Jewelry Casting House in Miami
Precision casting and 3D printing, held to a bench jeweler’s standard.
KNOX is a full-service jewelry casting house in Downtown Miami. We 3D print your designs in castable wax and cast them in gold, silver and platinum for designers, brands, stores and bench jewelers across Miami, Florida and beyond.
What we do
3D wax printing
Send us an STL and we print it in castable wax on production printers tuned for clean surfaces and sharp detail.
Lost-wax casting
10K, 14K and 18K gold in yellow, white and rose, 22K and 24K yellow gold, sterling silver 925 and platinum, cast in-house one flask at a time.
Cast your own models
Already have waxes or prints? Drop them off at our Flagler Street studio and we cast them on the same schedule.
Why jewelers choose KNOX
Built by jewelers, for jewelers. Every job runs through one team and one facility in Miami, from file to print to flask to pour, so nothing gets lost between vendors. Wax dropped off before 3 PM and STL files sent before 9 AM are ready the next business day, and rush 3D printing orders placed between 9 and 11 AM are ready the next business morning. You can follow every order in real time in your KNOX client portal, from upload to pickup.
