Experience cost-effective innovation that turns your boldest designs into durable, high-quality gold parts—redefining what’s possible in luxury, tech, and beyond.
What Is Gold 3D Printing?
Stampa 3D in oro is a specialized produzione additiva process that transforms oro (in powder form) into functional or decorative parts through layer-by-layer fabrication. Unlike traditional goldworking methods (per esempio., casting, forgiatura), it follows a clear process definition: using digital designs to guide machines that melt or bind gold feedstock into precise, three-dimensional objects.
Al suo centro, this technology leverages gold’s unique material composition—including its malleability, resistenza alla corrosione, and aesthetic appeal—while unlocking design freedom that traditional methods can’t match. Whether using pure gold (24K) for luxury jewelry or gold alloys (per esempio., 18K gold + rame) for enhanced strength in electronics, gold 3D printing bridges the gap between artistry and engineering.
Key Basics of Gold 3D Printing:
| Term | Description | Role in the Process |
| Pure Gold (24K) | 99.9% oro, soft, high luster | Luxury jewelry, pezzi d'arte, decorative components |
| Gold Alloys | Blends of gold with metals like copper, argento, or palladium (per esempio., 18K = 75% oro) | Electronics connectors, dispositivi medici, durable jewelry |
| Additive Manufacturing for Gold | Uses high-precision techniques (per esempio., SLM, binder jetting) to avoid gold waste | Ensures cost-effectiveness, even for high-value gold materials |

Processo: The Step-by-Step Workflow for Gold 3D Printing
Our Gold 3D Printing process is a structured, meticulous workflow that accounts for gold’s high value and unique properties (per esempio., low melting point: 1,064°C) to ensure efficiency and quality:
- Progetto & Modeling:
- Collaborate with our team to finalize your digital design (CAD model), optimizing it for gold—e.g., minimizing support structures (to reduce gold waste) and ensuring fine details (per esempio., jewelry engravings) are print-ready.
- Convert the CAD model to an STL file, compatible with our advanced slicing software (per esempio., Magics, Simplify3D).
- Print Preparation:
- The slicer breaks the model into ultra-thin layers (0.01–0.05mm for jewelry, 0.05–0.1mm for electronics) and sets parameters (per esempio., SLM laser power: 100–200W for gold powder).
- Prepare gold metal powders (particle size: 5–45μm)—we use spherical powders for uniform melting and minimal waste.
- Printing Phase:
- The most common techniques for gold are Fusione laser selettiva (SLM) (for dense, high-strength parts like electronics) E Binder Jetting (for cost-effective, detailed jewelry). SLM melts gold powder layer by layer, while binder jetting uses a liquid binder to form green parts (sintered later).
- Post-elaborazione:
- Sintering (for binder jetting): Green parts are heated to 800–900°C to fuse gold particles, increasing density and strength.
- Support Removal: Carefully remove minimal supports (using ultrasonic cleaning or manual tools) to avoid damaging delicate gold parts.
- Finitura: Perform polishing, placcatura, or texturing to achieve the desired aesthetic (per esempio., mirror polish for jewelry, matte finish for electronics).
- Controllo qualità:
Every part undergoes rigorous inspection:
- Laser scanners to verify precisione dimensionale and detail precision.
- Density testing (via Archimedes’ principle) to ensure gold purity and part integrity.
Visual inspection to confirm aesthetic standards (per esempio., luster, struttura).
Materiali: Choosing the Right Gold for Your Project
Not all gold materials are the same—we offer a range of options to match your application’s aesthetic, funzionale, and budget needs:
| Material Type | Key Properties | Ideal Applications |
| 24K Pure Gold Powder | 99.9% oro, soft (2.5 Mohs hardness), high luster | Luxury jewelry (rings, necklaces), pezzi d'arte, decorative components |
| 18K Gold Alloy (75% Au + 25% Cu) | Harder than 24K (3.5 Mohs), warm rose hue, durable | Everyday jewelry, watch cases, electronics connectors |
| 14K Gold Alloy (58.3% Au + 41.7% Ag/Cu) | High strength (4 Mohs), conveniente, versatile | Medical devices (dental crowns), assetto automobilistico, high-volume jewelry |
| White Gold Alloy (75% Au + 25% Pd/Ni) | Silvery-white appearance, corrosion-resistant | Luxury jewelry (engagement rings), electronics components requiring neutral color |
| Gold-Plated Composites | Base metal (per esempio., titanium) with 3D-printed gold layer | Cost-sensitive applications (decorative electronics, promotional items) |
We ensure material compatibility—all our gold powders work seamlessly with our printing techniques, and we provide material samples for testing (per esempio., to verify color or hardness) before full production.
