The invention provides a method for the production of a 3D printed object (100), wherein the method comprises (i) a 3D printing stage, the 3D printing stage comprising 3D printing a 3D printable material (110) to provide the 3D printed object (100) of printed material (120), wherein the 3D printing stage further comprises forming during 3D printing a channel (200) in the 3D printed object (100) under construction, wherein the method further comprises (ii) a filling stage comprising filling the channel (200) with a curable material (140) and curing the curable material (140) to provide the channel (200) with cured material (150), wherein the cured material (150) has a lower stiffness than the surrounding printed material (120).

A corrugated sheet metal wall sheathing for resisting external excitations such as wind or earthquake of light-framed wall structures. The sheathing has sheet profile proportioned to insure the top flutes deform laterally and yield at the end of the flute before the onset of any failure mode. A transverse slot in included in each top flute and adjacent web of the sheathing and spaced at intervals along the length of the sheathing.

A method for manufacturing an electronic device casing having a coupling structure is provided. The electronic device casing is made of a casing material including a supportive substrate and a first thermoplastic substrate. A preliminary connecting section is formed on the first thermoplastic substrate by a hot-pressing molding process, and a molding plastic material is injected onto the preliminary connecting section by an in-mold injection process. After being cooled, the molding plastic material engages with the preliminary connecting section to form a secondary connecting section for a coupling element to couple with. Thus, the coupling structure of the electronic device casing can be directly formed during a manufacturing process without any additional procedures, thereby overall manufacturing time and costs are reduced.

A mounting system includes a first and second mounting part having a first and second base part with a first and second plurality of first and second locking means respectively, for mounting two components to each other. Each of the locking means is attached to the respective base part and is provided with an attachment part extending from the base part, and a distal part provided as a head portion with at least one engaging section protruding sidewards over the attachment part. The locking means are laterally displaceable in relation to the base part to allow sidewards displacement of the engaging sections for engagement and disengagement of the locking means and thus the first and the second base. In the engaged state, latching means are provided blocking the sidewards displacement of the engaging sections to an extent that a disengagement of the locking means is prevented.

A component (34A, 34B, 34C) has a core formed of a stack (25, 36) of sheets (20) of material with cutouts (22A) aligned to form passages (38) in the core. An outer casing (29) spans the stack axially (51), brackets at least parts of opposed ends of the stack, and holds the sheets together in axial compression (46). Respective cooperating elements (30, 31) on the casing and the stack may register the casing with respect to the stack. Pins (24) in some sheets may engage holes (23) in adjacent sheets to register the sheets with each other. The casing may be segmented (28A, 28B, 28C). A hoop (66) may be compressed around the segmented casing. A gas turbine fuel injector may be formed of a stack (36) with an inlet element (44) compressed (46) onto the stack by the casing (29).

The invention comprises a relatively lightweight cementitious-based material panel. The cementitious-based material panel comprises a foam insulating panel having a first surface and a second surface; a first structural layer of cementitious-based material formed on the first surface of the foam insulating panel and affixed thereto; and a second non-structural layer of cementitious-based material formed on the second surface of the foam insulating panel and affixed thereto. The second non-structural layer of cementitious-based material is substantially thinner than the first structural layer of concrete. The second non-structural layer of cementitious-based material is preferably formed from polymer modified concrete, plaster or mortar. A method of making the cementitious-based material panel is also disclosed.

A method for producing a reinforced concrete part, having a tensioned portion subjected to pull stresses and tending to stretch under the load, and which includes a reinforcing frame with at least one tensioned longitudinal bar rigidly connected to the concrete by an adhesive connection that determines a tangential adhesive stress along the bar that varies on the basis of applied pull stresses. Each tensioned longitudinal bar has, on at least one portion of the length thereof, a discontinuous series of spaced blocking areas that each include a plurality of elements for anchoring into the concrete and which are separated from each other by a series of sliding areas, in each of which an increase in the adhesion stress above a limit value causes the bar to disengage, without disrupting the concrete, on at least a portion of the length between the two blocking areas with an extension of the bar corresponding to applied pull stresses, the extension being distributed over the entire length of the disengaged portion of the bar.

The present invention provides a laminate material having a polyester film and a web of polyester fibers cohesively bonded directly thereto, such that portions of the fibers are bonded to the polyester film and portions of the fibers are free from the polyester film. The invention may also include a glass reinforced polymer layer formed on the laminated facer where the polymer of the glass reinforced polymer layer is commingled with the nonwoven of the laminated facer. The laminate may further include a second polymer layer having a thickness joined to the fiber layer and/or a layer of hot melt adhesive applied to the polyester fibers. Also presented is a composite material having a polyester film, a layer of polyester fibers bonded to the second polymer layer; a second polymer layer joined to the polyester film; and a glass reinforced polymer layer formed on the laminated facer, where the polymer of the class reinforced polymer layer is commingled with the nonwoven of the laminated facer.

A cross-laminated timber panel comprises a plurality of layers of lumber boards, each layer comprising a number of the lumber boards laid side-to-side pointing to a direction, each layer being disposed perpendicular to the direction of an adjoining layer; and an insert member replacing one of the lumber boards, the insert member having a different material or configuration than the lumber boards.
