Combined Effects of Thermal Cycling Aging and Reinforcement Content on the Ball‐On‐Disk Wear of Additively Manufactured Polylactic Acid Composites

Polymer Composites, EarlyView.
Thermal Aging and Tribological Tests of Additive Manufactured PLA Composites. ABSTRACT This study focuses on the additive manufacturing of pure polylactic acid (PLA) specimens and milled glass fiber (GF)‐filled PLA composites under thermal cycling aging and wear tests. Wear tracks have been analyzed via 3D optical profiling and SEM imaging.

Robust β‐myrcene block copolymer elastomeric vitrimers

Polymer International, EarlyView.
Myrcene‐based vitrimeric elastomers were compared: statistical (poly(styrene‐stat‐myrcene‐stat‐AAEMA)] versus ‘hard–soft’ diblock (poly(styrene)‐block‐poly(myrcene‐co‐AAEMA)). The diblock's ability to anchor the glassy poly(styrene) blocks in a self‐assembled microstructure was effective – leading to four times higher tensile stress and ten times ...

Effects of autoclave sterilization on the dimensional stability of implant surgical guides: A 3D in vitro analysis

Journal of Prosthodontics, EarlyView.
Abstract Purpose Surgical guides are medical devices used in static implant surgery to replicate the prosthetic and surgical implant position planned with computer‐assisted software before surgery. Their use reduces invasiveness and improves safety and outcomes of implant surgery, provided that their accuracy is ensured from design to manufacturing and
