a promising technology and opened up newprospects for the product development. Nevertheless, designmethods remain predominantly based on conventional manufacturingprocesses and AM capabilities need to be bettermastered and integrated in the design team. This article questionshow a new technology (i.e. AM) can enable productinnovation. Thus to support designers in preliminary design,a methodology is introduced. The specificity of this methodologyis the use of a tailoredAMknowledge, i.e. a knowledgedelivered to the right user at the right time and in the rightformat, in order to be useful and usable during the creativestages of the design process
