Influence of degree of conversion on the cytotoxicity of 3D‐printed denture base resins. A scoping review

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose Evidence regarding the cytotoxicity of 3D‐printed denture base resins and the role of degree of conversion remains limited and heterogeneous. Therefore, this scoping review aimed to map existing in vitro evidence and explore how degree of conversion and post‐processing factors are reported in relation to biological outcomes.

Flexural Performance and Morphological Characterization of Graphene Nanoparticle‐Reinforced Polylactic Acid (PLA) Nanocomposites

open access: yesJournal of Polymer Science, Volume 64, Issue 16, Page 3427-3441, 15 August 2026.
PLA/GNP filaments containing 0–1.6 wt% graphene are produced by melt compounding and fabricated into flexural specimens using FDM. Their mechanical response and fracture morphology are evaluated through ASTM D790 three‐point bending tests and SEM. Increasing graphene loading promotes agglomeration and interlayer defects, reducing strength, stiffness ...

Soft Mechanical‐Electrical Logic Using Liquid Metal‐Filled 3D‐Printed Architectures

open access: yesAdvanced Engineering Materials, Volume 28, Issue 15, 5 August 2026.
We present 3D‐printed soft mechanical–electrical logic elements that use liquid metal–filled silicone tubes actuated by thermoplastic polyurethane/polylactic acid (TPU/PLA) architectures to produce Boolean operations. Complementary normally open and normally closed unit cells perform repeatable binary transitions and can be combined into more complex ...
