"might stop anyone from 3D printing guns"
I can guarantee you that it won't even do that.
It absolutely won't do that. You know how many millions of early generation Prusa and Ender 3 printers are in the US? Many of these models have no internet connectivity whatsoever and print from SD card.
What that means is they will also try to incorporate spyware into your CAD and/or slicer software, which is even more invasive.
This is a anti-privacy bill.
It won’t stop anyone buying or importing innocuous machinery parts like 2020 aluminium extrusions or GT2 belts either. There are mature generic 3D printer designs out there that outperforms RepRap i3 bedslingers.
E.g. https://vorondesign.com/voron2.4
I don't even understand how they imagine this will work. Most printers are certainly not powerful enough to do real 3d object detection. Even if they forced slicers to include this, just fork OrcaSlicer and take it back out. Actually a lot of printers run open source software as well, so we can just fork klipper of it ever comes to that.
It absolutely will not stop some people. But those are not the ones committing gun crimes
It's like making a normal printer that's mandated by the government to never print dicks
I mean normal printers will not let you print money. That's what gave these idiots the idea to begin with I'd wager. But there are orders of magnitude in difference in difficulty between making a piece of software capable of autonomously recognizing a few existing designs of dollar bills and one that can tell a working gun part that can take a shape that can vary almost infinitely from other objects that can also take nearly infinite shapes.
They don't recognize bills. They recognize a pattern of tiny yellow rings in the bills, the Eurion constellation, which can barely be seen by the eye. This supposedly will stop copiers and printers from scanning or printing any document that has these.
Bypassing these is trivial.
