Provided are a clear aligner set and an orthodontic treatment method considering resilience of a human body. The clear aligner set may include at least one first clear aligner, having a first restoring force to apply a first pressing force to teeth during a first period, and primarily wearable by an orthodontic patient, at least one second clear aligner, having a second restoring force greater than the first restoring force to apply a second pressing force greater than the first pressing force to the teeth during a second period, and secondarily wearable by the orthodontic patient, and at least one third clear aligner, having a third restoring force greater than the second restoring force to apply a third pressing force greater than the second pressing force to the teeth during a third period, and tertiarily wearable by the orthodontic patient.

A layered panel in which strength of a hinge can be improved regardless of the kinds of substrates configuring a front wall and a rear wall of the layered panel is provided. A layered panel in accordance with the present invention is a layered panel rotatable about a hinge as a rotary axis, characterized by including a front wall, a rear wall, and an intermediate layer interposed between the front wall and the rear wall, the hinge including the intermediate layer.

The invention relates to a process for preforming a composite material (I) in the form of a plate comprising reinforcing fibers bonded together, in particular by a plastic polymer material. In particular, such a process comprises an intermediate forming phase (b) comprising at least the following operations: introducing gas (III) into the second chamber (4), while maintaining the pressure P2 of the second chamber (4) below the external pressure Pext, and in particular atmospheric pressure, when the external pressure Pext is equal to atmospheric pressure, and thereby locally maintaining the upper diaphragm (2) at a distance from the lower diaphragm (1), and while maintaining, at the contact zone (5), both the alignment and the contact between the composite material (I) and the two diaphragms (1 and 2), evacuating gas (III) contained in the first chamber (3), so as to press the lower diaphragm (1) over the entire forming surface (22) present at the bottom (21) of the mold (20).

The invention also relates to a device adapted to the implementation of such a process.

The present disclosure provides a negative mold for luggage molding and an application thereof. The negative mold includes an upper mold holder (11), a convex mold (12), a lower mold holder (21), a concave mold (22), a lifting platform (23), and a material frame (31). The upper mold holder is arranged with a first airflow channel (111); in the adsorbed state, the upper mold holder abuts against the material frame to define an upper air cavity (112); air is blown downward through the first airflow channel to stretch the sheet (41), while each of the convex mold and the concave mold moves in a direction close to the sheet to define a molding space; in the mold detaching state, each of the convex mold and the concave mold moves toward in another direction away from the material frame to detach the molded sheet.

A method including inserting into a mold a first tool having a first surface. The method further includes printing a second tool from a polymer material and inserting the second tool into the first tool. The second tool having a smaller wall thickness than the first tool and including a second surface opposing and in contact with the first surface of the first tool and a third surface formed on an opposite side of the second tool than the second surface.
