Ah, that explains why its radiation blocking is so much worse tham pure tungsten!

If you could manufacture Tungsten powder with spherical particles (rather than sharp pointed particles), I bet they could have far more tungsten in there and still have it 3d print effectively. Perhaps up to 50% by volume (95% by weight)
