    摘要： Embodiments are directed to laser-based processes for forming features on the surface of a part. The feature may include a geometric element, a color element, and/or a surface finish element. In some cases, the laser-formed features are formed as a pattern of textured features that produce an aesthetic and/or tactile effect on the surface of the part. In some cases, the texture features may be sufficiently small that they may not be discerned by the unaided human eye. Also, in some cases, a multiple laser-based processes are combined to form a single feature or a finished part having a specific aesthetic and/or tactile effect.

    摘要： 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.

    摘要： Techniques or processes for providing markings on products are disclosed. The markings provided on products can be textual and/or graphic. The techniques or processes can provide high resolution markings on surfaces that are flat or curved. In one embodiment, the products have housings and the markings are to be provided on the housings. For example, the housing for a particular product can include an outer housing surface and the markings can be provided on the outer housing surface. The markings can be formed using a ultra-violet (UV) curable material that can be selectively cured on a surface (e.g., housing surface) in places where markings, namely text and/or graphics, are to be provided.

    摘要翻译： 公开了在产品上提供标记的技术或工艺。 产品上提供的标记可以是文字和/或图形。 这些技术或工艺可以在平坦或弯曲的表面上提供高分辨率的标记。 在一个实施例中，产品具有外壳，并且标记将设置在外壳上。 例如，用于特定产品的壳体可以包括外部壳体表面，并且标记可以设置在外部壳体表面上。 可以使用紫外线（UV）可固化材料形成标记，该材料可以在要提供标记即文本和/或图形的地方在表面（例如，外壳表面）上选择性固化。
