3D Printing: Additive Manufacturing and Performance of Architectured Cement‐Based Materials (Adv. Mater. 43/2018)

3D-printed architectured cement-based materials exhibit improved mechanical properties compared to their cast counterparts. The presence of heterogeneous interfaces, combined with engineered architecture, promotes development of unique damage mechanisms, such as interfacial cracking and crack twisting, which lead to damage delocalization. This delocalization can be energetically favorable, thus resulting in more efficient energy dissipation, promotion of toughening and increase in damage tolerance, all without sacrificing the strength, as described by Pablo D. Zavattieri and co-workers in article number 1802123.
