Find verified 3D printing shops specializing in wax patterns, castable resin, CAD modeling, and metal casting for jewelers across the US.
3D printing has transformed jewelry manufacturing over the past decade. Whether you're a bench jeweler creating one-of-a-kind pieces or a production shop running hundreds of castings per week, additive manufacturing gives you a faster path from CAD design to finished metal than traditional hand-carving ever could. Understanding the available processes — and what to look for in a printing partner — will help you get the best results.
Wax pattern printing (also called wax jetting or solid-state wax printing) produces direct casting waxes using specialized printers from manufacturers like Solidscape and 3D Systems. The output is a sacrificial wax model that burns out completely and cleanly in a standard investment casting flask — no ash residue, no expansion cracking. This is the closest digital equivalent to hand-carved wax and is the preferred method for fine jewelry where surface finish and dimensional accuracy are paramount. Typical layer resolution is 16–25 microns, producing surfaces that require minimal hand cleanup before investing. Wall thicknesses as thin as 0.5 mm are achievable on quality machines. Shops specializing in wax jetting generally price per piece (often $15–60 per model depending on size and complexity) rather than by weight.
Castable resin — printed on DLP or LCD photopolymer printers — has become the most widely accessible option for jewelry 3D printing. Resins marketed for jewelry casting (such as Formlabs Castable Wax or Photocentric Platinum Castable) are formulated to burn out at standard investment casting temperatures with minimal ash. The key advantage over wax jetting is cost: castable resin printers are far cheaper, so more shops offer the process. Resolution is excellent — many DLP printers print at 35–50 micron XY resolution, sufficient for all but the most intricate filigree. The tradeoff is burnout: resin requires a longer, more carefully managed burnout cycle than wax, and residue ash can contaminate gold alloys if not done correctly. When evaluating a shop, ask specifically whether they have experience with your alloy (yellow gold reacts differently than platinum) and whether their burnout schedule has been validated.
Direct metal laser sintering (DMLS) and selective laser melting (SLM) eliminate the casting step entirely by printing finished metal parts layer by layer from metal powder. For jewelry this means you can produce pieces in 18k gold, sterling silver, platinum, or titanium without a mold or flask. The benefits are compelling for complex geometries — internal lattices, interlocking structures, and undercuts that would be impossible to cast conventionally. The limitations are also real: surface finish from DMLS is rougher than a cast piece (typically 5–15 Ra µm), requiring post-machining or media tumbling; minimum feature size is larger than resin printing (typically 0.3–0.5 mm); and cost per piece is significantly higher. Direct metal printing makes the most sense for high-value production pieces, medical-grade implants, or designs where geometric complexity is the key design feature.
Not every 3D printing shop that lists "jewelry" as a capability has the process knowledge to back it up. When evaluating a partner, ask these questions:
Typical turnaround for wax or resin prints is 1–3 business days for the printed model. Add casting and finishing time — usually 3–7 additional days at a full-service shop — for a total of approximately one to two weeks from file to finished piece.
