Abstract
The present disclosure provides systems and methods for the formation of three-dimensional objects. A method for forming a three-dimensional object may comprise alternately and sequentially applying a stream comprising a binding substance to an area of a layer of powder material in a powder bed, and generating at least one perimeter of the three-dimensional object in the area. The stream may be applied in accordance with a model design of the three-dimensional object. The at least one perimeter may generated in accordance with the model design.
Claims20
A system for forming a three-dimensional object, comprising:
- a powder dispenser configured to deposit a powder material;
- a binding substance applicator configured to apply a binding substance to bind the deposited powder material, wherein the binding substance applicator comprises a binder tank that holds the binding substance and an ultrasonic mist generator system fluidically coupled to the binder tank to deliver the binding substance onto the deposited powder material when the binder tank is filled with the binding substance;
- and
- a perimeter generator configured to generate a perimeter by removing a portion of the powder material bound by the binding substance delivered by the ultrasonic mist generator system based on a model design of the three-dimensional object, thereby generating the three-dimensional object.
A method for generating a three-dimensional object, comprising depositing, by a powder dispenser, a layer of a powder material;
- applying, by a binding substance applicator, a binding substance to the layer of the powder material, wherein the binding substance applicator comprises a binder tank that holds the binding substance and an ultrasonic mist generator system fluidically coupled to the binder tank to deliver the binding substance onto the deposited powder material when the binder tank is filled with the binding substance;
- and
- generating, by a perimeter generator, a perimeter corresponding to the three-dimensional object by removing, based on a model design of the three-dimensional object, a portion of the layer including the powder material bound by the binding substance.
