Abstract

This paper gives insight into the limit of spreadability regarding Aluminium 7050 powder used in the promising Additive Manufacturing technique of SMS manufacturing, particularly focusing on the effects of changing powder grain size and scraper blade (shape and size). A method of testing these limits has been developed and implemented, showing that a finer Aluminium 7050 powder leads to a lower limit of spreadability, with application to SMS this allows the thinnest consistent layer of powder to be deposed leading to the production of higher resolution components.
