Refractory metal and refractory metal carbide nanoparticle mixtures and methods for making the same are provided. The nanoparticle mixtures can be painted onto a surface to be coated and heated at low temperatures to form a gas-tight coating. The low temperature formation of refractory metal and refractory metal carbide coatings allows these coatings to be provided on surfaces that would otherwise be uncoatable or very difficult to coat, whether because they are carbon-based materials (e.g., graphite, carbon/carbon composites) or temperature sensitive materials (e.g., materials that would melt, oxidize, or otherwise not withstand temperatures above 800° C.), or because the high aspect ratio of the surface would prevent other coating methods from being effective (e.g., the inner surfaces of tubes and nozzles). The nanoparticle mixtures can also be disposed in a mold and sintered to form fully dense components.

Support Structures and Deposition Techniques for 3D Printing

Номер: US20130307193A1
Автор: Andrew Edwards, Chris Roberts Manners, Martin Alan Johnson
Принадлежит: 3D Systems Inc

There is provided a support structure for use with 3D printing of objects from computer-aided designs. The support structures include fine points that contact the down-facing surfaces of the 3D object being printed in order to adequately support the 3D object while also being adapted for easy removal after the 3D print process is complete. The fine points are possible by controlling the operation of the dispenser to provide a precise amount of material in a precise location. The dispenser jumps from a first fine point to a second fine point by retracting the print material after the first fine point is printed and then moving the dispenser vertically relative to the first fine point before the dispenser is moved horizontally to the second fine point.

Methods for Producing Coaxial Structures Using a Microfluidic Jet

Номер: US20140027952A1
Автор: David Bohling, David Michael Keicher, Fa-Gung Fan, Marcelino Essien
Принадлежит: INTEGRATED DEPOSITION SOLUTIONS Inc

The object of the invention is the provision of methods for controlled production of continuous multi-component filaments or discreet structures using a multi-component liquid jet issuing from an orifice. A multi-component jet consists of two or more liquids. The liquids may be miscible or immiscible, and form a co-axially propagating flow along the central axis of a flow cell. The working distance between the exit orifice and a substrate can be as large as 50 mm, so that in-flight processing of the jet is possible. The coaxial flow consists of an outer sheath liquid and an inner sample liquid or composite of liquids. The flow cell and the exit channel of the deposition head are heated so that the pressurized sheath liquid temperature is raised to near or above the boiling point of the sheath liquid at the local atmospheric pressure. The jet exits the deposition head through the orifice, and the outer liquid is evaporated as the jet falls at atmospheric pressure. The sheath liquid is processed thermally, optically, or chemically during flight to form a protective or insulating layer for the inner liquid or liquids. The inner liquids may contrastingly consist of an ultraviolet (UV) curable ink that is processed in-flight or after deposition. Since UV curable inks contain no volatile components, the coaxial jetted filament can be processed without producing cracks or bubbles in the sheath layer. Line widths are produced in the range from approximately 1 to 1000 microns.

FUNCTIONAL RAZOR CARTRIDGE

Принадлежит: THE GILLETTE COMPANY

A method of forming a functional razor cartridge for repeated shaving comprises rapid prototyping a housing of a razor cartridge. The housing has a front wall, a rear wall and opposing side walls disposed transverse to and between said front and rear walls. The method further comprises loading a metal insert with one or more elongate blade assemblies and disposing the metal insert in the housing such that the one or more blade assemblies extend between the opposing side walls of the housing. The present invention relates to a method of forming a functional razor cartridge using rapid prototyping, and a functional razor cartridge formed using rapid prototyping.Various forms of rapid prototyping are known for producing models or prototype parts. Rapid prototyping, or additive fabrication, takes virtual designs from e.g. computer aided design (CAD) programs and, using this data, builds a model of the design in a layered manner. One of the main advantages of using rapid prototyping/additive manufacturing is the ability to create almost any shape or geometric feature.As such, rapid prototyping is frequently used in the concept stage of products that are otherwise manufactured using more traditional molding techniques. As rapid prototype methods and materials have become more sophisticated, rapid prototyping is being used more often to make workable products, as opposed to making simply models.Rapid prototyping has been used in the fabrication of models of razor handles and cartridges for some time. However, these models have not had the requisite properties to enable them to be used for actual shaving, either because of inaccuracies in dimensions or because of the material that has been used. For example, materials used previously in the formation of model razor cartridges were unable to withstand exposure to hot water without changing in property. As a result, thus far razor cartridges made by rapid prototyping have been useful only for assessing the look, dimensions ...
