Valorization of Poplar Wood Wastes Into 3D‐Printed Soya Oil‐Based Composites by Vat Photopolymerization for Interior Design

Journal of Polymer Science, EarlyView.
Bio‐based polymer composites were 3D printed by LCD vat photopolymerization using acrylate epoxidized soybean oil as the monomer and isobornyl methacrylate as the reactive diluent. Two different poplar powders derived from plywood processing waste were incorporated within the photocurable formulations.

Computed tomographic assessment of plate offset in modified tibial plateau levelling osteotomy with a precontoured plate with an anatomical design for treatment of cranial cruciate ligament rupture and medial patellar luxation in small‐breed dogs: An in vitro study

Australian Veterinary Journal, EarlyView.
Aim To evaluate the effect of plate offset using a PCM‐TPLO plate with an anatomical design for medial translation of the proximal tibial segment and frontal‐plane alignment during modified TPLO in small‐breed canine tibial models using CT. Methods Five distinct small‐breed tibial morphologies were reproduced as three‐dimensional‐printed bone models ...

Flexo‐printable glucomannan‐based biofilm

Coloration Technology, EarlyView.
Abstract Biofilms were synthesised from glucomannan and xylan. The ratio of glucomannan: xylan varied from 90:10 (g/g) to 70:30 (g/g). Nanofibrillated cellulose was added to enhance the mechanical properties of the biofilms. In another approach, glucomannan/xylan suspensions were crosslinked with tartaric acid (TA) or citric acid (CA).

Biomechanical Analysis of 3D Printed and Thermoformed EVA Custom‐Made Mouthguard: Experimental and Finite Element Analyses

Dental Traumatology, EarlyView.
ABSTRACT Background/Objective 3D printed materials have been evaluated for fabricating mouthguards; however, little is known about their biomechanical performance in preventing dental trauma. This study aimed to compare two 3D printed polymers and three ethylene vinyl acetate (EVA) sheets used for mouthguard fabrication regarding their mechanical ...
