Abstract
Embodiments are directed to nozzles for three-dimensional printing and related nozzle assemblies and methods. An example nozzle includes at least one top surface, at least one bottom surface, and at least one nozzle lateral surface extending from or near the top surface to or near the bottom surface. The nozzle also includes at least one conduit surface defining a conduit. At least a portion of the conduit surface comprise at least one of polycrystalline diamond (“PCD”), polycrystalline cubic boron nitride (“PcBN”), or another suitable superhard material. The nozzle may be attached to a base to form a nozzle assembly.
Claims20
A method of attaching a nozzle to a base to form a nozzle assembly for three-dimensional printing, the method comprising:
- providing the base defining a recess and a passageway extending from the recess to an exterior of the base, the base including at least one wall extending from the rest of the base, the at least one wall defining a portion of the recess;
- disposing the nozzle in the recess, the nozzle comprising:
- at least one top surface defining an orifice;
- at least one bottom surface opposite the at least one top surface, the at least one bottom surface defining an opening;
- at least one lateral surface;
- and
- at least one conduit surface defining a conduit, the at least one conduit surface extending from the orifice to the opening, at least a portion of the at least one conduit surface comprising at least one of polycrystalline diamond or polycrystalline cubic boron nitride, wherein the conduit of the nozzle is configured to be in fluid communication with the passageway when the nozzle is disposed in the recess;
- and
- deforming the at least one wall of the base, wherein the deforming attaches the nozzle to the base.
A method of attaching a nozzle to a base to form a nozzle assembly for three-dimensional printing, the method comprising:
- providing the base defining a recess and a passageway extending from the recess to an exterior of the base, the base including at least one wall defining a portion of the recess;
- disposing the nozzle in the recess, the nozzle comprising:
- at least one top surface defining an orifice;
- at least one bottom surface opposite the at least one top surface, the at least one bottom surface defining an opening;
- at least one lateral surface;
- at least one conduit surface defining a conduit, the at least one conduit surface extending from the orifice to the opening, at least a portion of the at least one conduit surface comprising a superhard material, wherein the conduit of the nozzle is configured to be in fluid communication with the passageway when the nozzle is disposed in the recess;
- and
- at least one chamfer extending between the at least one lateral surface and the at least one top surface and/or extending between the at least one conduit surface and the at least one top surface;
- and
- securing the nozzle to the base.
A method of attaching a nozzle to a base to form a nozzle assembly for three-dimensional printing, the method comprising:
- providing a base having a passageway through the base;
- forming a nozzle from a superhard material, the nozzle including a top surface, a bottom surface, a lateral surface, and an inner conduit surface defining a conduit through the nozzle;
- defining at least one chamfer on the nozzle between the lateral surface and the top surface and/or between the inner conduit surface and the top surface of the nozzle;
- and
- securing the nozzle in a recess defined in the base with a brazing material such that the conduit of the nozzle is in fluid communication with the passageway of the base.
