| Abstract Scope |
Copper is a soft, malleable, and ductile metal with very high thermal and electrical conductivity, which is widely used in industries such as aerospace, automotive, and electronics. However, the vast majority of additive copper is currently based on alloys of copper, not the pure metal. Pure copper has a high laser reflectance rate, over 90% with standard laser based AM systems making it difficult for the laser to continuously melt pure copper powder, which leads to interface failure and thermal cracking. Specific Laser Parameters were developed on the EOS M290 powder bed fusion (PBF) using single beads and density cubes to achieve a fully dense sample. With these parameters, the single beads and the density cubes were viewed using an optical microscope and scanning electron microscope (SEM) to verify that the copper is fully melting. |
