Can that thing print lower receivers?

Technically it can. Legally, we aren't registered as a firearm manufacturer with a federal firearm license, so we can't print that kind of thing for our patrons lest we incur the wrath of the ATF. And even if I were interested in trying that as an extracurricular activity after hours, I'd want something other than PLA.

I guess that would count as a transfer, even if there wasn't a sale. Lol, yeah I wouldn't want to pull the trigger on that. I've seen plenty of videos of printed guns being fired but I'm still not sure I'd be comfortable firing one myself.

On a vaguely related note, did you know that Wyoming has a law on the books prohibiting the feds from enforcing the NFA on firearms made and kept exclusively in the state? I wouldn't want to be the person that tested that law but it'd make for an interesting court case.

A few states have the same laws regarding suppressors and machine guns. Especially under the 2nd, 9th, and 10th amendments, it's entirely reasonable. But government enforcers are anything but reasonable.

A 3D-printed AR-type receiver is quite viable, provided there is some reinforcement at the buffer tube region. I'd also suggest a unitized trigger drop-in kit instead of the usual pinned separate components.

Yeah, the attempt to negate the entire act by doing an end run around the interstate commerce clause had me amused. I find it curious how federal enforcers largely give up if they don't have the cooperation of the state enforcers.

I've always stayed away from ARs just because I dislike the 5.56 round. May have to reconsider that, one running 6.5 creedmoor would be right nice. Hmm....

.300 Blackout is ideal if you want a suppressed SBR.

That would be fun. Don't know how much of a need I have for one though, feel like I'd get more/better use out of something with a little more zip and range.

I knew a guy who used .300 Whisper (the wildcat round later commercialized as .300 Blackout IIRC) as his whitetail round in the woods here in the Pacific Northwest. He had bursitis or something in his shoulder. It was a balance of power and recoil he could manage.

As for the other point, isn't it odd how a clause written to prevent states from taxing or otherwise obstructing interstate commerce has become a means for the federal government to control interstate commerce?

According to the 3D Print General on Odysee, PLA+ is a good material for 3D printing firearms. His latest is glass reinforced nylon, but that takes a heated bed and enclosure.

Well, the Dremel has a heated bed and an enclosure, but we're not using PLA+, much less more exotic filaments. Glass reinforced nylon is basically a FDM Glock-like material though. Plenty tough.
