| Abstract: |
| Porous titanium alloy bone implants are extensively utilized in the biomedical field due to their superior properties. Laser Beam Powder Bed Fusion (L-PBF), an advanced 3D printing technology, constructs material layer by layer, reducing manufacturing waste and enabling highly customized bone implant designs. This technology significantly enhances the ability to produce complex geometrical structures. However, the samples formed by L-PBF often retain a considerable amount of adhered powder on their surfaces, which severely affects their dimensional accuracy and surface quality. Consequently, there is a need for effective post-processing methods to remove this adhered powder. Chemical etching is a proven technique for such surface removal. |
