1. IntroductionAdditive manufacturing (AM, also known as 3D printing or rapid prototyping) is recognized as a key strategy for manufacturing parts with complex structures. Selective laser melting (SLM) is a state-of-the-art AM process that can produce higher specific mechanical properties by sintering metallic powder with negligible void content [1]. However, metal parts produced by SLM often have high surface roughness.

1. IntroductionTitanium and its alloys are applied in a wide range of industries due to their outstanding mechanical and chemical properties, such as high strength/weight ratio, high elastic modulus, and excellent corrosion resistance. Specifically, the remarkable biocompatibility and good mechanical properties at elevated service temperatures make titanium alloys especially desirable for use in biomedical and aerospace industries, respectively [1,2].
