1. An additive manufacturing system having multiple components, comprising:
a high power laser to form a laser beam;
a beam dump including a fluid chamber having at least one laser transparent window into which the laser beam is directed;
a heat exchanger connected to the fluid chamber, with the heat exchanger acting to provide useful energy to at least one of the multiple components of the additive manufacturing system; and
an absorbing fluid circulated through the fluid chamber and the heat exchanger.
