Clearly this is mostly security theatre (see eg comment about proving that them printer can't print a printer that can print a gun).

On the other hand - it would be low hanging fruit to prevent off the shelf printers to print well known gun parts? Much like photocopiers and scanners and printers won't scan, copy or print known currency bills?

Currency explicitly embeds detectable patterns to make software detection easy - firearm 3D models don't have any such feature.
