Additive manufacturing will especially shine in the production of high performance parts that are not feasible to traditionally manufacture, such as small intricate parts. It is not uncommon for these parts to be in applications with important tolerances, and thus being able to reliably produce parts with expected part properties is of the upmost importance. If the scale of parts has an impact on part properties, much of the historical additive manufacturing research may not be applicable, causing produced parts to have vastly different part properties than expected. Here, we demonstrate a strong size effect on IN718 parts produced by powder bed fusion. In addition, different sets of parts were produced with varying print parameters including a traditionally manufactured set in an attempt to establish an idea on how to minimize the impact that scale has on AM parts by intelligently choosing print parameters.
