Additive manufacturing (AM) is a technology that empowers engineers to design products of highly complex geometries and removes the numerous constraints of traditional manufacturing methods. In the aerospace industry, metal AM is quickly gaining a lot of attention because it enables new possibilities for weight optimization and functional integration. Despite the numerous benefits of AM, one of the main challenges to its use is the surface finish of the as-built part. Generally, the surface roughness of an AM part is far greater than that of a conventionally manufactured part. For many applications, this often means that post-processing techniques need to be employed to not only provide an optimal surface for functional or corrosion preventative purposes but also, in some contexts, to achieve an aesthetically pleasing part. The aim of this paper is to present an overview of current surface finish techniques advantages and limitations in relation to metal AM technologies.
