Quasi-ductile to brittle transitional behavior and material properties gradient for additively manufactured SLA acrylate

•Quasi-ductile to brittle transitional behavior investigation of SLA acrylate.•Low curing energy leads to a ductile behavior and clean fracture surface.•High curing energy promotes a brittle behavior and rough fracture surface.•UV-curing creates a thickness-dependent material properties gradient.•Strain rate sensitivity is both a curing- and thickness-dependent variable.
