SUMMARY
The discussion centers on the challenges of 3D printing with materials that have significantly different melting points, particularly metals and plastics. Metal 3D printing technology is already mature, as evidenced by applications in aerospace, such as SpaceX's 3D-printed rocket engine parts. The key issue is that high melting point metals can damage lower melting point materials during the printing process. A potential solution involves using metal in very small particle sizes, which allows for handling at high temperatures without compromising the integrity of adjacent materials.
