Artist/engineer Juliana Anzalone shares her personal experience using 3D printing to make objects in precious metal using lost wax casting. Lost wax casting is an ancient (6,000 years old) method of making metal parts from wax patterns. It is now possible to use 3D-printed wax in place of the traditionally hand-carved pattern. Ms. Anzalone purchased a Form2 3D printer in April 2019 with the intention of making prototypes for injection molded parts. The printer had the capability to print a castable wax material, but this feature was an afterthought until Ms. Anzalone met an enthusiastic member of a local lapidary guild who had been pining for the guild to get a 3D wax-printer. With the help of the local lapidary guild members, the Form2 proved to be an excellent tool for creating specific and precise CAD-based silversmithing pieces. This short lecture will explain the journey and the lessons learned to help future designers find their way to making custom precious metal items.
- Understand how to use a resin 3D printer to make lost wax metal parts
- Design a castable part,have a sense of what might work and what might fail,how to best sprue and orient the part
- Be inspired to find a local lapidary or community college facility to use as their foundry
