Investigation of electrochemical post-processing procedure for Ti-6Al-4V lattice structure manufactured by Direct Metal Laser Sintering (DMLS)

Additive manufacturing that is commonly called 3D printing has been identified as the 3rd industrial revolution because the outstanding flexibility that it brings to designer in the industry. Because the part is printed layer by layer, almost any complex geometry that can?t be made by conventional methods can be fabricated in a wide range of material like polymer, metal and ceramics. On the other hand, a major drawback of this technology limits its application in real engineering scenario in the industry and it?s the surface roughness of the printed part. Because of its rough surface, the mechanical properties of the printed geometry are considerably affected because the imperfections will tend to initiate crack propagation that will subsequently lead to the failure of the concerned part. This study will focus on 3d printed metal parts made from titanium because of its high importance in biomedical and aerospace applications. To solve the surface roughness problem, the post ? processing characterisation of the printed geometry need to be evaluated. TO BE CONT’D
