3D Printing for Jewelry: From Design to Cast Metal

Updated March 2026 · 8 min read

Castable resin costs $100-150 per liter and burns out cleanly for lost-wax casting. That's the standard workflow for custom jewelry: design in CAD, print in castable resin, cast in metal.

Direct metal printing exists but costs $5-20 per gram of metal. It's viable for high-end pieces or complex geometries that can't be cast, but for most jewelry, casting is cheaper and produces better surface finish.

This guide covers both workflows, what they cost, and when each makes sense.

The Lost-Wax Casting Workflow

This is how most custom jewelry is made in 2026. It's a centuries-old process with a modern twist: instead of hand-carving wax, you print it.

Step 1: CAD Design

Design your piece in jewelry CAD software (Rhino with Grasshopper, Matrix, Blender with jewelry plugins, or ZBrush for organic forms). Export as STL.

Design considerations:

Step 2: Print in Castable Resin

Castable resin is formulated to burn out completely during the casting process, leaving no ash residue that would contaminate the metal.

Print settings:

Printers that work:

A pendant-sized piece takes 2-4 hours to print. A ring takes 1-2 hours.

Castable resin costs: $100-150/liter. A ring uses 2-5ml of resin ($0.20-0.75 worth). A large pendant might use 20ml ($2-3).

Step 3: Post-Processing the Print

Washing: Remove uncured resin with isopropyl alcohol (IPA) or specialized resin cleaner. Wash for 5-10 minutes.

Curing: UV cure for 15-30 minutes. Under-curing leaves residue that causes casting defects. Over-curing makes the resin brittle and prone to cracking during burnout.

Support removal: Clip supports carefully. Sand contact points smooth with 400-grit or finer sandpaper. Any imperfection on the print shows up on the cast metal.

Inspection: Check for bubbles, layer lines, or defects. If the print isn't perfect, reprint. Fixing cast metal is harder than reprinting.

Step 4: Casting

Attach sprues: Wax sprues connect your print to the sprue base. This is how molten metal flows into the mold.

Invest the flask: Place your print (with sprues) into a metal cylinder (flask) and pour investment plaster around it. The investment hardens into a mold.

Burnout: Heat the flask to 700-1350°F (depending on metal). The castable resin burns out completely, leaving a cavity in the hardened investment.

Casting: Pour molten metal (gold, silver, platinum, bronze) into the flask. Centrifugal force or vacuum pulls the metal into every detail of the cavity.

Quench and divest: Cool the flask, break away the investment plaster, and you're left with a metal casting of your print.

Cost for casting service: $30-80 for silver, $80-200 for gold (depending on piece size and metal value). Most jewelry shops outsource this to a casting house unless they have in-house equipment.

Step 5: Finishing

Cast metal is rough. It needs finishing:

Filing and sanding: Remove sprue attachment points, smooth surfaces. Start with 400-grit, progress to 1200-grit or higher.

Polishing: Rotary tool with polishing compound brings metal to a mirror shine.

Stone setting: If the piece includes gemstones, set them now. This is skilled hand work.

Final polish: Tumbler or ultrasonic cleaner brings the piece to final finish.

Total finishing time: 2-10 hours depending on complexity.

Direct Metal Printing

Some high-end jewelry is printed directly in metal using DMLS (direct metal laser sintering) or binder jetting.

When to Print Metal Directly

Complex internal geometry: Lattices, hollow forms, or moving parts that can't be cast.

High-end custom pieces: Where the cost isn't a concern and you want the novelty of "metal 3D printed."

Production runs: If you're making 100+ identical pieces, metal printing can be cheaper than casting each one individually.

Materials that don't cast well: Titanium and stainless steel are hard to cast but print well.

Metal Printing Costs

Materials:

A 10-gram ring costs $50-100 in stainless, $150-300 in silver, $1,000-2,000 in gold.

Add $200-500 for machine time and setup, and $100-300 for finishing (polishing, stone setting).

Total cost for a metal-printed ring: $300-1,000 for stainless/silver, $1,500-3,000+ for gold/platinum.

Compare that to casting: $50-150 total for silver, $200-500 for gold (plus metal cost).

Metal printing makes sense for $2,000+ pieces or complex geometries. For most jewelry, casting is better.

Design Differences: Casting vs Metal Printing

Casting Design Rules

Draft angles: Need slight taper (1-3°) for stone setting tools to access prongs and bezels.

Thick enough to cast: 0.6-0.8mm walls minimum. Thinner sections might not fill during casting.

No overhangs: Everything needs to connect to the sprue tree. Unsupported features won't cast.

Surface finish: The print surface is the metal surface (after polishing). Smooth your print or live with texture on the metal.

Metal Printing Design Rules

Thin walls okay: 0.3-0.4mm walls are printable in metal. Allows for delicate filigree.

Overhangs need supports: Support material leaves marks that need to be polished out.

Shrinkage: Metal shrinks as it cools. Shops scale models up 1-3% to compensate, but check critical dimensions.

Porosity: Metal prints can have internal voids. Not usually a problem for jewelry but worth knowing.

Material Choices for Jewelry

Castable Resin (for casting workflow)

Standard castable resin: Burns out cleanly, $100-150/liter. Works for gold, silver, bronze, brass.

High-temp castable: For platinum and palladium casting (requires higher burnout temps). $150-250/liter.

