I am very new to 3d and Bambu. I appologize for question in wrong spot… Cant figure out how to create a new topic/question… The short of it is… I have been given about 15 brand new spools of Ultimaker PLA filament, and am wondering if i can safely use those in an A1?
thank you very much
oh thank you so much for reply… ! 
I will have to change the default nozzle out ?
Am I correct in that ?
And probably have to run a “flow test”(I forget the correct term)?
You’re welcome. You won’t need to change out the default nozzle for the PLA. It comes with a .4 steel nozzle which will work great with PLA. There are different size nozzles and ones made out of harder materials, those will come along later in your 3D printing journey. You can definitely run a flow test but I would print some things using the “Generic PLA” setting in Bambu Studio first and see how the prints come out. Bambu printers are really good about not needing many calibrations. Put some of the Ultimaker in and print one of the models that are on the printer, see how it looks.
WOW
thanks so much!!!
I am just abt to order the A1…
At the library where I work we have 2 P1S’s and i am smitten with them only just getting them installed and put on the floor for patron usage…
To the point I want my own… I don’t think I i need a p1s… now…
They “gave” me 3 utlimakers to try to salvage at home…(1 works the other 2 are suspect)
And will try but I don’t want my exuberance to wain.
So I was thinking of getting an A1 and going to town especially since I have the access to the filament which they have decommissioned and will only use bambu in the p1s. Which is great for me now that I know I can use it especially to get my feet wet.
I was just worried that the size and brand would dork up the A1 not being bambu specific…
looks like now I have to place a black Friday order!!!
Just check to make sure the filament is 1.75mm diameter. Ultimaker used 3mm for a long time IIRC.
Thank you !
The specs on the box says 2.85mm 750g
so is that too large for the 4 nozzle?
That is too large for most consumer FDM printers. The usual diameter is 1.75mm.
OK well… now my 10 rolls are too big in diameter for the A1…?
Correct… But they will be good for the Ultimakers you have. That size of filament is getting harder and harder to get. You may be able to sell them via ebay etc.
When it says “Not recommended” means… i can still do it? What would be the implications of doing it?
Those filaments are “not recommend” because printing them greatly benefits from using an enclosed printer. The chamber temperature needs to be as high as you can get for them to print correctly.
Wow, I’m sorry, I assumed too much. I knew 2.85 filament existed but I’ve never seen it in real life. I didn’t mean to give you bad info.
Welcome to the forum! Like Jon said, the temperature is going to be a problem with those and even if you do put it in an enclosure they may or may not have used parts for the printer that can hold up to those temps.
