Abstract

Systems and methods for volumetrically fabricating 3D objects. The system includes at least a controller operably connected to a build volume and one or more energy sources. The build volume defines a volumetric buildable size of the object to be fabricated and includes media for fabricating the object therein. The energy source(s) is configured to emit at least a first and second energy beam therefrom. The controller is configured to direct the first and second emitted energy beams towards an intersecting point in the build volume to begin fabricating the media therein. The energy from each of the first and second beams is not sufficient to fabricate the object out of the media. The object is fabricated once multiple beams intersect, as collectively, the energy of the intersecting beams is sufficient to fabricate the object.

Dependent claims

A 3D volumetric printing system comprising:

a build volume (300) representative of a buildable size of an object to be fabricated and including media therein for fabricating the object;
a controller (200) operably connected to one or more energy sources (400) and configured to cause the one or more energy sources to emit at least a first and a second energy towards an intersecting point in the media such that the first and second emitted energies are collectively sufficient to fabricate the object from the media, wherein at least one of the energy sources is operable in a read mode, and wherein upon activating the read mode, the read mode energy source is configured to scan an interior of the build volume to determine a status of the object being fabricated, and wherein the controller is configured to adjust one or more parameters of the one or more energy sources based on the determined status to continue fabricating the object.

Dependencies are inferred from the claim text.
