Platinum Guild International (PGI) recently announced a groundbreaking achievement in fine jewelry with the launch of the Tùsaire Collection, the world’s first commercially available line of platinum jewelry created using direct metal 3D printing. Unveiled late last month, and designed by the renowned Scottish-American artist Maeve Gillies and produced in collaboration with ProGold in Italy, Tùsaire signifies a paradigm shift in how luxury jewelry is conceived, designed, and manufactured, leveraging the transformative power of additive manufacturing.
Overcoming the Challenges of 3D Printing Platinum
Platinum, prized for its rarity, durability, and lasting shine, has long presented significant challenges for additive manufacturing due to its exceptionally high melting point (around 1768°C or 3214°F) and inherent material properties, which make it notoriously difficult to work with using conventional methods. The Tùsaire project represents a major technical triumph, primarily utilizing Laser Powder Bed Fusion (LPBF), also known as Selective Laser Melting (SLM).
In the LPBF process, a high-powered laser selectively melts and fuses fine metallic powder particles layer by layer, based on a digital 3D model. Here’s a deeper look into its implementation for platinum:
- Process Mechanics: A thin layer of atomized platinum powder, typically 20-60 micrometers thick, is evenly spread across a heated build platform in a sealed, oxygen-free chamber (often filled with inert argon gas to prevent oxidation). A high-powered fiber laser (e.g., Ytterbium fiber laser) then precisely traces the cross-section of the jewelry design, melting and consolidating the powder particles into a solid layer. Once a layer is complete, the platform descends, and a new layer of powder is applied, with the process repeating until the entire piece is formed.
- Challenges & Solutions for Platinum:
- High Melting Point & Thermal Management: Platinum’s extreme melting point demands very high laser power and precise control of the laser’s interaction with the powder bed. Efficient thermal management within the build chamber is crucial to prevent internal stresses and warping in the printed part. ProGold’s expertise in precious metal alloys and PGI’s research were critical in optimizing these parameters.
- Material Sintering Behavior: Platinum’s unique metallurgical properties require careful calibration of laser speed, power, and spot size to ensure optimal densification of the material. Incomplete fusion can lead to porosity, affecting the jewelry’s strength and finish.
- Powder Characteristics: The quality, purity, and morphology (shape and size distribution) of the platinum powder are paramount. Spherical, uniform powder particles are preferred for consistent layer spreading and optimal laser absorption.
- Support Structures: Complex jewelry designs often feature overhangs and intricate geometries that require support structures during printing to maintain shape and prevent distortion. These supports must be robust enough for the build but also easily removable without damaging the finished piece.
- Post-Processing: After printing, the “green” part (the raw printed object) undergoes essential post-processing steps. This includes removing the support structures, heat treatment to relieve internal stresses and enhance material properties, and meticulous surface finishing (e.g., polishing, tumbling) to achieve the desired high-luster jewelry finish.
Unlocking Design Freedom and Customization
Additive manufacturing liberates jewelry designers from the constraints of traditional mold-based techniques. The Tùsaire Collection showcases the potential for complex and organic forms, lightweight hollow structures, and intricate interlocking elements that are virtually impossible to achieve with traditional casting. This technology allows for unparalleled geometric complexity, enabling designers like Maeve Gillies to translate mythical narratives into wearable art with unprecedented fidelity.
Furthermore, 3D printing enables unprecedented levels of customization. It allows for on-demand adjustments to sizing, integration of personalized design elements, and the creation of unique, bespoke pieces at scale, offering a new level of personalized luxury. The integration of anodized titanium accents, also facilitated by advanced manufacturing techniques, further enhances the design possibilities.
Sustainability at the Core of Luxury
Beyond design innovation, 3D printing of platinum offers significant sustainability advantages. The additive nature of the process minimizes material waste compared to subtractive methods like traditional casting, which can generate substantial scrap. Additionally, platinum’s inherent properties, including low reflectivity and excellent heat control, make it an energy-efficient material for laser-based manufacturing. The Tùsaire Collection embodies a future where luxury and environmental consciousness converge, setting a new standard for responsible production in high-end jewelry.
A Collaborative Milestone
The realization of the Tùsaire Collection was a testament to the collaborative spirit between PGI, ProGold, ORIGINALLUXURY, and other industry leaders. Their combined expertise in platinum, additive manufacturing, and luxury jewelry design has paved the way for this groundbreaking commercial launch.
“Additive manufacturing will be very important for the future of jewelry as it unlocks so many new possibilities,” stated Tim Schlick, CEO of PGI. Margot Stuart, co-founder of ORIGINALLUXURY, echoed this sentiment, emphasizing the pivotal role of cross-sector collaboration in redefining the future of platinum in modern luxury.
The Tùsaire Collection: A New Chapter for Platinum
The Tùsaire Collection marks a significant turning point for the jewelry industry, demonstrating the viability and transformative potential of 3D printing for precious metals. By moving beyond one-off experiments, this collection establishes a new precedent for how high-end jewelry can be imagined, manufactured, and personalized. As platinum becomes increasingly accessible due to current market dynamics, the Tùsaire Collection redefines luxury as an intersection of innovation, craftsmanship, storytelling, and sustainability.
