Abstract: Devices, systems, methods and computer program products are disclosed that facilitate part layer curing by an additive manufacturing device wherein each element of the part layer is exposed to light from a light source until the element receives sufficient energy to cure. In an aspect, received energy is calculated based on both the light received directly from the light source and light received from surrounding elements due to dispersion and other effects. The present disclosure enables consistent curing across a part layer, facilitate the creation of sharp outer structures, and allow fragile structures to be built alongside larger structures without a loss of quality, clarity, or resolution.

Abstract: A tubular lower mold partitioning wall is erected on a lower mold, and a three-dimensional mesh-like body is disposed with a part of a side face exposed with respect to the lower mold partitioning wall. When a pad main body is molded by foaming a liquid raw material, the mesh-like body is penetrated through the pad main body in a thickness direction. Since the mesh-like body is disposed with a part of the side face exposed with respect to the lower mold partitioning wall, the liquid raw material is hardened between the fibers on the side face of the mesh-like body, and the side face is attached to the pad main body. Therefore, it is possible that the mesh-like body is not easily displaced with respect to the pad main body while suppressing a sweaty feeling.

In particular embodiments, the material-engaging portion is a cavity. In other embodiments, the material-engaging portion is associated with one or more longitudinal members extending across a portion of the first mold member.

Abstract: A three-dimensional mesh-like body is disposed on a molding face of a lower mold onto which a liquid raw material of flexible foam is poured. An upper mold is laid over the lower mold to form a cavity, a projection projected on the upper mold toward the cavity is contacted with the three-dimensional mesh-like body, and the three-dimensional mesh-like body is fixed. The three-dimensional mesh-like body is attached and fixed to a front surface of a pad main body, so that the three-dimensional mesh-like body can be prevented from being displaced with respect to the pad main body. Moreover, the position of the three-dimensional mesh-like body can be prevented from being displaced in the process of foaming the liquid raw material because of the projection, and a vent hole can be formed on the pad main body. As a result, a sweaty feeling can be suppressed.
