We have some progress to share with you about metal jewelry 3D printer limitation. We are focuses on the growth pattern which was inspired by coral's branching structure. every branch is growing at variable rates, density and thickens into complex configurations which mimic the natural forms of Acorpora corals. Through this generative jewelry design process, we aretrying to compare branch density vs branch thickness and find out more about the 3D printer limits. Also, through this process we will found which one is better candidate for polishing. We are using shapeway online printing service .
