Abstract

Automated multi-layer two-dimensional printing is provided via a plurality of supply tanks; a deposition tank; a plurality of pumps each comprising: a pipeline in fluid communication with one supply tank and the deposition tank on opposing ends; a bearing holder, including a plurality of rotatable bearings arranged at a shared angle to each other relative to an axis of rotation for the bearing holder; a housing wall, wherein at least a subset of the plurality of rotatable bearings compresses the pipeline against the housing wall; and a motor configured to rotate the bearing holder about the axis of rotation and push a fluid through the pipeline by moving the plurality of rotatable bearings about the axis of rotation to change where the rotatable bearings compress the pipeline against the housing wall; and a spray deposition nozzle in fluid communication with the deposition tank.

First claim

The invention is claimed as follows:

1 . A device, comprising:
a plurality of supply tanks; a deposition tank; a plurality of pumps, each pump of the plurality of pumps connected to one supply tank of the plurality of supply tanks and to the deposition tank, each pump of the plurality of pumps comprising:
a pipeline in fluid communication with the one supply tank of the plurality of supply tank and in fluid communication with the deposition tank on opposing ends;
a bearing holder, including a plurality of rotatable bearings arranged at a shared angle to each other relative to an axis of rotation for the bearing holder;
a housing wall, wherein at least a subset of the plurality of rotatable bearings compresses the pipeline against the housing wall; and
a stepper motor, connected to the bearing holder, configured to rotate the bearing holder about the axis of rotation and push a fluid through the pipeline by moving the plurality of rotatable bearings about the axis of rotation to change where the rotatable bearings compress the pipeline against the housing wall; and
a spray deposition nozzle in fluid communication with the deposition tank.

2 . The device of claim 1 , wherein the spray deposition nozzle is selectively replaceable for a second spray deposition nozzle with a different bore.

3 . The device of claim 1 , further comprising:
an inert gas supply; a gas supply line in communication with the inert gas supply and the deposition tank; and a gas control valve that in a first state prevents release of gas from the inert gas supply into deposition tank and in a second state permits release of the gas.

4 . The device of claim 1 , further comprising:
a positional motor having at least two degrees of freedom of movement relative to a deposition surface; and a controller that executes instructions to activate the positional motor to adjust a location of the spray deposition nozzle relative to the deposition surface according to the at least two degrees of freedom.

5 . The device of claim 4 , further comprising:
a laser thickness gauge, in communication with the controller.

6 . The device of claim 1 , further comprising:
a cleaning supply; a cleaning supply line in communication with the cleaning supply and the deposition tank; and a cleaning pump that delivers a cleaning solution from the cleaning supply to the deposition tank via the cleaning supply line in a first state and prevents the cleaning solution from being delivered to the deposition tank in a second state.

7 . The device of claim 1 , each pump of the plurality of pumps has a first mode of operation that supplies a material to the deposition tank from a corresponding supply tank of the plurality of supply tanks and a second mode of operation that retracts the material from the deposition tank for return to the corresponding supply tank.

8 . The device of claim 1 , wherein each supply tank of the plurality of supply tanks holds a different material.

9 . The device of claim 1 , wherein the plurality of rotatable bearings consists of four bearings, wherein at least three of the four bearings at any time compress the pipeline against the housing wall.

10 . The device of claim 1 , wherein each rotatable bearing of the plurality of rotatable bearings is free to rotate about a corresponding bearing axis parallel to the axis of rotation.

11 . A pump, comprising:
a flexible pipeline; a bearing holder, including a plurality of rotatable bearings arranged at a shared angle to each other relative to an axis of rotation for the bearing holder; a housing wall, wherein at least a subset of the plurality of rotatable bearings compresses the flexible pipeline against the housing wall; and a stepper motor, connected to the axis of rotation for the bearing holder, configured to rotate the bearing holder about the axis of rotation and push a fluid through the flexible pipeline by moving the plurality of rotatable bearings about the axis of rotation to change where the rotatable bearings compress the flexible pipeline against the housing wall.

12 . The pump of claim 11 , wherein the flexible pipeline of the pump is connected to a first supply tank and a deposition tank, and wherein a second pump, connected to a second supply tank, is also connected to the deposition tank.

13 . The pump of claim 11 , wherein the plurality of rotatable bearings consists of four bearings, wherein at least three of the four bearing at any time compress the flexible pipeline against the housing wall.
