Abstract

A contained radiation power metering system for measuring power of a radiation source of an additive manufacturing machine includes a base configured to fit within the additive manufacturing machine, a radiation sensor connected to the base and configured to receive radiation from the radiation source and output a radiation power signal, and a wireless module disposed on the base configured to receive the radiation power signal and transmit the radiation power signal from the system to a separate wireless receiver.

Claims (38)

1. A contained radiation power metering system for measuring power of a radiation source of an additive manufacturing machine, comprising:

a base configured to fit within the additive manufacturing machine;

a radiation sensor connected to the base and configured to directly receive radiation from the radiation source and output a radiation power signal; and

a wireless module disposed on the base configured to receive the radiation power signal and transmit the radiation power signal from the system to a separate wireless receiver, wherein the base, the radiation sensor, and the wireless module form a self-contained power metering system configured to pass through one or more seals and/or interlocks into an inert chamber of the additive manufacturing machine while maintaining the inert character of the chamber, wherein the base is configured to fit between a build plate and a powder bed of an additive manufacturing system and is configured to bolt to the additive manufacturing machine.

2. The system of claim 1 , further comprising an input adapter operatively connected to the radiation sensor to receive the radiation power signal for converting the radiation power signal from a first format to second format operable with the wireless module.

3. The system of claim 1 , further comprising a battery disposed on the base and in electrical communication with the wireless module and/or the radiation sensor.

4. The system of claim 3 , wherein the base is a cartridge plate and is configured to removably fit onto a build plate mount in the additive manufacturing machine.

5. The system of claim 4 , wherein the radiation sensor is mounted to the base on a post and is positioned relative to the base for focal length and centering position of the radiation source.

6. The system of claim 1 , further comprising a cooling system operatively connected to the radiation sensor to cool the radiation sensor.

7. The system of claim 6 , wherein the cooling system includes a coolant tank mounted to the base.

8. The system of claim 7 , wherein the cooling system includes a pump configured to pump coolant to the radiation sensor.

9. The system of claim 8 , wherein the radiation sensor is fluidly connected to the coolant tank via one or more coolant lines.

10. The system of claim 9 , wherein the one or more coolant lines includes a pump line and a return line.

11. The system of claim 10 , wherein the radiation sensor includes a housing with an internal volume configured to receive coolant.

12. The system of claim 1 , wherein the radiation sensor is laser power sensor.

13. A method for measuring the power of a radiation source of an additive manufacturing machine, comprising:

inserting a contained radiation power metering system into the machine;

sealing the contained radiation power metering system in the machine such that the contained radiation power metering system passes through one or more seals and/or interlocks into an inert chamber of the additive manufacturing machine while maintaining the inert character of the chamber;

irradiating a radiation sensor of the contained radiation power metering system with the radiation source; and

transmitting a wireless signal from the contained radiation power metering system within the machine to provide a reading of power of the radiation source,

wherein the radiation sensor is configured to directly receive radiation from the radiation source, wherein a base of the contained radiation power metering system is configured to fit between a build plate and a powder bed of an additive manufacturing system and is configured to bolt to the additive manufacturing machine.

14. The method of claim 13 , wherein the additive manufacturing machine is a powder bed fusion machine.

15. A contained radiation power metering system for measuring power of a radiation source of an additive manufacturing machine, comprising:

a base configured to fit within the additive manufacturing machine;

a radiation sensor connected to the base and configured to receive radiation from the radiation source and output a radiation power signal; and

a wireless module disposed on the base configured to receive the radiation power signal and transmit the radiation power signal from the system to a separate wireless receiver, wherein the base, the radiation sensor, and the wireless module form a self-contained power metering system configured to pass through one or more seals and/or interlocks into an inert chamber of the additive manufacturing machine while maintaining the inert character of the chamber, wherein the base is configured to fit between a build plate and a powder bed of an additive manufacturing system and is configured to bolt to the additive manufacturing machine.

16. The system of claim 15 , further comprising a battery disposed on the base and in electrical communication with the wireless module and/or the radiation sensor.

17. The system of claim 16 , wherein the radiation sensor is configured to directly receive radiation from the radiation source.

18. The system of claim 15 , wherein the base is a cartridge plate and is configured to removably fit onto a build plate mount in the additive manufacturing machine.

19. The system of claim 15 , further comprising, at least one of a battery disposed on the base and in electrical communication with the wireless module and/or the radiation sensor, and/or a cooling system operatively connected to the radiation sensor to cool the radiation sensor.

20. A contained radiation power metering system for measuring power of a radiation source of an additive manufacturing machine, comprising:

a base configured to fit within the additive manufacturing machine;

a radiation sensor connected to the base and configured to receive radiation from the radiation source and output a radiation power signal;

a wireless module disposed on the base configured to receive the radiation power signal and transmit the radiation power signal from the system to a separate wireless receiver;

at least one of:

a battery disposed on the base and in electrical communication with the wireless module and/or the radiation sensor; or

a cooling system operatively connected to the radiation sensor to cool the radiation sensor,

wherein the base is configured to fit between a build plate and a powder bed of an additive manufacturing system and is configured to bolt to the additive manufacturing machine.
