Investigation of forming organic based composites with 3d printer

According to the studies, it has been predicted that hexagonal boron nitride (hBN) can improve the printing quality of high-viscosity bioinks by making use of its bioinert, biocompatible, low coefficient of friction, and heat-homogeneous properties. It is aimed to eliminate the limitations by using hBN nanoparticles in 3D bioprinters and bioink variety. Viscosity changes were investigated by adding hBN nanoparticles to ionically bonded gelatin-chitosan bioinks, and printability was evaluated. It has been determined that high viscosity bioinks improve printability properties. Chemical (FTIR, DSC, XRD), physical (biodegradability, surface contact angle, water holding capacity), and biological (biocompatibility) tests were examined to evaluate the usability of the printed scaffolds as biomaterials with ionic or chemical cross-linking. Based on these results, it was determined that hBN nanoparticles included bioinks reduce the disadvantage of extrusion-based bioprinters. In addition, it has been determined that the superior properties of hBN nanoparticles can be utilized while developing composite biomaterials in the field of tissue engineering.
