There should be more out there and I just know I forgot a bunch. Generally however anything that comes in a fine powder can be 3D printed using the Zcorp process, anything that performs like a granular thermoplastic can be made with SLS, many metal powders can be made with DMLS and anything that performs like an ABS filament can be made with FDM. It won't necessarily work well and it might not look like anything and screw up your machine but by and large it will work. 3d printing service anand ahmedabad vadodara surat rajkot gujarat
If you look at Zcorp for example its just a question of using glue to stick powder together. So give a Zcorp machine any fine powder and it will to some degree work. I'm glad you asked this question because I think it is crucial for understanding the potential of this technology. As the industry grows more and more people will realize that their materials research produces materials that can be used for 3D printing. These new materials could be tested easily and then quickly introduced to the market including the installed base of 3D printers.
The fact that 3D printing reduces manufacturing to one two factor process: a material and a machine means that the ecosystem that is created by the technology is readily accessible by anyone. Just by a printer, feed lots of materials into it and eventually one will work. And when it does you can sell it to anyone with that printer. So, I would anticipate many more 3D printing materials in the future.
