3D printing with 100% pure Copper

3D-print parts with RS copper, an alloy containing 99% copper or 100% pure and unalloyed copper.

About pure Copper

A newly developed 3D printing process has made it possible to print with alloy containing  99% copper or even 100% pure unalloyed copper. Copper has always been a popular material for its great thermal and electrical conductivity. The pure copper alloy has an electrical conductivity of 100% IACS and a density of 8.9 g/cm³. Attaining a quality and efficiency higher then achieved by conventional alloys processed in 3D printing since reduced copper content also means lower conductivity.

 Common applications for 100% copper parts are inductors and heat exchangers.


✦ Great thermal properties

✦ Excellent electrical conductivity (100% IACS)

✦ Design freedom for 3D printing in Copper increases the performance of parts

✦ Bacteria will not grow on it

✦ Highly malleable


✧ Sensitivity to oxidation leads to a greenish shade

✧ Corrosion can occur at any moment

common applications for 100% copper

– Heat exchangers

– Inductors
