CPC Class B33Y

An implant and method for manufacturing an implant comprising an implant body defining a longitudinal axis and a structurally encoded pin contained within the implant body and aligned substantially along the longitudinal axis, the structurally encoded pin having a shape or surface characteristics discernable by an imaging modality such as x-ray, fluoroscopy, computed tomography, electromagnetic radiation, ultrasound, visible light, UV light, magnetic resonance imaging, positron emission tomography and neutron imaging, from outside the implant body, the shape or surface characteristics representing structurally encoded data. The structurally encoded pin is encoded via an electric discharge machining process.

A method and system provide an ophthalmic device including an optic and a haptic. The optic includes at least one optical material having a first Young's modulus. The haptic is coupled with the optic. The haptic includes at least a second Young's modulus greater than the first Young's modulus and less than 1.8 GPa. Thus, the haptic is stiffer than the optic, but more flexible than a material such as polymethyl metacrylate (PMMA).

A casting method includes constructing a 3D model to add an inner wall compensation quantity, making a thin shell mold by a 3D printing machine, individually treating the thin shell mold by smooth processing, processing the thin shell mold by multi-layer impregnation slurry or gunite to make an outer shell mold, and to form a double-layer shell mold which includes the thin shell mold and the outer shell mold, processing the double-layer shell mold by sand filling and compressing, clearing the thin shell mold by a physical or chemical process, casting the outer shell mold to form a shaped article, and post processing the shaped article by shaking and sand clearing to form a product.

Disclosed herein are surface-functionalized powders which alter the solidification of the melted powders. Some variations provide a powdered material comprising a plurality of particles fabricated from a first material, wherein each of the particles has a particle surface area that is continuously or intermittently surface-functionalized with nanoparticles and/or microparticles selected to control solidification of the powdered material from a liquid state to a solid state. Other variations provide a method of controlling solidification of a powdered material, comprising melting at least a portion of the powdered material to a liquid state, and semi-passively controlling solidification of the powdered material from the liquid state to a solid state. Several techniques for semi-passive control are described in detail. The methods may further include creating a structure through one or more techniques selected from additive manufacturing, injection molding, pressing and sintering, capacitive discharge sintering, or spark plasma sintering.

A device is disclosed for producing a three-dimensional object by layerwise construction. The device contains a flow device for generating a gas flow above an applied layer of the building material by means of a nozzle element for introducing the gas into the device. The nozzle element includes a body with a gas inlet side and a gas outlet side, and channels which penetrate the body from the gas inlet side to the gas outlet side, provided with inlet openings on the gas inlet side and gas outlet openings on the gas outlet side, and which are separated by walls. The length of the channels is selected such that a laminar flow is formed at the gas outlet side.

A carrier and at least one pin shaft of a gearbox of a wind turbine and method of manufacturing same includes forming the carrier and the pin shaft(s) as a single part or separate components. Further, the method includes forming one or more voids in the pin shaft(s) and/or the carrier via additive manufacturing. As such, the void(s) is configured to increase flexibility of the pin shaft(s)/carrier so as to improve a load distribution thereof.
