| Abstract Scope |
Production of complex part geometries is one of the major advantages of additive manufacturing (AM) over conventional manufacturing, however this can lead to different processing conditions in different regions of the final part. Characterising the effects of these changing conditions on mechanical properties can be challenging, since conventional tensile coupons often require relatively large samples. These witness coupons are often printed alongside a part and assumed to be representative of the whole part. The use of Profilometry-based Indentation Plastometry (PIP) allows this to be challenged through testing directly on the component itself. PIP has been used previously to study the presence of inhomogeneity and anisotropy in witness coupons; here, this work is expanded to include testing different regions of a single part. Comparisons are drawn with results from witness coupons. The use of PIP to characterise AM parts is shown to provide significant insights that are inaccessible via other methods. |
