They officially supported me printing without an Internet connection, which is stopping now.

Where do you see that? Seems one can still print via SD cards without any issue.

It says:

Operations That Do Not Require Authorization The following actions will remain unaffected by the authorization mechanism:

Sending status information from the printer (e.g., MQTT status push for tools like HomeAssistant).

Starting a print job using SD cards.

General operations outside the listed authorization controls.

You could still print without an internet connection, even before Bambu’s backpedaling.

My toilet doesn't officially support crapping without an internet connection either. I'd argue that in both cases it's implicit unless very explicitly disclaimed.

Why does a 3d printer need internet?

They specifically advertise connectivity for a mobile app.

My Oral B toothbrush advertises connectivity for a mobile app. That doesn’t mean they can arbitrarily impose an internet access requirement.

The way things are going though, I wouldn't be surprised if they did.

I mean, as a snarky hyperbole about how ridiculous consumer products have become, sure. In reality, I would be very surprised if Oral B decided I needed Internet access to use my toothbrush.

Worst user experience ever idk why but I miss being able to plug a cable from a printer to a device and then printing

Had the new requires phone app workflow and it was so buggy had to just resort to UPS/Fedex

It wouldn't, but, if the vendor somehow made it require one, despite the very impressive technical feat, I'd feel cheated. Robbed, even.

Yes, "lan mode" is an officially supported advertised feature, where you can happily print on an isolated network. (though as of this morning it now sounds like they're backing off after public backlash)

Interesting, this somewhat implies that outside of this "land mode" an Internet connection is otherwise required for printing

Yes, the default workflow on the product is that all prints go via their cloud service. For the first year or two of the X1C's existence this was the only way to print, but they later introduced lan mode.

Leading to obvious speculation as to why they have stuck themselves processing megabyte g-code streams between your desktop and the printer on the same network...

But since cloud use is optional anyone with the security/reliability/longevity concerns just don't have to use it.

Personally I don't see the cloud stuff as providing any value at all though I know people whose kids print stuff from their makerworld site via their phone app that consider it useful.

I have absolutely no insight into their operations or requirements, but when I see someone forcing traffic to their servers, I immediately think they’re looking for metadata, or training NN models on your data. NN generating 3D models is pretty valuable at the moment, and taking users data to train models without informing them is for some inexplicable reason considered ok even by many people that get foaming-at-the-mouth-mad over other privacy violations. Like I said, I’m just spitballing and have no knowledge of this operation, but it would give me pause before using it as a professional 3D artist.

Well yeah if you're not using LAN you're using WAN which means internet. But the option is there to use either one if you want, or even just put a physical SD card into the printer directly if you want, no network needed at all then, LAN or WAN.
