Surface Modification of 3D Printed Biomedical Scaffolds Through an Electron Beam Processe

This study introduces a method for employing electron beam processing to effectuate both physical and chemical modifications to the surface of 3D printed biomedical scaffolds. Generally, 3D printed scaffolds exhibit certain limitations, including rough surface textures and dimensional inaccuracies, which hinder their applicability in medical contexts. To mitigate these issues, we implemented the electron beam technique to enhance surface smoothness and facilitate chemical alterations. The proposed method is not only efficient in polishing the surfaces of the printed scaffolds but also capable of processing a substantial number of samples within a brief timeframe. This technique holds potential for various biomedical implant devices and can be adapted for use with a range of metallic materials and polymer printing. Notably, the electron beam process described herein relies solely on heat treatment via electron application, thereby ensuring the complete elimination of any potential adverse effects that may arise during clinical trials related to the materials used.
