Abstract

Additively manufactured channels enable conformal cooling for applications such as injection molds or fuel injectors. Understanding the scalability of these channels for applications of different sizes is essential to pave the way for a more widespread adoption. This work uses a non-destructive testing approach to characterize and compare channels of different sizes made by two popular Metal Additive Manufacturing (MAM) technologies: Binder Jetting (BJ) and Laser Powder Bed Fusion (LPBF). The results reveal systematic differences in deviations depending on the nominal diameter and the used AM process.
