Gold filament revolution: using precious metal 3D printing to change design
Imagine creating intricate jewelry, precision dental implants, or custom luxury components entirely within real gold— No need for traditional molds, engraving tools or weeks of labor. this is power Gold wire 3D printinga frontier where centuries-old metallurgy meets digital innovation. For designers, engineers and manufacturers around the world, this evolution unleashes unparalleled creative freedom, precision and speed.
The science behind gold filament 3D printing
Gold silk printing is completely different from traditional plastic 3D technology. Two advanced methods dominate:
-
gold powder bed fusion
- use Selective Laser Melting (SLM) or Direct Metal Laser Sintering (DMLS)a high-power laser selectively melts microlayers of 24K or 18K gold powder.
- result: Fully dense, 99.9% pure gold Parts with excellent mechanical properties. No binders or fillers – pure precious metal.
- Metal filled polymer filament
- Polymer filaments are infused with fine gold particles (usually PLA/PHA + 10-20% gold powder).
- Post-processing conversion output: Objects are chemically treated or electroplated to achieve true metallicity.
For industries with higher accuracy requirements, such as aerospace or medical equipment, SLM/DMLS dominates. Its ability to produce functional end-use components sets it apart from aesthetically focused filament solutions.
Why this is revolutionary
- Unfettered creativity: Complex geometric shapes – microlattices, hollow structures, organic curves – are created in hours, bypassing wax molds and hand carving.
- speed: From CAD file to finished golden object Less than 72 hours.
- Zero waste production: SLM printers recycle over 95% of excess gold powder, minimizing environmental impact and material costs.
- medical breakthrough: Biocompatible gold implants protect dentures, surgical tools and hearing aids from corrosion.

FAQ: Gold filament 3D printing
Q1: Yes "gold wire" Real pure gold?
Gold filaments vary:
- SLM printing: Use pure gold powder – yield 99.9% pure gold.
- composite filament: Typically plastic polymer + gold particles (~15%), requiring plating to obtain a metallic finish.
Q2: Can gold printed parts replace traditionally made jewelry?
Absolutely. SLM-generated gold surpasses cast items in detail resolution, geometric freedom, and durability. It has been adopted as a signature collection by Cartier, Omega and independent craftsmen.
Q3: Which industries benefit the most? Top use case?
- jewelry: Custom pendant, heirloom quality setting.
- Dentistry: Biocompatible dental crowns/bridges.
- aerospace: Gold-plated heat shield.
- electronic products: Corrosion-resistant connector.

Q4: How does GreatLight ensure the safety of final products for medical/dental use?
ISO 13485-certified SLM protocols and post-print CT scans ensure structural integrity, biocompatibility per ASTM F2885, and 100% traceability of material sourcing.
Q5: Can I print with rose gold/white gold alloy?
Yes. We design custom gold alloys via parameter-tuned SLM (e.g. 18K Rose Gold = 75% Au + Copper/Silver), ideal for color-sensitive luxury goods.
Q6: What is the expectation of turning losses into profits? Cost basis?
prototype: 48–72 hours Includes machining/polishing. Volumetric scaling significantly reduces unit costs compared to traditional benchtop work.
