Lead shielding is usually applied in sheets; and due to its low melting point, it can also be cast as a layer on other machined parts on applications where sheets are more difficult to use.

so machine a die, machine your part, build random fixtures, cast lead on to your part...

or just print it?

It's a bit of a no brainer.

Even if you just want a shielding layer, the convenience of this will win out on low volume parts.
