3d printing materials with different melting points?

Click For Summary
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.

PREREQUISITES
  • Understanding of 3D printing technologies and materials
  • Knowledge of melting points of various materials, specifically metals and plastics
  • Familiarity with particle size effects in material properties
  • Experience with safety protocols in metalworking, including protective gear usage
NEXT STEPS
  • Research advanced techniques in metal 3D printing, focusing on particle size manipulation
  • Explore the properties of different 3D printing materials, particularly their melting points
  • Investigate safety measures for working with high-temperature materials in 3D printing
  • Study case studies of aerospace applications utilizing 3D-printed metal components
USEFUL FOR

Engineers, 3D printing enthusiasts, materials scientists, and professionals in aerospace manufacturing will benefit from this discussion, particularly those interested in the intersection of different material properties in 3D printing applications.

A 3d printer that could print metal and other materials would revolutionize everything. The only problem is that metals have a really high melting point, so if you try to get a metal hot enough to bind to the other metals in its vicinity it would probably destroy the bonds of the neighboring materials such as plastic that have a much lower melting point. How could this be solved?

And this photo, taken a few minutes ago, shows that I can hold white hot metal in the palm of my hand. The secret is that the white hot steel is in very small particles.

A few sparks can be seen flying off in various directions. That is why I ALWAYS wear google over my glasses and stand off to the side when grinding. This is my slow grinder, running slightly less than 2000 RPM. It's used for rough work.
