In short: 925 (sterling) silver is a jewellery alloy of 92.5 % silver, mostly balanced with copper. Metal 3D printing allows complex, customised jewellery designs to be produced directly without casting models.
Typical applications
- Custom rings, pendants and earrings
- Lattice and hollow lightweight jewellery
- Precision decorative parts

Particle size and compatible processes
The standard cut is 15–53 µm, suitable for laser powder bed fusion (LPBF / SLM / DMLS) machines. Coarser cuts for DED/LMD processes can be requested. Share your machine model and layer thickness and we will confirm the right cut and batch documents together.
Frequently asked questions
What is the advantage of 3D printing with silver powder for jewellery?
Lattice and hollow designs that cannot be cast can be printed directly without models or moulds, making one-offs and small series economical.
925 sterling silver powder price: what does it depend on?
The price depends on order quantity (kg), particle size cut, packaging (argon-filled cans or bottles), required documents (certificate of analysis, PSD report) and lead time. For a current price, state the quantity and your machine model in the quote form.
Which documents come with the order?
A certificate of analysis with chemical composition, particle size distribution (D10/D50/D90), flow and density values can be requested for each batch. Additional documents for aerospace, medical or dental projects are confirmed at the quotation stage.
