3D printing of amorphous materials without destroying the amorphous structure may be possible without “killing the goose” but we still have the issue with sintering. if sintering is necessary, it comes with the inevitable 10-15% shrinkage which destroys one of the main advantages of BMG…..zero shrinkage.

This problem forces the 3D process be such that sintering is unnecessary.

New point….mismatching the atomic radii of the alloy components has a chemical term…..they are sterically hindered in that the mix of sizes block the individual atoms from forming bonds.
