Zusammenfassung:	A method of making an article includes coating an article formed using an additive manufacturing process technique, such as with laser sintering or a powder bed fusion technique. Pressure is thereafter applied to the coating and one or more surface-connected pores defined within the article are closed with the pressure. The coating is thereafter removed from the article.
