3D Bioplotter Research Papers

A high incidence of ureteral diseases was needed to find better treatments such as implanting ureteral stents. The existing ureteral stents produced a series of complications such as bacterial infection and biofilm after implantation. The fused deposition modeling (FDM) of 3D printing biodegradable antibacterial ureteral stents had gradually become the trend of clinical treatment. But it was necessary to optimize the FDM 3D printing parameters of biodegradable bacteriostatic materials to improve the precision and performance of manufacturing. In this study, polylactic-co-glycolic acid (PLGA), polycaprolactone (PCL), and nanosilver (AgNP) were mixed by the physical blending method, and the 3D printing parameters…

Ureteral stents are commonly used in clinical treatment of ureteral diseases. There were a series of complications, such as biofilms and crusts caused by bacteria after surgery. Therefore, biodegradable with bacteriostatic ureteral scaffolds would be the potential to solve above mentioned problems. In this study, nanosilver (AgNP) was added to the polylactic-co-glycolic acid (PLGA) and polycaprolactone (PCL) to prepare biodegradable antibacterial ureteral scaffold samples by 3D printing. The biocompatibility, antibacterial properties, degradability, and mechanical properties of samples were observed. The samples were under a strong inhibitory effect on both Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus), and the…
