Abstract: Based on author's experiences of using 3D printing,this paper addresses 3D printing technology and its impacts on contemporary art jewelry.The case study shows two application methods of this technology:developing its idiosyncrasies as formal elements,and employing CAD/3D printing as an alternative tool to traditional methods.The drawback of the graphic user interface(GUI)for craft practices,a problem related to CAD,is also discussed. CAD/3D printing has redefined the notion of "handcraft",and the constructive interaction between technology and art will promote CAD/3D printing as a more practical means for jewelry artists.
