| Abstract Scope |
This study investigates the sintering behavior of stainless steel 316L components produced via binder jetting, focusing on how initial particles and pores distribution, gravity, and friction contribute to anisotropic shrinkage and shape distortions. Dilatometry tests were conducted to evaluate anisotropic shrinkage and microstructural changes at various sintering temperatures. The internal structure of printed parts was analyzed using X-ray computed tomography (CT), and anisotropic microstructural evolution during sintering was predicted through Monte Carlo simulations. The influence of gravity and friction was further explored by examining distortions in components with different geometries. A comprehensive sintering simulation framework is also presented, integrating the Rios–Olevsky–Hryha model and a constitutive law that incorporates material parameters to account for powder packing effects and the delta-ferrite phase transformation occurring at high temperatures. |
