body with a linear structure formed of a linear resin. The formed body includes first and second elastic regions, and the linear resin forming the first elastic region is thinner than the linear resin forming the second elastic region.

First claim

The invention claimed is:

1. A structure comprising:
a base layer; and
a covering layer formed at a forming temperature of 238 degrees Celsius, which is a formed body, covering an entire area of an upper surface of the base layer, wherein the covering layer includes a linear structure, the linear structure is formed of a linear portion, and the base layer is made of a shape memory material containing a shape memory polymer, the covering layer is made of an elastomer, the elastomer is softer than the shape memory material at 25 degrees Celsius,
a glass-transition temperature Tg of the shape memory polymer is 35 to 100 degrees Celsius,
a ratio of an elastic modulus of the shape memory polymer at Tg+20 degrees Celsius to an elastic modulus of the shape memory polymer at Tg-20 degrees Celsius is equal to or larger than 10,
the base layer and the covering layer are formed by laminating the linear structure which is formed of a linear resin by two-dimensionally moving a nozzle configured to eject the linear resin, and
the linear structure includes a plurality of grooves extending parallel to one another.
