INJECTION- OR COMPRESSION-MOLDED ARTICLES

Various embodiments disclosed relate to injection-molded or compression-molded articles. A method of injection molding or compression molding an article includes directing a shot of molten material into a mold cavity including a plurality of contacting substantially identical modular mesh parts to fill the mold cavity. The method also includes solidifying the shot of molten material to form the article including the plurality of modular mesh parts and the solidified shot of molten material. Various embodiments also provide parts machined from a block produced by various methods of injection molding or compression molding.

3-D PRINTED PACKAGE CUSTOMIZATION
20210253280 · 2021-08-19 ·

Items may be packaged for shipping or storage using additive manufacturing techniques, also known as three dimensional (3-D) printing. Packages made by such processes may be referred to as 3-D printed packages. The 3-D printed packages may be customized based on one or more items contained in the package, a recipient of the package, a sender of the package, and/or a destination location of the package. The customizations may include two-dimensional and/or three-dimensional customizations on an interior and/or exterior of the 3-D printed packages.

Shaker flask stand with composite legs

A flask stand is configured to support a flask and includes a base ring and a plurality of legs. The base ring is configured to support a lower portion of the flask. Each leg is secured to the base ring and extends outward from the base ring. Each leg includes a body, a lattice, and an elastomeric foot. The body includes a first end portion that is secured to the base ring with the foot portion being opposite the first end portion. The lattice is formed within the foot portion and includes a plurality of members that form an open-mesh frame that defines a plurality of voids between adjacent members of the frame. The elastomeric foot is formed of an elastomer and is disposed about the lattice and within the voids of the lattice. The foot is configured to engage a surface to support the body relative to the surface.

Tridirectional laid scrims for reinforcement purposes

A triaxial laid scrim includes a first, second and third set of continuous fibers. The fibers of each set are regularly spaced apart and are parallel to each other. The fibers of the first set are parallel to the warp direction or to the weft direction of the scrim. The fibers of the second set and the third set are oriented symmetrically to each other, respectively at an angle of 30°-80° with respect to the fibers of the first set. Distances between the fibers of the second set and the fibers of the third set are identical. The fibers of the second set cross the fibers of the third set at the intersection thereof with the fibers of the first set, thereby defining regular openings having an isosceles triangle shape. The fibers are coated and attached to each other by a coating that does not fill-up the triangle-shaped openings.

Thermoplastic cellular network toughened composites

A composite article including fiber tows and a network including material drawn or pulled between the fiber tows. The network forms a physical barrier reducing propagation of cracks in the composite article. Exemplary structures described herein are the first to use a novel cellular architecture to toughen resin infused composites and create a continuous through thickness reinforcement that does not induce fiber breakage.

Metal objects spanning internal cavities in structures fabricated by additive manufacturing

A three-dimensional electronic, biological, chemical, thermal management, and/or electromechanical apparatus can be configured by depositing one or more layers of a three-dimensional structure on a substrate. Such a three-dimensional structure can include one or more internal cavities using an additive manufacturing system enhanced with a range of secondary embedding processes. The three-dimensional structure can be further configured with structural integrated metal objects spanning the internal cavities (possibly filled with air or even evacuated) of the three-dimensional structure for enhanced electromagnetic properties.

Composite foam

Composite materials having superior material properties useful as impact absorbing devices can be fabricated by embedding a lattice structure (e.g., polymer lattice structure) within a foam, so that the foam reinforces the lattice structure under impact. Materials and dimensions of the foam and the lattice structure may be selected to achieve composite materials having tailored impact absorbing elastic and/or viscoelastic responses over a wide range of temperatures.

Three dimensional printed fibrous interlocking interlayers

A three dimensional permeable thermoplastic tape useful for joining of layers of fiber tows (plies) together so as to form highly toughened resin infused structures. In one or more embodiments, the tape is manufactured using three dimensional printing and is applied between layers of fiber tows so as to tack the layers of fiber tows in place and prevent movement of the layers of fiber tows.
