Interest in additive manufacturing (AM) has gained considerable impetus over the past decade. One of the driving factor for AM success is the ability to create unique designs with intrinsic characteristics as, e.g., internal channels used for hydraulic components, cooling channels and heat exchangers. However, few of the main problems in internal channels manufactured by AM technologies are the high surface roughness obtained and the distortion of channel shape. In these design aspects there are still much to understand. In this study a cylindrical geometry for internal channels to be built with different angles with respect to the building plane in AlSi10Mg and Ti6Al4V alloys by Selective Laser Melting (SLM) was considered. The internal surfaces of the channels produced in both materials were analyzed by means of a surface roughness tester and by optical and electron microscopy to evaluate the effects of the material and design choices.
