I am thrilled to share our recent collaboration with BAM Germany Bundesanstalt für Materialforschung und -prüfung, published in the journal Materials & Design! I would like to thank all the coauthors for a great collaboration: Tatiana Mishurova, Laura Cordova, Mats Persson, Giovanni BRUNO, Eugene Olevsky, and Eduard Hryha. Characterizing the sintering process has been challenging due to the high porosity and fragility of green compacts. Our research addresses this gap by employing high-resolution synchrotron X-ray computed tomography (SXCT) on BJT 316L samples from ex-situ interrupted sintering tests. We identified periodic density fluctuations along the building direction, directly linked to the original printing layer thickness and its reduction during sintering. Utilizing a BJT-specific continuum sintering model, we replicated density evolution and captured the fluctuation decrease from green (1.66%) to sintered (0.56%) state. This research offers valuable insights for optimizing BJT printing and sintering parameters, ultimately leading to more robust and reliable BJT components. Our findings pave the way for further investigations into the influence of printing parameters, powder properties, and sintering strategies on density evolution.
