  1. ( , Progress in Additive Manufacturing 2020)
    Shamsaei ‪Nima, Seifi ‪Mohsen (Ed.)
    Binder jet three-dimensional (3D) printing is a scalable, potentially low-cost additive manufacturing route able to process materials not attainable to other techniques, especially nonweldable materials. It relies on postprocess sintering to achieve final properties but encounters problems with distortion and cracking during sintering. The present work seeks to understand how part design geometry and 3D printing build orientation influence cracking during sintering, with the goal of mitigating the problem. In situ monitoring experiments reveal how sinter-cracks initiate and grow in 3D-printed notched panel specimens during densification. Different design geometries and build directions are tested to identify sinter-crack-resistant regimes.
