Does this stuff have any use in 3D gun making?

It's really cool stuff that will expand the value of 3D printing immensely but since we are a board of gunthusiasts I ask the obvious question.

You can make voids and unsupported parts easier.

3D printing was already better at this,  but there were shapes that required some minimal supports or struts be printed to hold things up until the print was done, then you trimmed or sanded them away.  

Now, assuming it's a "color" printer that can switch on the fly,   one of the melting plastic filaments is water soluble and you just wash it off when done.

Some of the multi part plastic semi-disposable printed guns,  you could now print them in one piece,  and just wash it to free up the moving parts.

Spit balling.

What about  the 80% lower game? Print a solid chunk of plastic that is not a reciever. Sell it over net. End user washes out the voids, and installs the parts. Takes one more needed bit of knowledge away from "manufacturing".

Pretty sure this is what got EP Armory (and Ares Armor) in trouble with the ATF.  The Polymer lower was made of two different (and two differently colored) plastics.  Get rid of the white plastic, and all that's left is now "gun".  ATF claimed that wasn't a true 80% lower and got all asswipey about it.

Comparing the batfe to asswipes seems like an apt analogy, except that asswipes actually have a useful purpose.
