In short: Pure copper powder is used for parts that need the highest electrical and thermal conductivity. Because copper strongly reflects infrared laser light, it prints more efficiently on high-power IR or green/blue laser systems; induction coils and heat exchangers are typical applications.
Typical applications
- Induction coils
- Heat exchangers and cold plates
- Busbars and electrical connectors
- Rocket engine cooling channels (research)

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
Can copper powder be printed on any metal 3D printer?
Pure copper reflects 1064 nm laser light strongly, which makes it challenging on standard machines. High-power or green/blue laser systems give better results; share your machine and we will review compatibility.
Pure copper or CuCrZr?
Choose pure copper when maximum conductivity is required; choose CuCrZr when higher strength and hardness at temperature are needed together with conductivity.
Pure copper 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.
