Abstract

An apparatus for hybrid manufacturing comprising a frame, a build plate that is adapted to move relative to the frame, a material pump that is adapted to pump one or more materials, a mixing head that is adapted to mix the one or more materials, a mixing hose that is in fluid communication with the material pump and the mixing head, a pump that is adapted to remove air from or introduce air into a mold, a hose that is in fluid communication with the pump and the mold, a vat that is adapted to retain a liquid, and a radiation source that is disposed adjacent to the vat. The apparatus prints the mold and fills the mold. A method comprising printing the mold with material(s), removing air from or introducing air into the mold, filling the mold with one or more primary materials, and dissolving the mold.

Claims21

Dependent claims

A method for hybrid manufacturing, said method comprising:

a. providing an apparatus for hybrid manufacturing, said apparatus comprising:
(i) a frame;
(ii) a build plate, said build plate being adapted to move relative to the frame;
(iii) a material pump, said material pump being adapted to pump one or more materials;
(iv) a first mixing hose, said first mixing hose being in fluid communication with the material pump;
(v) a positive or negative (pressure differential) gas pressure pump, said positive or negative (pressure differential) gas pressure pump being adapted to remove air from or introduce air into a mold;
(vi) a first positive or negative (pressure differential) gas pressure hose, said first positive or negative (pressure differential) gas pressure hose being in fluid communication with the positive or negative (pressure differential) gas pressure pump;
(vii) a vat;
said vat being adapted to retain a liquid;
(viii) a radiation source, said radiation source being disposed adjacent to the vat;
b. providing a mixing head, a second mixing hose, and a second positive or negative (pressure differential) gas pressure hose that are in fluid communication, wherein the mixing head and the second positive or negative (pressure differential) gas pressure hose are connected with openings of the build plate;
c. printing the mold with one or more mold materials such that the second mixing hose and the second positive or negative (pressure differential) gas pressure hose are connected with the mold;
d. removing air from or introducing air into the mold;
e. filling the mold with the one or more primary materials;
f. dissolving the mold;
wherein the apparatus for hybrid manufacturing prints the mold and fills the mold.
