Abstract: An additive manufacturing device is provided with a beam irradiation unit irradiating a conductive powder disposed in a layered shape with a beam, a nondestructive inspection unit detecting a flaw in a surface layer of an additively manufactured article formed of the hardened conductive powder, and an energy control unit controlling energy of the beam. The energy control unit increases energy of a beam when a repairing region set in accordance with results of flaw detection by the nondestructive inspection unit is irradiated with the beam.
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: Systems and methods are provided for fabricating composite parts. One embodiment is a method of forming a composite part. The method includes laying up opposing composite facesheets, placing a viscous material between the facesheets, increasing a distance between the facesheets, and solidifying the facesheets and the viscous material into an integral composite part.
Abstract: A manufacturing process of EPC composite structure floors which includes an LVT layer and a substrate layer from top to bottom includes steps of separately and independently preparing the LVT layer and the substrate layer, and performing stacking and attaching the LVT layer and the substrate layer with glue so as to obtain finished products of the EPC floors. The substrate layer needs to be subjected to a working procedure of tempering before being stacked and attached with the LVT layer. The EPC floors manufactured by the process completely meet ISO standard requirements, and when being maintained in an environment of 80° C. for 6 hours, the WPC floors can also maintain a size change rate of 0.15% or below.

Abstract: A vehicle interior board which is thin, lightweight, has high strength, has less degradation, peeling and the like near an end portion of a metal plate, and has high quality and excellent productivity; and a method for manufacturing the same. The vehicle interior board includes a pair of metal plates and a foamed polyurethane layer formed between the pair of metal plates. A projecting ridge projecting outwardly and extending in a predetermined direction along the outer surface is formed on an outer surface of the metal plate. Thus, it is possible to obtain desired strength and rigidity even when the metal plates or the foamed polyurethane layer are thinned or when a lightweight aluminum plate or the like is adopted as the metal plates. Therefore, it is possible to reduce weight of a vehicle interior board.
Abstract: A system and methods for manufacturing and constructing a fence panel or pickets using engineered wood products, including, but not limited to, oriented-strand board (OSB), fiber strand, or laminated strand lumber. An entire piece of durable, treated engineered wood panel is divided into multiple “fence blanks” of equal size. Each fence blank is then subjected to edge profiling on top and bottom edges, and top feature milling to create fence top features, with finishing, texture, printing, paper overlay, or combinations thereof, added to one or both faces of the blank. Blanks may be milled in a stack. Blanks may then have grooves or other finishing features added to create a finished fence panel. Alternatively, a fence blank can be slit or cut into multiple raw pickets, also with finishing treatments to one or both faces, to create a series of raw pickets. The resulting finished fence panel or pickets provide the authentic look and appeal of real wood, but with the advantages of treated engineered wood.

Abstract: Methods of rapidly debonding encapsulant in solar modules and disassembling the modules for reuse or recycling of components. Electromagnetic radiation is applied to a solar module in a temperature and humidity-controlled environment to debond the encapsulant layers. Peel blocks are used to separate the front layer and back sheet of the module from the solar cells. The components are then sorted for reuse or recycling of valuable materials. The embodiments described also include a system of performing the methods that can be arranged in one or more shipping containers to be delivered to a solar module decommissioning site.
