Ultrapure metallic powders with a guaranteed title and extra-fine and homogenous particle size, specifically developed for additive manufacturing processes (3d print) for the goldsmith sectors.

Powders belonging to POWMET are: precious powders at title of gold alloy and silver alloy; non-precious powders of bronze and steel.


POWMET line powders are atomized via an exclusive process which allows to obtain perfectly spherical particles with uniform chemical composition and low impurities content. They are sieved to obtain a precise granulometric distribution suitable to maximize the material performance during the production process.


Thanks to investments in large-scale machineries and a proven expertise in metallurgy and in the production processes, LEGOR GROUP is able to cope with any requirements, guaranteeing constant quality in both small and large quantities.

Using POWMET powders for additive manufacturing processes guarantees quality standards comparable to those obtained by using LEGOR GROUP’s MASTER ALLOY products for the traditional production technics, such as microfusion and mechanical work.

Choosing POWMET for additive manufacturing means:

  • more freedom in the product design and customizations
  • time-to-market reduction
  • easier prototyping stage
  • easier process in case of small quantities/batches production


Manufacturing jewelry pieces with PLM technology compared to the traditional lost-wax-casting is substantially different. Many advantages arise from reproducing jewelry designs directly from the CAD/CAM virtual image to the real metal piece. Read a brief analysis of advantages that both designers and manufacturers can benefit from when utilizing the new cutting-edge PLM technology:

legor group pearl of wisdom

Our “Pearl of Wisdom”

This year the Santa Fe Symposium reached its 30th edition, and to celebrate Eddie Bell, its founder, companies worldwide created several “Pearls of Wisdom”, little precious iconic jewels, as a gift. Our “Pearl”, made in association with Studio Poliero, consists of a 3D printed silver globe, with moving parts directly assembled during the printing process. […]
