Is it possible to build this at home using a 3d printer ?

It appears that that's exactly how they made it.

What you end up with, though, is a pretty specific muffler.

Making a wall out of these blocks will take a while, and it'll only block a narrow range of frequencies, somewhat.

But hey, it's better than plywood because you can, like, stick your hand through it! And it's hi-tech!

Sign me up! I’d love to muffle my GPU miners. They need air and make plenty of fan noise.
