Laser-melted metal 3D printing technology has the advantages of forming complex structural parts, high material utilization rate, and no need for molds. The 3d brass printing technology has great application potential in the preparation of copper alloy heat exchangers, exhaust nozzles and other parts with complex structures. However, due to the excellent thermal conductivity and reflectivity of copper, the absorption rate of copper metal in the laser melting process is low, and it is difficult for the laser to continuously melt the copper metal powder, resulting in low forming efficiency and difficult control of metallurgical quality in the process of brass 3d printing service.
Copper based alloy 3D printing materials and new 3D printing lasers are promoting the development of copper 3D printing technology. SLM Solutions, a metal 3D printing company, has validated a copper alloy CuNi2SiCr for selective laser melting 3D printing and established the ideal printing parameters for this material
The copper alloy CuNi2SiCr material is compatible with all laser-melting 3D printing systems from SLM Solutions and is a heat-hardened alloy characterized by high stiffness and a balanced combination of electrical and thermal conductivity. The alloy consists of nickel and silicon and has high corrosion resistance and wear resistance.
SLM Solutions identified and validated the CuNi2SiCr copper alloy and established the ideal printing parameters for the material. When testing these parameters, the main issue highlighted by the copper alloy was its sensitivity to oxygen, and to address this, SLM Solutions recommends a maximum oxygen content of 500 PPM in its system when using the material.

3D-printed copper alloys typically have lower electrical conductivity than pure copper (with an IACS value of 100%). SLM Solutions' CuNi2SiCr material increased its IACS value from 14% at printing completion to 40% after heat treatment. Although less conductive than pure copper, it is still suitable for some conductive applications.
According to SLM Solutions, the electrical conductivity of copper alloys decreases as the number of alloying elements increases, but other properties such as strength can be improved, with CuNi2SiCr superior to pure copper. The performance of CuNi2SiCr 3D-printed parts can be improved by implementing heat treatment processes, such as precipitation strengthening to make parts have higher strength and conductivity.
CuNi2SiCr copper alloy 3D printing material is suitable for application in mold manufacturing, electrical engineering conductive contact, welding nozzle, valve and other fields. The strength, resistance and conductivity of CuNi2SiCr materials make it ideal for manufacturing conductive parts in mechanical, thermal and tribological stress environments.
Compared with traditional manufacturing process, 3 d printing CuNi2SiCr material and metal in combination of advantages of degrees of freedom of design to be able to unlock new application of the more traditional process cannot be achieved, including design and manufacturing with complex internal geometry and topology optimization of copper alloy parts, finally be lightweight, more cost-effective components.
