3D Bioplotter Research Papers

Three-dimensional (3D) bioprinting has emerged as a promising tool for fabricating scaffolds with highly accurate detailing and complex geometry of the net structures for tissue-engineered products. This study developed polylactic acid (PLA)-based composites by introducing graphene modified with alkyl ketene dimer (AKD) for multifunctional materials with a controllable structure by extrusion-based 3D bio-printing. Multilayer graphene was successfully synthesized by electrolytic exfoliation technique in poly (sodium 4-styrene sulfonate) (PSS) and ammonium sulfate ((NH4)2SO4) electrolyte solutions. The structures, morphology, and size of the synthesized GP were characterized by Raman spectroscopy, transmission electron microscopy (TEM), and scanning electron microscopy (SEM) analyses. The results…
