      "The goal of this research is to analyze the impact of chemical etching on parts produced by electron beam melting. Given that the surface conditions are poor (Ra between 25 to 35 µm), an enhancement of these is asked. Dimensional and surface measurements were realized on conceived parts. Different exposure times were tested. The impact of these times on surface quality was evaluated. To help ...

      "Additive manufacturing is feeding great hopes for future developments in fields such as aeronautical, biomedical and rapid tooling industrssssies. However, limitations are still restricting its use to make prototypes and hampering mass production. In the case of titanium alloy printing (e.g. Ti6Al4V) with the EBM (Electron Beam Melting) process, the major obstacle to use parts directly after printing ...
