Localized heating to improve interlayer bonding in 3D printing

The present disclosure provides methods for printing at least a portion of a three-dimensional (3D) object, comprising receiving, in computer memory, a model of the 3D object. Next, at least one filament material from a source of the at least one filament material may be directed towards a substrate...

Zusammenfassung:	The present disclosure provides methods for printing at least a portion of a three-dimensional (3D) object, comprising receiving, in computer memory, a model of the 3D object. Next, at least one filament material from a source of the at least one filament material may be directed towards a substrate that is configured to support the 3D object, thereby depositing a first layer corresponding to a portion of the 3D object adjacent to the substrate. A second layer corresponding to at least a portion of the 3D object may be deposited. The first and second layer may be deposited in accordance with the model of the 3D object. At least a first energy beam from at least one energy source may be used to selectively melt at least a portion of the first layer and/or the second layer, thereby forming at least a portion of the 3D object.
