An insert including a taper is covered with a molten metal. A metal molded product with the insert joined thereto is generated by semi-cooling the molten metal to a press-fitting temperature which is higher than a recrystallization temperature of the molten metal and lower than a melting point of the molten metal. A fitting hole which is filled with the insert is formed in the metal molded product. The taper is fitted into the fitting hole. An undercut is not formed in front of a tip of the taper. The insert is press-fitted into the fitting hole while pressing and extending the fitting hole with the taper in a thinning direction of the taper at a press-fitting temperature. The metal molded product is further cooled with the press-fitting maintained.

Various components of an electronic device housing and methods for their assembly are disclosed. The housing can be formed by assembling and connecting two or more different sections together. The sections of the housing may be coupled together using one or more coupling members. The coupling members may be formed using a two-shot molding process in which the first shot forms a structural portion of the coupling members, and the second shot forms cosmetic portions of the coupling members.

In the context of additive manufacturing processes wherein an object is built by layered accumulations of discrete instantaneous deposits of feedstock material at specific locations according to a three-dimensional digital data model, systems and methods are taught for operating multiple independently-moving depositing devices in a shared build space to build the object. In some embodiments, depositing components perform discrete material depositing actions according to sequential lists of deposit location instructions which are dynamically sortable, enabling a control methodology to alleviate collision risks among depositing components and to improve thermal conditions of a workpiece during construction. Further embodiments provide for dynamic apportionment of discrete deposition actions among the available depositing devices for load balancing and fault tolerance.

A 3D printer successively fuses sheet material in a stack to form a three-dimensional object. The sheet material may provide a mesh separating islands of material that will be fused to produce the desired three-dimensional object. The mesh provides support for the island material during the fusing process and may be removed afterwards.

Disclosed are a rolled (FeCoNiCrR.sub.n/Al)-2024Al composite panel and a preparation method therefor. The preparation method involves taking pure aluminum as a matrix, adding an FeCoNiCrR.sub.n medium-entropy alloy with a high strength and toughness as an reinforcing phase to prepare an FeCoNiCrR.sub.n/Al composite material, then laminating the FeCoNiCrR.sub.n/Al composite material with aluminum alloy 2024, and preparing the (FeCoNiCrR.sub.n/Al)-2024Al composite board by means of hot-rolling recombination, which solves the problem that high-strength aluminum matrix composites (AMCs) are prone to instantaneous breakability and low ductility, thereby improving the overall performance of the material. The present disclosure adopts microwave sintering (MWS) to fabricate a medium-entropy alloy-reinforced AMC, and adopts hot-roll bonding to fabricate the (FeCoNiCrR.sub.n/Al)-2024Al metal composite panel. The composite panel fabricated by the present disclosure has excellent comprehensive mechanical properties, and has high application values for promoting the application of modern lightweight and high-efficiency industrial materials in aerospace, new energy vehicles, and the like.

A method includes forming one or more plug holes into a tool surface of a body. The one or more plug holes are partially formed around a landing surface portion of a plug in the body. The method also includes engaging a tool with the landing surface portion of the plug in the body, and using the tool to cut away the plug from the body and at least part of the body to form a tooled void into the body.
