It is a great price for a higher quality filament, but it is a 3kg roll while most you buy are going to be 1kg rolls. These are significant bigger and obviously heavier, and generally won't fit on a standard filament roller that comes with the printer. So you would want a different roller system to sit it on (generally 3d printed).

Feel free to msg me if you want to chat more about specifics so we don't clog the thread.

Good luck and happy printing!

On an x1, that's about a 10 day print with 18kg of filament.

Most double 1kg spool dryers will fit a single 3kg spool

I want to print a shelving system and planned to use petg... Would PLA + be strong enough for that maybe? Would mostly be to display 3D prints lol, so wouldn't be real heavy load but more worried about long term as far as drooping and such.

I am not an expert. What I have read is that PLA creeps under weight over time and permanently shifts. PETG does not, but PETG is more flexible, so it will sag under weight. PLA-CF might reduce or eliminate the creep as it is stiffer. PETG-CF might be the best choice.

For any serious shelving, though, I'd just make it out of/buy it in wood or metal. Home 3D printing isn't really for large infrastructure type things, in my opinion.

I'm brand new to 3D printing. I plan on purchasing one for my wife. This is a good price. Should I get these spools ahead of time while I continue to look for a good deal on a 3D printer?

You will need some 1kg spools that are empty and use something like the "pastamatic" 3D-printed spool winder to transfer filament to them. I would try to grab a deal on a multi-color 10kg kit that includes 10 1kg spools that are full so that you get a running start and eventually can acquire filament in the bulk 2, 3, etc. kg spools and transfer them over. Depending on the 3D printer, many of your initial prints are going to be tools and/or accessories that help optimize your rig and keep your filament dry. There will likely be several days and multiple kgs of printing everything from desicant holders to risers that make everything work better. I finally got Kingroon PETG filament from an Alibaba deal dialed-in after downloading the profiles into Bambu Studio and running a calibration on my Bambu P2S. There is a lot of really good suggestions from advanced users that typically accompany the deals so you may want to run a search on Slickdeals for "filament". That said, I just returned a ton of SUNLU PLA+ 2.0 that I got from Amazon. I literally could not get it dialed in and kept having a lot of inconsistent results. YMMV and there will be lots of differing opinion on the reliability and consistency of these imported filaments of course.

Then you haven't seen the massive builds yet? I've printed several models and it is all dependant on the design. The last one I made is super sturdy in all directions especially under load and it's made from PLA. There's always a trade off depending on the material including metal, wood, plastic
