Method for manufacturing a connecting part
11618084 · 2023-04-04 · ·

A method for manufacturing a connecting part includes a first portion having a threaded end that is able to be screwed to the end of a first tubular component for connecting the connecting part to said first tubular component, the method comprising a step of producing, by an additive manufacturing method, a second portion of the connecting part juxtaposed with the first portion having a threaded end. Moreover, the first portion having a threaded end is obtained by reworking the first portion on a separate tubular component of the connecting part in order to be joined to the connecting part.

Methods And System For Removal Of Powder From An Additively Manufactured Part

A system and method are disclosed for removal of unwanted material from additively manufactured parts by application of vibratory and/or acoustic energy. The system and method include a vibratory platform located in a chamber. Additively manufactured parts having unwanted material adhered thereto are placed on the vibratory platform. The platform is caused to vibrate thereby causing the unwanted material to detach from the parts. The system and method may also include the application of acoustic energy to cause unwanted material to detach from the parts. Advantageously, the unwanted material removed from the additively manufactured object can be recycled.

A method of forming a rod feedstock for titanium stir friction welding additive manufacturing may comprise: mixing a plurality of powdered metals comprising titanium, iron, vanadium, and aluminum to produce a powder blend; at least one of die pressing the powder blend to form a die pressed powder or continuously powder rolling the powder blend to form a die pressed powder; and sintering the powder blend to form a rod feedstock having a cross-sectional profile.

Inverted laser sintering systems for fabrication of additively-manufactured parts

Provided is an additive manufacturing process that uses an upward-pointing illumination source, such as a laser, projected through a substrate so as to solidify particulate matter supported by the substrate. The process is then repeated to build a hanging part layer by layer, for example by replenishing particulate matter on the substrate, or by moving the part a second substrate that supports other particulate matter. The disclosed process eliminates the need for a large powder bed and also allows for sintering of different powders in a single layer so as to give rise to parts that include layers that are themselves made from multiple materials. Also provided are related methods, include methods of incorporated cured resins into parts made by fusing particulate matter.
