1. A method of manipulating a surface topology of an additively manufactured article, the method comprising:
determining a set of design objectives for an article;
assembling a set of candidate surface topology designs, each of the candidate surface topology designs comprising a candidate surface design to form a set of candidate surface designs;
quantifying a set of performance measurements of each of the set of candidate surface designs;
categorizing the set of candidate surface designs with respect to the set of design objectives;
selecting a first particular candidate surface design from the set of candidate surface designs, the first particular candidate surface design associated with a first particular article location of the article;
generating a first set of additive manufacturing specifications associated with the first particular article location; and
additively manufacturing the article to satisfy the first set of additive manufacturing specifications; wherein:
an additively manufactured article is produced.
