1. A system for stress relief in forming a product by additive manufacturing, the system comprising:
a build surface;
a stress relief system including a transducer coupled with the build surface, the transducer configured to generate a frequency and a power so the stress relief system is configured to deliver stress relief energy to the build surface;
a material delivery system configured to add successive layers of a material to build the product on the build surface;
an energy system configured to add build energy to incorporate the material of each of the successive layers into the product; and
at least one controller configured to:
coordinate operation of the stress relief system, the material delivery system and the energy system to complete the build of the product;
determine stress relief parameters throughout the build of the product, where the stress relief parameters include frequency and amplitude parameters and are at least one of predetermined or based on input from at least one sensor;
determine, by a processor of the at least one controller and based on the stress relief parameters, where, during the build of the product, stress relief is required based on where a deviation from design parameters of the product is indicated as incipient or actual; and
apply, by the transducer of the stress relief system and when the processor has determined that the stress relief is required, an input to the stress relief system with a power level tailored to relieve stress according to the stress relief parameters as determined by the at least one controller.
