1. A method of constructing an additive manufactured multi-portion article, comprising:
additive manufacturing a first portion of the multi-portion article with a first additive manufacturing process;
additive manufacturing a second portion of the multi-portion article with a second additive manufacturing process different than the first additive manufacturing process; and
mechanically attaching the second portion to the first portion at an integral joining geometry, wherein the first additive manufacturing process is of a higher resolution than the second additive manufacturing process and the first additive manufacturing process operates at a different volumetric build rate than the second additive manufacturing process, the second portion forms a majority portion of the multi-portion article.
