3D Printing Copper | Hackaday



Individuals actually need to 3D print steel, however whereas true steel printers exist, they nonetheless are costly and out of attain of most hackers. Nevertheless, even for those who can afford an unique printer or use metal-impregnated polymer, you don’t typically see copper as a print materials. Copper has excessive electrical and thermal conductivity which makes it very helpful. However that thermal conductivity additionally makes it very troublesome to print utilizing any course of that includes heating up the fabric and copper displays widespread lasers used within the 3D printing course of. Nevertheless, a German firm, Infinite Flex, is claiming a breakthrough that may enable printers that use a normal IR laser to provide copper components. The fabric, Infinite Powder CU 01 is appropriate for selective laser sintering and a number of other different laser-based methods.

The powder has 99.5% copper and particle sizes of between 10 and 45 microns. There are some copper alloys that cut back thermal conductivity to permit printing, however typically the explanation you need a copper half is for its thermal properties. A kilogram of the ability will set you again practically $100, so it isn’t dust low cost, nevertheless it isn’t astronomical, both.

You possibly can add copper wire to a print, in fact, however that’s not the identical factor. There are additionally strategies that work like electroplating, however they’re often fairly sluggish.

After all, to make the powder work you’ll need a metal 3D printer. We do know there are lots of methods to print copper.