Trattamento superficiale: Enhancing Gold Parts’ Aesthetics and Durability
Gold’s natural beauty can be elevated with trattamento superficiale to boost luster, durabilità, o funzionalità. Our services are tailored to gold’s unique properties:
- Lucidatura: Creates a mirror-like finish (surface roughness Ra <0.05µm) for luxury jewelry and decorative parts—our master polishers use diamond pastes to achieve unmatched luster.
- Placcatura: Adds thin layers of pure gold (24K) to gold alloy parts (per esempio., 18K) to enhance luster, or rhodium plating to white gold for a brighter, scratch-resistant finish.
- Coating: Applies clear protective coatings (per esempio., ceramic) to gold parts used in harsh environments (per esempio., assetto automobilistico, dispositivi medici) to prevent tarnishing and wear.
- Texturing: Adds intricate patterns (per esempio., brushed, hammered, engraved) to jewelry or art pieces—we use laser texturing for precise, repeatable designs.
- Finitura: Includes deburring (removing sharp edges) and ultrasonic cleaning to ensure gold parts are ready for use or sale.
Table: Impact of Surface Treatment on Gold Part Performance
| Treatment | Surface Roughness (Ra) | Luster (0–10 Scale) | Tarnish Resistance (Salt Spray Test) |
| As-Printed | 0.5–1μm | 5–6 | 72 ore (minor tarnish for 24K) |
| Polished | <0.05μm | 9–10 | 144 ore (minimal tarnish) |
| Rhodium-Plated (White Gold) | <0.05μm | 9–10 | 500+ ore (no tarnish) |
| Brushed Textured | 0.2–0.5μm | 7–8 | 200+ ore (no tarnish) |
Tolleranze: Precision You Can Trust
For gold parts—whether delicate jewelry or critical electronics—tolerances E precisione are non-negotiable. Our process ensures consistent, tight precision:
- Tolerance Levels:
- For jewelry and fine details: ±0.02mm (per esempio., to ensure gemstone settings fit perfectly).
- For electronics and medical parts: ±0,05 mm (per esempio., to ensure connectors make secure electrical contact).
- Dimensional Stability: We use heated enclosures and controlled cooling to minimize gold’s thermal expansion (coefficient: 19.3 μm/m·K), ensuring parts retain their shape post-printing.
- Measurement Techniques: We use calibrated tools like optical comparators (precisione: ±0.001mm) and CMMs to verify every dimension—ensuring compliance with quality assurance standard (per esempio., ISO 9001 for manufacturing, ISO 13485 for medical).
Per esempio, our 18K gold jewelry settings have a tolerance of ±0.01mm—guaranteeing that even small gemstones (1mm+) fit securely and align perfectly.
Vantaggi: Why Gold 3D Printing Outperforms Traditional Methods
Stampa 3D in oro offers a range of benefits that make it superior to traditional goldworking (per esempio., casting, handcrafting):
- Unmatched Customization: Create one-of-a-kind designs (per esempio., personalized jewelry with engravings, patient-specific dental crowns) without extra costs—traditional methods require expensive molds or manual labor for customization.
- Complexity Made Easy: Print intricate geometries (per esempio., hollow jewelry with internal patterns, lattice structures in electronics) that are impossible to handcraft or cast.
- Velocità: Prototypes are ready in 2–4 days (contro. 2–3 weeks for traditional casting), and production lead times are cut by 60%—ideal for time-sensitive projects (per esempio., holiday jewelry collections).
- Cost-Effectiveness: Reduce gold waste to <3% (contro. 20–30% in casting) and eliminate tooling costs—critical for high-value gold materials. For small batches (1–50 parts), 3D printing is 40–50% cheaper than traditional methods.
- Sustainability: Recycle 95% of unused gold powder, reducing environmental impact and lowering material costs—traditional casting generates non-recyclable gold scrap.
Innovazione: Merge gold’s luxury with functionality (per esempio., gold electronics connectors that are both conductive and aesthetic) to create new product categories.
