1. A method, comprising:
forming a sinterable first equipment part from a first material comprising a first sintering temperature;
forming a second equipment part from a second material comprising a second sintering temperature; and
joining the sinterable first equipment part to the second equipment part to form a monolithic equipment part by:
securing the sinterable first equipment part to the second equipment part; ramping a temperature of the sinterable first equipment part and the second equipment part to the first sintering temperature;
holding the temperature of the sinterable first equipment part and the second equipment part at the first sintering temperature;
ramping the temperature of the sinterable first equipment part and the second equipment part to the second sintering temperature; and
holding the temperature of the sinterable first equipment part and the second equipment part at the second sintering temperature;
wherein the sinterable first equipment part is formed from metal particles grouped together in a green body by additive manufacturing with a first density of the metal particles grouped together in the green body being substantially common throughout the green body, and wherein the sinterable first equipment part has different densities in different volumes of the sinterable first equipment part after sinterable first equipment part is joined to the second equipment part.
