Abstract

Claims (44)

1. An additive manufacturing apparatus comprising:

a common resin support configured to support a first resin and a second resin, the first resin laterally offset from the second resin by a gap defined between the first resin and the second resin in a Y-axis direction;

a support plate including a window;

a stage configured to hold one or more cured layers of the first resin or the second resin to form a component positioned opposite the support plate;

a radiant energy device positioned on an opposite side of the common resin support from the stage and operable to generate and project radiant energy in a patterned image through the window;

an actuator assembly configured to move the stage in a Z-axis direction and in the Y-axis direction;

a frame operably coupled with the stage, the radiant energy device, and the support plate, the frame further coupled with a mounting plate; and

a first slide assembly, wherein the frame, the stage, the radiant energy device, and the support plate are moveable relative to the mounting plate along the first slide assembly.

2. The additive manufacturing apparatus of claim 1 , wherein an actuator of the actuator assembly is operably coupled with the frame and the mounting plate, and wherein the actuator is configured to move the frame between a first position and a second position along the first slide assembly.

3. The additive manufacturing apparatus of claim 1 , further comprising:

a second slide assembly operably coupled with the radiant energy device and the frame, wherein the radiant energy device is movable relative to the frame along the second slide assembly.

4. The additive manufacturing apparatus of claim 3 , further comprising:

a third actuator operably coupled with the frame and the radiant energy device, wherein the third actuator is configured to move the radiant energy device between a first position and a second position along the second slide assembly.

5. An additive manufacturing apparatus comprising:

a resin support configured to support a first resin and a second resin;

a support plate including a window;

a stage configured to hold one or more cured layers of the first resin or the second resin to form a component positioned opposite the support plate, wherein a working surface is defined by one of a surface of the stage or a surface of the component, and wherein the working surface is configured to contact the first resin and the second resin simultaneously;

a radiant energy device positioned on an opposite side of the resin support from the stage and operable to generate and project radiant energy in a patterned image through the window;

an actuator assembly configured to move the stage in a Z-axis direction and in a Y-axis direction; and

a frame operably coupled with the stage, the radiant energy device, and the actuator assembly, wherein the frame, the stage, and the radiant energy device are moveable relative to the support plate along a first slide assembly.

6. An additive manufacturing apparatus comprising:

a frame including a frame structure, the frame structure having a build plate, a support plate, and a base plate each coupled thereto, wherein the support plate includes a window therein;

a first actuator operably coupled with the build plate;

a print head operably coupled with the first actuator, wherein the first actuator is configured to move the print head relative to a Z-axis direction;

a stage operably coupled with the print head;

a radiant energy device operably coupled with the frame and positioned on an opposing side of the window from the stage in the Z-axis direction; and

a first slide assembly operably coupled with the base plate of the frame and a mounting plate, the first slide assembly configured to guide movement of the frame relative to the mounting plate in a Y-axis direction between a first curing position and a second curing position, wherein the window is configured to be aligned with a first portion of a resin support in the first curing position and a second portion of the resin support in the second curing position, the first portion offset from the second portion in the Y-axis direction.

7. The additive manufacturing apparatus of claim 6 , wherein the first slide assembly includes a track operably coupled with the mounting plate and one or more guides operably coupled with the base plate, the one or more guides slidable along the track.

8. The additive manufacturing apparatus of claim 6 , further comprising:

a second slide assembly positioned between the radiant energy device and the frame structure, the second slide assembly configured to guide movement of the radiant energy device relative to the window.

9. The additive manufacturing apparatus of claim 8 , wherein the second slide assembly includes a rail operably coupled with the frame structure and one or more guides, the one or more guides slidable along the rail.

10. The additive manufacturing apparatus of claim 5 , wherein an actuator of the actuator assembly is operably coupled with the frame and a mounting plate, and wherein the actuator is configured to move the frame between a first position and a second position along the first slide assembly.

11. The additive manufacturing apparatus of claim 5 , further comprising:

a second slide assembly operably coupled with the radiant energy device and the frame, wherein the radiant energy device is movable relative to the frame along the second slide assembly.

12. The additive manufacturing apparatus of claim 11 , further comprising:

a third actuator operably coupled with the frame and the radiant energy device, wherein the third actuator is configured to move the radiant energy device between a first position and a second position along the second slide assembly.

13. The additive manufacturing apparatus of claim 5 , further comprising:

one or more sensors configured to detect information related to a position of the frame.

14. The additive manufacturing apparatus of claim 5 , further comprising:

one or more sensors configured to detect information related to a position of the radiant energy device.

15. The additive manufacturing apparatus of claim 1 , further comprising:

one or more sensors configured to detect information related to a position of the frame.

16. The additive manufacturing apparatus of claim 1 , further comprising:

one or more sensors configured to detect information related to a position of the radiant energy device.
