Leveler for 3D printing build plate thermal expansion
An apparatus, system and method for limiting build plate expansion in a 3D print environment. The apparatus, system and method may include a decoupling leveler associated with mounts for a build plate in the print environment; and a plurality of adjustments passing substantially through and mounted within the decoupling leveler. The leveler may be decoupled from the mounts during heating and cooling of the print environment, and recoupled via a positional clamped by the plurality of adjustments during printing on the build plate.
1. A limiter for build plate expansion in a 3D print environment, comprising:
a build plate adjustment system associated with mounts for a build plate in the print environment; and
a plurality of adjustments passing substantially through and mounted within the build plate adjustment system;
wherein the build plate adjustment system is configured to be actuated via a vertical movement of the build plate causing an addition of or a removal of a load on at least one load switch point of the build plate adjustment system.
2. The limiter of claim 1 , wherein the plurality of adjustments comprises spring loaded clamps.
3. The limiter of claim 1 , wherein the plurality of adjustments comprise three adjustments.
4. The limiter of claim 1 , wherein the build plate adjustment system is actuated during a heating or a cooling of the print environment.
5. The limiter of claim 1 , wherein the build plate is steel.
6. The limiter of claim 1 , wherein the build plate is about 500×500 mm.
7. The limiter of claim 1 , wherein the expansion is about 0.040 inches.
8. The limiter of claim 1 , wherein each of the plurality of adjustments lacks a wear point.
9. The limiter of claim 1 , wherein the addition of or the removal of the load is manual.
10. The limiter of claim 1 , wherein the addition of or the removal of the load counteracts a spring constant.
11. The limiter of claim 1 , wherein the actuation of the build plate adjustment system is automated.
12. The limiter of claim 1 , wherein the plurality of adjustments comprise yaw, pitch and roll adjustments.
13. The limiter of claim 12 , wherein the plurality of adjustments is present within a kinematic mount.
14. The limiter of claim 13 , wherein the plurality of adjustments comprise screws through the kinematic mount in conjunction with kinematic balls responsive to turning of the screws.
15. The limiter of claim 1 , further comprising at least one sensor capable of sensing a distance from the build plate to an output of the print.
16. The limiter of claim 15 , wherein the at least one sensor comprises a three position sensor.
17. The limiter of claim 16 , further comprising a processing system capable of applying a leveling algorithm, including at least an averaging algorithm, to data output by the sensor.
18. The limiter of claim 1 , wherein a heater for the print environment is turned on and off in conjunction with the actuation of the build plate adjustment system during the print.
19. The limiter of claim 1 , wherein a portion of the build plate adjustment system is locked to the build plate.
