I've been interested in getting a 3d printer for a while now but am not deep into what's out there, does the ender 3 pro require any cloud or services that I can't run locally to function?
Edit: same question for the snapmaker U1.
Also, where do you source your fillament from? Any other ongoing maintenance requirements (material-wise)?
I want a 3d printer, not some new relationship with a corporation.
I mean anyprinter can be offline even Bambus. Mine run in LAN mode and are blocked by the router so no internet access. iOS has a really nice handy replacement that works in LAN mode also. I'm not saying buy their printer just that every printer can work offline.
Ender 3 Pro is a completely offline printer. It has a microSD slot and a USB port, that's it. No network connectivoty at all. It runs Marlin firmware which is a long-standing Arduino-based open source 3D printer firmware. It's highly customizable and upgradable. I added a CR Touch bed probe to mine and rebuilt the firmware to enable the unified bed leveling features. It's not the most user friendly but it's a decent, cheap platform, fully open source, and puts out decent prints.
You can also run klipper on them if you want network connectivity. Granted you need a raspberry pi to run klipper so there is that.
After running klipper on my Ratrigs I can't even consider Marlin anymore. Modifying a config file and restarting is less painful than having to compile and flash a bin for every modification or update.
As another 3d printing noob, why would I want my 3d printer connected and be in the mercy of some company? Feels like this dependency makes it so you don't truly own the product.
LAN mode. I kind of understand why they do it because it just works. I gave my Sister my X1C and it was the first printer I felt comfortable with giving her family, because it just works.
Klipper wouldn't do that at all on its own. It basically just uses an external computer to run the printer, rather than purely using the printers microcontroller. So you can connect to the computer remotely/over wifi and control the printer if you set it up to do so. It also makes it easier to add extra stuff like cameras, heaters, power switches, etc. too since it all runs through that computer and knows what the printer is doing.
That's what I switched to about 2 months after getting my Ender 3 S1 Pro. Klipper running from a RPi, lets me push sliced files out over WiFi to the printer right from Orca. So much better than dealing with SD cards.
I’ve come from an ender 3 pro to a Bambu P1S with AMS. As others have said the Bambu environment makes it “apple-like” (for better or for worse) to print. Set up, to print is maybe an hour? You spend the majority of your time with the printer actually printing. Which is why everyone (I included) are so upset about how Bambu is handling this.
Meanwhile the ender you spend the majority of your time getting the printer settings right, adding mods, adding firmware, trying new slicers, bed leveling, etc. I spent so much more time tinkering with my ender than printing that i just gave up printing altogether.
If you want to just print things it’s really hard to beat a Bambu. If you want to tinker and actually learn what 3d printing does and how it works, other printers like an Ender is the way to go.
I bought a Creality K1 before I received my P1S as a gift and the setup was pretty easy.
Other printers are there or getting there in ease of use, but Bambu Lab clearly had a headstart and used that to try and close their ecosystem
Thank you, this is very helpful information, too. Lucky for me, I like to reinvent the wheel from time to time for fun, so the more open option isn't scary, though it does sound like there's a decent chance my 3d printer will just be a dust collector what with all the other wheels I started reinventing but never finished. But I think I will add another hobby to the collection.
I don't know much about the Snapmaker U1 other than what's stated on this thread and on their site. Just looks like a more open alternative to Bambu if you need fancy features like multi filament printing.
I buy most of my filament from Micro Center (their Inland brand) and some I've gotten from Amazon.
Thanks for the quick replies! That snapmaker U1 looks great, but I do see that page referencing their app, so it could go either way, depending on whether their app is a mandatory part of the pathway.
The other one sounds like it might be a great way to get my daughter into more techy stuff, since she loves 3d printed stuff, so modifying it and needing to also modify the firmware might even be a plus for that.
It looks like you can control it with vanilla Orcaslicer. See the last post in this Snapmaker forum thread, for instance. It may or may not be willing to take gcode through the USB port—the specs indicate it has one.
It looks to me like they're continuing in their usual direction of fairly open software on mostly proprietary hardware.
I own a U1 and I use it completely offline from the internet. I upload files to it from OrcaSlicer or use the USB port. I can even use the smart phone app on my local wifi network.
I went with the Qidi Q1 Pro and I've been very happy with it. Orca Slicer's built in profiles for it have worked great so I didn't have to tinker. It runs Fluidd so once it was connected to the local network I could monitor and control it that way (and it will display directly in Orca Slicer).
There is a setting in the printer's interface to restrict it to local network only (and just to be absolutely certain I blocked it in my firewall as well). There are no penalties for not connecting it to the internet.
