  • Patent number: 10518469
    Abstract: The extraction of a three-dimensional (3D) object is facilitated using a printed hint, which includes an additional shape that is printed along with the 3D object in a granular-based printer bed. In example implementations, the hint is indicative of a location of the 3D object. In one example, a hint has a dimension indicative of a depth to the object in the printer bed. In another example, a position of a hint is indicative that the object is below, and a size of the hint is based on a size of the object. Some hints can also protect the object. Examples include plate and shell-shaped hints. The object is located under a plate hint or within a shell hint. Further, an appearance of the object or indications of the sturdiness of different parts of the object can be printed on the hint to facilitate a safe extraction of the object.

    Abstract: A method for forming three-dimensional anchoring structures on a surface is provided. This may result in a thermal barrier coating system exhibiting enhanced adherence for its constituent coatings. The method involves applying a laser beam (10) to a surface (12) of a solid material (14) to form a liquefied bed (16) on the surface of the solid material, then applying a pulse of laser energy (18) to a portion of the liquefied bed to cause a disturbance, such as a splash (20) or a wave (25) of liquefied material outside the liquefied bed. A three-dimensional anchoring structure (22) may thus be formed on the surface upon solidification of the splash or wave of liquefied material.

  • Patent number: 8967452
    Abstract: A die is prepared for thermal compression bonding by first aligning electrical contacts on the die to bond pads on a substrate onto which the die is to be mounted. Those electrical contacts are held against the bond pads on the substrate with a bonding tool. Partially bonding the die onto the substrate by providing heat to a portion of the die to elevate a temperature there to above a melting point of solder in the electrical contacts so as to melt at least some of the solder. Then thermally compress the whole die and heat it to above the melting point of the solder of the electrical contacts so that the solder of the electrical contacts outside the portion of the die are also melted to bond the die to the substrate.

  • Publication number: 20150053291
    Abstract: A method for manufacturing a fluid-leading component includes positioning a base element machined by a material-removing method with a planar upper face in a mounting support. The method at least includes the initial application of a layer section with predetermined dimensions of a particulate material in a predetermined region on the planar upper face of the base element; the heating of the layer section by a heat source in such a manner that the particles of the material within predetermined dimensions bond; and the application thereto and heating of at least one further layer section with predetermined dimensions of a particulate material in a predetermined region. In this way it is possible, in the generative manufacturing method, to obviate the need to provide support structures that subsequently have to be removed, and the base element is a functional part of the component to be manufactured.

  • Publication number: 20150034615
    Abstract: Methods, devices and systems for laser decoating of coated metal sheets, in particular for removing a metal protective layer from a metal sheet by a laser beam. The laser beam is directed onto a surface of a metal sheet coated with a metal protective layer, such that the laser beam strikes the surface of the metal sheet at a laser spot and melts material of the metal protective layer. A gas is directed by a plurality of nozzles at a pressure of at least 3 bar and at an acute angle with respect to the laser beam onto the laser spot. The nozzles are arranged around the laser beam such that the gas directed from the nozzles blows away the melted material of the metal protective layer from the metal sheet.
