We have high quality copper powders for a variety of 3D printing processes such as L-PBF, DED, binder jetting, DLP and cold spray. 1)CuCr alloys for L-PBF  -Copper is challenging to be fully densified via additive manufacturing due to its high reflectivity of IR laser and high thermal conductivity. We have the two copper alloy grades for L-PBF with great performance of 3D printed parts by achieving full densification with the IR laser output of 400W. -CuCr shows the highest conductivity alloy, 95 IACS% as electrical and 377W/mk as thermal conductivity. - CuCr is easy-printable and shows small resolution because its stable meltpool. You can achieve less than 150um with standerd laser output such as EOS M290, which is appropriate for thermal management applications including cold plate because higher surface brings about higher thermal efficiency. We can offer these parameters with such as EOS M290, Concept laser M2 and SLM 280 to customers for free, which can reduce parameter development cost. 2) High Purity Copper powder  -Over 99.9% high purity copper powder with low O2 amount   -it can be applied for L-PBF, binder jetting, EB and cold spray
