3D Printing Metal Materials
- Aluminum
- Steel
- Brass
- Copper
- Bronze

- Gold
- Platinum
- Titanium
If you’re a goldsmith, you can also order wax models for casting special metals.
Speaking of wax models, most 3D printed metals (including gold and silver) are actually produced through a process called lost wax casting. That is, not everything is 3D printed in factory. Services often turn to other companies that are specialized in metal production to finish the order. Nevertheless, the number of metal 3D printing services is growing rapidly all over the world. And at the same time, metal 3D printers are becoming more common at 3D printing services.
The reason big companies like metal 3D printing so much is that it can be used to build “topologically optimized” parts. This makes it possible to perfectly distribute the material in a component in order to make it thicker only where it needs to withstand more stresses, thus drastically reducing the weight without sacrificing structural integrity. However, this is not the only technology out there. Some are significantly more affordable and more accessible.
Please be aware that metal 3D printing requires special CAD designs. For general information, Shapeways offers metal 3D printing guidelines. For even more advanced information, take a look at this article from Statasys, which discusses metal 3D printers and the nuances of metal 3D printing.
