Do the printing orientation angle and layer thickness influence the radiopacity of 3D‐printed dental resins?

Journal of Prosthodontics, EarlyView.
Abstract Purpose This in vitro study aimed to evaluate the effect of layer thickness, printing orientation angle, and resin type on the radiopacity of 3D‐printed dental resins. Materials and Methods Three dental 3D‐printed resins (VarseoSmile TriniQ, Crowntec, and Primeprint Temp) were investigated using two‐layer thicknesses (50 and 100 µm) and three ...

Compatibility of Methacrylate Based Resins Controls Interfacial Failure and Toughness in 3D‐Printed Multimaterial Composites

Advanced Engineering Materials, Volume 28, Issue 15, 5 August 2026.
This work shows that the mechanical performance of multimaterial digital light processing (DLP) printed thermoset composites is governed by resin compatibility and interfacial design rather than spatial patterning alone. Brittle and ductile resin combinations produced premature interfacial failure, while graded interfaces and mechanically compatible ...
