Despite the broad coverage concerning the technological challenges, little research has been performed
on the methods that enable designers to deal with Additive Manufacturing. At present, the challenge is to
generate Design for Additive Manufacturing knowledge which goes beyond traditional solutions and to ensure
that this knowledge is complete, correct and up to date. This paper reports on the employment of a wiki
environment to support open-ended knowledge management. We applied this solution in an undergraduate
prototyping course focused on exploring visual properties using AM structures. The results of the 32 students
encompass unexpected designs while the knowledge on the wiki encompassed i) AM processes, ii) procedures,
iii) artifacts. This forces us to rethink what should constitute DfAM.Mechanical Engineerin
