Part Deflection Measurements of AM?Bench IN718 3D Build Artifacts

Abstract

One of the primary barriers for adoption of additive manufacturing (AM) had been the uncertainty in the performance of AM parts due to residual stresses/strains. The rapid melting and solidification which occurs during AM processes result in high residual stresses/strains that produce significant part distortion. While efforts to mitigate residual stresses, such as post-process heat treatment, can reduce these effects, they nullify the benefits of the as-built component microstructure. Therefore, the ability to predict as-built component residual stresses and component deflection is crucial. AM-Bench seeks to provide modelers with high-fidelity data in well-characterized AM components to aid in model development and calibration. The measurements reported here are part of the 3D builds of nickel-based superalloy IN718 test objects for the CHAL-AMB2022-01-PD modeling challenges. The part deflection measurements were performed using a coordinate measurement machine after the part was partially separated from the build plate.
