Abstract
Disclosed embodiments include the formation of an article of manufacture by a process in which vibrations are generated in a bulk material disposed within a build chamber. The vibrations are focused within a section of the base material, and the focusing is controlled to cause the section of the base material to undergo a physical transformation to form at least a portion of the article of manufacture.
Claims9
A method of manufacturing, comprising:
- selectively forming an article of manufacture using focused excitation by a process comprising:
- generating vibrations in a base material disposed within a build chamber, wherein generating vibrations in the base material comprises directing an emission through a masking device to mask certain sections of the base material from being subjected to the emission, wherein the masking device comprises one or more screens having a matrix and a movable material, wherein the matrix is transmittive with respect to the emission and the movable material is substantially non-transmittive with respect to the emission;
- focusing the vibrations in a section of the base material;
- and
- controlling the focusing of the vibrations to cause the section of the base material to undergo a physical transformation to form at least a portion of the article of manufacture;
- and
- wherein directing the emission through the masking device comprises forming a pattern on the one or more screens corresponding to a portion of the article of manufacture using the movable material and directing the emission through the matrix while blocking the emission with the movable material wherein the emission is coherent light;
- wherein the masking device is configured to transduce the coherent light into a waveform;
- wherein focusing the vibrations on the section of the base material comprises adjusting the masking device to focus the waveform on a focal region corresponding to the section of the base material to undergo a physical transformation;
- and
- wherein the waveform is selected from the group consisting of infrasonic, sonic, and ultrasonic frequencies.