Gray castable: Easier to see detail than clear/white resin. Same casting performance.

Direct Print Metals

Stainless steel (316L): Durable, hypoallergenic, cheap. Good for fashion jewelry and men's pieces.

Silver (925 sterling): Traditional jewelry metal. Prints well, finishes beautifully.

Gold (14k, 18k): Available but expensive. Most shops only offer this for confirmed high-value orders.

Platinum: Very expensive, very durable. Medical-grade hypoallergenic. Used for engagement rings and high-end pieces.

Titanium: Lightweight, hypoallergenic, modern look. Can be anodized for color. Popular for wedding bands.

Bronze/brass: Cheap, warm tone. Can be plated with gold or rhodium for a high-end look at lower cost.

Total per ring: $100-270 (after initial equipment investment)

Professional Service

Send your CAD file to a jewelry-focused 3D printing shop:

Print only: $10-30 per piece Print + casting: $80-200 for silver, $150-500 for gold Full service (print, cast, finish, set stones): $200-1,000 depending on complexity

For one-off custom pieces, using a service is cheaper than buying equipment. If you're making 20+ pieces a year, owning a printer pays off.

Complex Jewelry Techniques

Multi-Part Assemblies

Print components separately, cast them, then solder or rivet them together. Allows for mixed metals (silver body with gold accent) or moving parts (hinged lockets, kinetic jewelry).

Stone Settings

Print the setting, cast it, then set stones by hand. The CAD design needs clearance for the stone and prongs thick enough to hold it securely.

Prong settings: Print prongs 0.6-0.8mm thick. After casting, bend them over the stone and polish.

Bezel settings: Print a lip around the stone. After casting, fold the metal lip over the stone edge.

Channel settings: Print a channel, cast it, set stones in a row, and use a beading tool to secure them.

Textures and Patterns

Laser-engraved master: Print smooth, cast it, then laser engrave the metal. Allows for finer detail than you can print.

Printed texture: Model texture into the CAD, print it, cast it. Works for organic textures (bark, scales, hammered) but not fine engraving (text under 1mm tall won't cast clearly).

Surface treatments: After casting, apply patinas (chemical darkening), anodizing (titanium), or plating (gold/rhodium over silver/brass).

Common Mistakes and How to Avoid Them

Underestimating Finishing Time

A perfect cast still needs 2-6 hours of filing, sanding, and polishing to look professional. Budget time or money for this.

Too-Thin Walls

Designs that look fine on screen crack during burnout or don't fill during casting. Keep walls 0.8mm+ for rings, 0.6mm+ for pendants.

Bad Support Placement

Supports on visible surfaces leave marks. Place them on hidden areas (inside of ring band, back of pendant) or plan to polish them out.

Skipping Test Prints

Print a test piece, check dimensions and detail, then cast it. Cheaper than casting a bad print and discovering the design doesn't work.

Not Compensating for Shrinkage

Metal shrinks during cooling. A ring sized 7.0 in CAD might come out 6.9 after casting. Shops scale models up 1-2% to compensate, but check with your casting service.

Finding a Jewelry Printing Service

Look for shops that list jewelry as a specialty. They'll understand:

Questions to Ask

Alternative: Silicone Molding for Small Batch Production

If you need 10-50 copies of a design:

  1. Print one master in castable resin
  2. Cast it in metal
  3. Make a silicone mold of the metal casting
  4. Inject wax into the mold to create wax copies
  5. Cast the wax copies in metal

This is cheaper than printing 50 individual resin pieces, and the mold can be reused for years.

Cost: $50-150 for silicone mold, $3-8 per wax injection, $30-80 per casting. Economical at 10+ units.

High-Volume Production: Printing vs Traditional Methods

For 1-10 pieces:

3D print + cast. Cheapest and fastest.

For 10-100 pieces:

Silicone mold + cast. Avoids printing 100 resin pieces.

For 100-1,000 pieces:

Rubber mold or metal die. Traditional jewelry production methods are faster and cheaper at scale.

For 1,000+ pieces:

Die striking or investment casting with production tooling. 3D printing is only used for the master pattern.

3D printing revolutionized custom and small-batch jewelry. It didn't replace mass production—it made one-offs economically viable.

The Real Value for Jewelers

Before 3D printing, custom jewelry meant:

Now:

Total time: 2-4 days. Total cost: $50-250 depending on metal.

That's why half the custom jewelry industry switched to printed casting in the last 5 years. It's faster, cheaper, and gives designers geometric freedom they never had with hand-carving.

Learning CAD for Jewelry

If you're a jeweler considering 3D printing, the CAD learning curve is the real barrier, not the printing.

Easiest to learn:

Most powerful:

For organic forms:

Most jewelers hire a CAD designer for complex pieces and learn to do simple modifications themselves. Hourly CAD rates: $50-150/hour depending on complexity.

The Bottom Line

3D printing is standard practice for custom jewelry now. If you're not using it, you're competing with people who can deliver custom designs in a week for half your cost.

Print in castable resin, cast in metal, finish by hand. That workflow produces jewelry indistinguishable from hand-carved wax casting—because it's the same process, just with a printed master instead of a carved one.

Direct metal printing exists for high-end pieces and complex geometries, but it's expensive and niche. Most jewelers will never need it.
