摘要:
A system such as a vehicle, building, vessel, aircraft, or electronic device system may have a layer of material with invisible laser-drilled openings. The layer of material may include an outer layer of fabric overlapping an inner layer such as an inner foam layer. Laser-drilled openings may include outer openings in the fabric layer and inner openings in the foam layer. Each of the inner openings may be overlapped by multiple outer openings. The exposed surface of the fabric layer may have strands of material of different appearances and/or may otherwise be configured to help visually hide the laser-drilled openings. Laser-drilled openings may also have small sizes to help make the laser-drilled openings invisible. Laser-drilled openings may overlap components such as audio components, heating and cooling components, and/or light-emitting components.

Embodiments described herein may take the form of a textile product having one or more regions of reduced density. These reduced density volumes may form one or more features in the product. For example, the reduced density volumes may have better acoustic transmission properties, optical transmission properties, flexibility, and the like. Sound transmission may be enhanced not only in terms of clarity, but also overall range. That is, certain audio frequencies that the textile may normally block when in an unaltered state may pass through a textile having reduced density or reduced density regions.

Substrates having laser textured surfaces and methods for forming the same are described. The methods involve using a laser to form three-dimensional features on a surface of the substrate. The laser three-dimensional features can be designed to interact with incident light to create unique visual effects. In some embodiments, the substrate is further treated with a pre-anodizing process and an anodizing process to form a protective metal oxide coating. In some cases, the type of pre-anodizing and anodizing process are chosen based on the geometry of the three-dimensional features and to enhance the visual effects.

Systems and methods for producing a textured pattern on a surface of a part using a laser. The part or laser may be rotated while forming the textured pattern to create a continuous textured pattern on a surface of a part. The continuous textured pattern may be substantially uniform over the entire pattern. A laser texturing system may also include an optical scanner. A first region of the surface of the part may be scanned using a first laser beam. One or more laser texturing parameters or a simulated geometric model may be created based on the scan of the first region. The textured pattern may be formed on the first region using a second laser beam. The textured pattern may be formed in accordance with the one or more laser texturing parameters or simulated geometric model.

Described herein are methods of constructing a three-dimensional part using metallic glass alloys, layer by layer, as well as metallic glass-forming materials designed for use therewith. In certain embodiments, a layer of metallic glass-forming powder or a sheet of metallic glass material is deposited to selected positions and then fused to a layer below by suitable methods such as laser heating or electron beam heating. The deposition and fusing are then repeated as need to construct the part, layer by layer. One or more sections or layers of non-metallic glass material can be included as needed to form composite parts. In one embodiment, the metallic glass-forming powder is a homogenous atomized powder. In another embodiment, the metallic glass-forming powder is formed by melting a metallic glass alloy to an over-heat threshold temperature substantially above the Tliquidus of the alloy, and quenching the melt at a high cooling rate such that the cooling material is kept substantially amorphous during cooling to form the metallic glass. In various embodiments, the melt is atomized during cooling to form the metallic glass-forming powder.

Described herein are methods of constructing a part having improved properties using metallic glass alloys, layer by layer. In accordance with certain aspects, a layer of metallic glass-forming powder is deposited to selected positions and then fused to a surface layer (i.e. layer below) by suitable methods such as laser heating or electron beam heating. The deposition and fusing are then repeated as need to construct the part, layer by layer. In certain embodiments, one or more sections or layers of non-metallic glass-forming material can be included as needed to form a composite final part. In certain aspects, the metallic glass-forming powder may be crystalized during depositing and fusing, or may be recrystallized during subsequent processing to provide selectively crystalized sections or layers, e.g., to impart desired functionality. In other aspects, non-metallic glass-forming materials may be deposited and fused at selected positions, e.g., to provide selective shear banding to impart improved ductile properties and plasticity. In yet other aspects, the metallic glass-forming powder or metallic glass material and non-metallic glass-forming material are deposited and fused to form a foam-like, bellow or similar structure, which is able to crumple under high stress to absorb energy under impact.

Markings on products are disclosed. In one embodiment, the products have housings and the markings are to be provided on the housings. For example, a housing for a particular product can include an outer housing surface and the markings can be provided on the outer housing surface so as to be visible from the outside of the housing. The markings may be precisely formed using a laser. Processing may be used to increase reflectivity of the markings.
