A cupsole for footwear, said cupsole comprising at least a sidewall, a bottom surface and a central portion and wherein said sidewall circumscribes the central portion, said central portion having openings, preferably in the form of at least one honeycomb structure and wherein at least the sidewall and the bottom surface of the cupsole have a solid structure with no openings and wherein the complete cupsole is customized on the base of specific and measured data obtained directly from the user and printed in 1 single 3D printing step thereby using a thermoplastic polymer.

A fiber bound engineered material is provided that imparts an intended characteristic at an intended relative location. A fiber layer is entangled with additional fibers in a manner to create a non-uniform engineered material. The lack of uniformity of a fiber bound engineered material may be accomplished through manipulation of the fibers and/or through fiber binding a scrim. The fiber layer binds with additional fibers through entanglement such that a mechanical connection between the entangled fibers is provided. This entanglement allows the fibers to bind without supplemental adhesives, interlacing, or connections. Variations in the fibers and/or inclusion of scrim materials prior to entanglement allows for an intended characteristic (e.g., a functional characteristic) at an intended relative location (e.g., a position determined by an article to be formed therefrom).

Polymeric based closed cell foams, such as shape memory polymer foams, contain bubbles. Making these bubbles continuous is called reticulation. Disclosed are embodiments of a device and method to controllably reticulate polymer-based closed cell foams by puncturing the membranes of these polymer-based closed cell foams.

A vacuum insulated appliance includes a cabinet with an outer wrapper and an inner liner coupled to the outer wrapper to define an insulation cavity. The cabinet defines a passthrough opening through the outer wrapper and the inner liner. A passthrough cover is coupled to the cabinet over the passthrough opening. The passthrough cover has a bottom wall defining at least one service hole. A passthrough cavity is defined between the cabinet and the passthrough cover. At least one foam injection port is defined by the passthrough cover, and an expanding foam is disposed within the passthrough cavity. The expanding foam is configured to be inserted through the at least one foam injection port to at least partially fill the passthrough cavity.

An underride protection device for a battery-electric vehicle, having a sandwich arrangement with a core layer arranged between an upper cover layer and a lower cover layer made of a fiber-reinforced plastic material. In order to functionally improve the underride protection device, ribs are arranged on the upper cover layer, which are materially connected to the upper cover layer, wherein the ribs arranged on the upper cover layer are surrounded by a respective top layer, which is materially connected to the upper cover layer at two retaining sections.

A three-dimensional (3D) object production system and methods for 3D printing reactive components to form a thermoset product. The disclosure relates to Use of a 3D printer having a controller comprising one or more processors to print a 3D object. The disclosure also provides a 3D object production system and methods for 3D printing comprising adjusting one or more parameters of an at least one actuator to produce a 3D object based on a reaction rate between reactive components.

A thermosetting composition for injection molding comprising: (A) a compound represented by the following formula (A2) or (A3), and (B) a thermal polymerization initiator; wherein the composition further comprises no (G) titanium oxide or comprises (G) titanium oxide, when the composition comprises the component (G), the content of the component (G) is 5 parts by mass or less, based on a total of 100 parts by mass of components other than the component (B) and the component (C); and the composition comprises no polybutadiene di(meth)acrylate: ##STR00001##

A method for generating a three-dimensional printing composite hollow structure based on alternating connections of spatial curves is provided, relating to the field of 3D printing technologies. In the method, a target 3D model is discretized into layers, and sections are extracted layer-by-layer. The sections are classified based on topological states of the respective sections. For a non-holed section, it can be divided into two parts as a contour 1 and a contour 2. For a single-holed section, it can be extracted as the contour 1 and the contour 2. A surface 1 for all the contours 1 is generated, and a surface 2 for all the contours 2 is generated. Spatial curves f.sub.i and g.sub.i are intersected with the contour 1 and the contour 2 at P.sub.n,i and Q.sub.n,i respectively. Differentiated textures are generated from a combination of K-lines and L-lines.

A method for manufacturing a window for a polishing pad is disclosed. The method includes: a) mixing a curing agent with a polyurethane prepolymer having a temperature of 50 C. or higher to less than 100 C. to prepare a mixture; b) injecting the mixture into a mold heated to a temperature of 30 C. or higher to less than 100 C. to a thickness of 5 mm or less; c) demolding a polyurethane cured product from the mold; and d) processing the polyurethane cured product to a thickness of the window of the polishing pad. A polishing pad including the window is also disclosed.

Polyurethane thermal insulating foam is made in the presence of a small amount of cis- and/or trans-1,1,1,4,4,4-hexafluorobut-2-ene and a hydrocarbon blowing agent. Very low lambda values are obtained.
