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.
