Innovations in powder materials for binder jetting

Additive manufacturing has evolved from a prototyping tool to a primary method for producing functional, end-use products. Binder jetting, in particular, has gained significant attention in the construction industry. This paper reviews innovative powder material mixes used in binder jetting techniques. These materials, combined with modifications to printing parameters such as layer thickness and binder saturation level, offer improvements in mechanical strength, dimensional accuracy, and the sustainability of 3D-printed objects. The review highlights recent experimental studies that investigate the effects of powder composition, binder saturation, and post-processing techniques. The findings provide insights into optimizing material behavior and mechanical performance for construction-grade applications.
