The invention discloses a multi-material multi-scale 3D (3-dimensional) printing device provided with a single spray nozzle as well as a working method of the 3D printing device. The 3D printing device comprises a base, a work table, a bearing table, a substrate, a power supply, the spray nozzle and a bracket, wherein the base is mounted at the bottommost part, the bracket and the work table are mounted above the base, the spray nozzle is mounted on the bracket, the bearing table is fixed on the work table, and the substrate is fixed above the bearing table; an anode and a cathode of the power supply are connected with a nozzle body of the spray nozzle and the bearing table respectively; relative motion between the spray nozzle and the substrate in x, y and z directions is realized by the aid of relative motion between the work table and the bracket. The spray nozzle is provided with a plurality of feed openings connected with different trace feeding pumps, multiple materials are thoroughly mixed under the action of a stirrer after entering the spray nozzle, and multi-material printing is realized. The macroscopic geometrical shape as well as microstructures in an object and on the surface of the object is controlled reasonably, and multi-scale structural integrated manufacture is realized.

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.

Provided herein according to some embodiments is a method of forming a three-dimensional object, comprising: (a) forming a first intermediate object from a first polymerizable liquid; (b) forming a second intermediate object from a second polymerizable liquid; (c) optionally washing said first intermediate and said second intermediate; (d) contacting said first intermediate object to said second intermediate object; and then, (e) solidifying and / or curing a second solidifiable component (e.g., said second reactive component) in each of said first and second intermediate objects while said first and second intermediate objects are in contact with one another to couple said first and second intermediate objects to one another and form said three-dimensional object.

A method of making deflection members is disclosed. The deflection members are 3D objects that include cross-linkable polymers and are printed directly onto permeable materials utilizing at least two different printer settings.

A method and apparatus for making a three-dimensional object by solidifying a photohardenable material are shown and described. A photohardening inhibitor is admitted into a surface of a photohardenable material through a flexible film to create a “non-solidification zone” where little or no solidification occurs. The non-solidification zone prevents the exposed surface of the photohardenable material from solidifying in contact with the film. The inhibitor tends to cause the film to deform along the build axis, thereby creating a non-planar interface between the photohardenable material and the film, which distorts the resulting three-dimensional object. An apparatus is provided to stabilize the flexible film and eliminate or minimize such deformation.
