Embodiment Construction

[0075] Embodiments will now be described with reference to the drawings. Signatures may, however, be implemented in many different forms and should not be construed as limitations to the illustrated embodiments described herein.

[0076] All documents mentioned herein are incorporated by reference in their entirety. Items described in the singular should be understood to include the plural, and vice versa, unless expressly described otherwise or clear from the text. The purpose of grammatical conjunctions is to denote any and all disjunctive and conjunctive combinations of connected phrases, sentences, words, etc., unless otherwise stated or clear from the context. Thus, the term "or" should generally be read to mean "and / or" and so on.

[0077] The description herein of ranges of values ​​is not limiting and represents individual substitution for any and all values ​​falling within that range, unless otherwise indicated herein, and each individual value within such range is...

Abstract

Devices, systems, and methods are directed to applying magnetohydrodynamic forces to liquid metal to eject liquid metal along a controlled pattern, such as a controlled three-dimensional pattern as part of additive manufacturing of an object. The magnetohydrodynamic force can be pulsed to eject droplets of the liquid metal to provide control over accuracy of the object being fabricated. The pulsations can be applied in fluid chambers having high resonance frequencies such that droplet ejection can be effectively controlled over a wide range of frequencies, including high frequencies suitable for liquid metal ejection at rates suitable for commercially viable three-dimensional fabrication.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit under 35 §119(e) of US Provisional Patent Application No. 62 / 303,341 filed March 3, 2016, the entire contents of which are hereby incorporated herein by reference. technical field [0003] The devices, systems, and methods described herein relate to the fabrication of magnetohydrodynamic (MHD) systems, and more particularly to magnetohydrodynamic systems for fabrication from metallic materials. Background technique [0004] Electric current can be combined with a magnetic field to impart MHD forces on the liquid metal. This force pushes the liquid metal to form metallic objects. Although MHD forces can be used to form metallic objects, issues related to speed, accuracy, control, and material properties pose challenges to using MHD forces for object formation in high volumes. Thus, there is a need for a commercially viable technique for metal fabrication using MHD forces. Contents...
