75% by weight sounds like a lot of tungsten...

But it is only 15% by volume... So to the casual observer, this material is mostly plastic.

But its more than 3 times as dense as PETG still. 1kg of PETG makes is 300+ meter of filament, while 1kg of this stuff is only 100 meter.

So I think the casual observer would notice that. But also means with thar price per KG.

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)
