3D‐Printed Osteoinductive Polymeric Scaffolds with Optimized Architecture to Repair a Sheep Metatarsal Critical‐Size Bone Defect

Advanced Healthcare Materials, 2023
AbstractThe reconstruction of critical‐size bone defects in long bones remains a challenge for clinicians. A new osteoinductive medical device is developed here for long bone repair by combining a 3D‐printed architectured cylindrical scaffold made of clinical‐grade polylactic acid (PLA) with a polyelectrolyte film coating delivering the osteogenic bone

Polymer-Bioactive Glass Composite Filaments for 3D Scaffold Manufacturing by Fused Deposition Modeling: Fabrication and Characterization

Frontiers in Bioengineering and Biotechnology, 2020
Critical size bone defects are regularly treated by auto- and allograft transplantation. However, such treatments require to harvest bone from patient donor sites, with often limited tissue availability or risk of donor site morbidity. Not requiring bone

Preclinical Evaluation of 3D Printed Biomaterials for Repairing Critical-Size Bone Defects

, 2023
Problem and study aim: Millions of patients each year suffer from non-healing bone defects secondary to trauma, cancer, osteomyelitis, or congenital anomalies. The standard of care for managing these cases necessitates bone reconstruction surgery. Although using autologous bone (autograft) or banked cadaveric bone (allograft) has been considered the ...

Melt pool size control through multiple closed-loop modalities in laser-wire directed energy deposition of Ti-6Al-4V

, 2020
Sensing and closed-loop control are critical attributes of a robust 3D printing process, such as Directed Energy Deposition (DED), in which it is necessary to manage geometry, material properties, and residual stress and distortion.

Repair of Critical‐Sized Long Bone Defects Using Dipyridamole‐Augmented 3D‐Printed Bioactive Ceramic Scaffolds [PDF]

Journal of Orthopaedic Research, 2019
ABSTRACTThere are over two million long bone defects treated in the United States annually, of which ~5% will not heal without significant surgical intervention. While autogenous grafting is the standard of care in simple defects, a customized scaffold for large defects in unlimited quantities is not available.

Bridging the Loneliness Gap: Depression, Connectivity, and Isolation in Pediatric Oncology Patients and Their Peers

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Loneliness is associated with adverse physical and mental health outcomes and remains understudied in children and adolescents undergoing cancer therapy. Pediatric oncology patients may be at increased risk due to medical isolation and disruption of social networks.

Overcoming resolution vs. throughput trade-offs in ceramic material extrusion additive manufacturing via viscoelastic filament stretching

Virtual and Physical Prototyping
Fabricating large, monolithic ceramic parts using material-extrusion additive manufacturing remains challenging due to difficulty maintaining uniform moisture content during printing, which can lead to drying-induced defects such as warping and cracking,
