Challenges in processing of precious metals
Challenges in processing of precious metals
The jewelry industry is built on tradition, artistry, and precision. However, modern manufacturing challenges persist, particularly in the production of custom high-quality products and advanced alloys, especially in the form of metal powder. Conventional methods of material processing often limit design freedom, and increase waste. Additionally, the need for high-purity precious metal alloys based on customer requirements and sustainable production methods creates an increasing demand for innovative solutions.

01
Recycling Jewelry Waste
The jewelry industry generates significant metal waste during casting, machining, and polishing. Implementing advanced recycling techniques allows for the recovery and reuse of these materials without compromising their purity or mechanical properties. Innovative processes such as ultrasonic reatomization enable the transformation of out-of-spec or excess material back into usable powder, reducing material losses and improving cost efficiency.
02
Enhancing Gold Alloys for Durability
Traditional gold jewelry is prone to wear and deformation over time. By carefully alloying gold with elements such as titanium, palladium, or platinum, manufacturers can significantly improve its hardness, scratch resistance, and overall longevity. Controlled alloy development allows for the retention of gold’s aesthetic appeal while enhancing its mechanical properties, making it more suitable for everyday wear.
03
Anodized Niobium and Tantalum for Unique Jewelry Designs
Niobium and tantalum offer an exceptional ability to form stable, colored oxide layers through anodization. This process allows jewelers to create vibrant, corrosion-resistant surfaces without the need for dyes or coatings. By applying precise voltage control during anodization, a wide range of colors can be achieved, expanding creative possibilities in modern jewelry design.

Case Studies
Our case studies showcase how we’ve supported partners across industries with tailored solutions—from alloy development to process optimization. They focus on real challenges and how our technology helped turn ideas into results.
Universities and research institutes today face the challenge of quickly changing research directions and the need to adapt their equipment to new projects, often within tight budget constraints. AMAZEMET’s rePOWDER ultrasonic atomization system addresses this by providing an open platform designed for modular expansion. This allows institutions to start with a core system and expand their capabilities as research needs evolve and funding becomes available. The journey of the Technical University of Munich (TUM) with rePOWDER is a prime example of this principle, showing how upgradability supports innovation and protects the long-term value of research investments.
Since our foundation in 2019 as a dynamic spin-off from the prestigious Warsaw University of Technology, we at AMAZEMET have rapidly established ourselves as key innovators in the additive manufacturing (AM) and advanced materials sector. In just six dynamic years (as of May 16, 2025), we have demonstrated remarkable growth and technological prowess, driven by our mission to empower scientists and engineers worldwide with cutting-edge solutions for material development and processing.
