Where Precious Metal Meets Additive Manufacturing
Gold 3D Print covers direct precious metal 3D printing — selective laser melting of gold, platinum, and silver powders to produce jewelry and luxury objects with geometry that lost-wax casting cannot achieve.
The technology enables: hollow forms that preserve visual volume while reducing metal content by 50–70%, interlocking mechanisms that print as a single assembled piece, filigree to 0.1 mm wall thickness, and personalized geometry from CAD files in 5–7 days.
The Case Against Casting for Complex Jewelry
Lost-wax casting dominates jewelry production for good reason — it produces excellent surface finish and works with any goldsmith’s existing tooling. But it has hard limits: enclosed hollow forms require multiple pieces, extremely thin filigree (< 0.3 mm) warps in the wax stage, and unique pieces require custom wax molds or hand carving.
