I have downloaded a litophane from bambulab so I printed frame on X1C. And I use what is recommended for printing this, filament is generic PLA+. But I get really bad print of it. Can anyone tell me why?

Hey there,
Could you be a bit more specific on what filament and printer you are using? And could you send the 3D file so I can take a look at it?
You are showing the holder/frame? What filament are you using?
The second pic looks like a shift or movement in the print?
filament is generic PLA+, printer is X1C
here is a frame
https://wiki.bambulab.com/knowledge-sharing/cmyk-color-lithophane/cmyk_frame_x1c_v2.3mf
and here are instructions?

And can anyone tell me how to create portrait lithopane
yes it is a frame for lithopane, downloaded from bambulab. Filament is generic PLA+
I don’t have the expertise on the printing issue to really help with that. I would make sure PLA is dry, do a calabration, print a small known object to see if it shows any problems and look at nozzle to see if any clumps are on it. Basic things.
On printing Lithophanes. if you do CMYK ones print them lying down flat. And on the one color ones you may need to print them flat if they are thin as they can droop over.
For sparse infill I use rectilinear at 100%. When I went with the default of gyroid at 15% I would get shadow banding across the print. The print had it’s own small edge frame.
2 Youtube videos I like are below. They have some good general info and I generally use the slicer settings from the cmyk one, even for single color, just ignore the multiple stl files and color filament setting part.
I have done several one color (white) lithophanes but only tried CMYK once so far. I can see that I will need to do a lot of testing on that to get something I like printed and I have been to busy (lazy) to do that.

Edit:
Going back and looking at the instructions you included I see that they are pretty much the same as ones in videos I linked. Sorry about that but maybe they will help. I use desktop software to make mine so I had just glanced at the wiki part before.
Also, you might try downloading the STL file for the frame rather than the 3mf. but you will need to double check settings.

the problem is in this frame printing there are overhangs and some break at the behind
which slicer and what version are you using? Are you on windows, mac or linux?
When I open that 3mf file in Bambu studio it auto adds a tree support for the top overhang. Is it not adding it for you? Or is it still having that issue with the tree support?
This is from Orca slicer, which auto adds another support. Niether of these is the latest version of that slicer.
yes it adds tree support but only inside of the frame but not on de edge where you see overhangs
today I start to print with normal support to see difference.
I use bambulab studio for slicer and it is the latest and I am on windows 10
I used this frame for mine.

So I did some testing. The 1.x version does seem to add an extra row of support. This is the same 3mf file opened in 3 different BS versions. No tweaks or setting changes. Maybe the threshold for generating them was tweaked in the 2.x versions or maybe some factor outside of BS caused by my PC. Don’t know. I am also windows 10
1.10.1.50
2.00.01.50
2.00.03.54
that was the problem because there was no second row of support.
I tried again with tree support and didnt add second row so I used now normal support.
I hope you are able to get a good print now. Wierd that the 2.x version wouldn’t support the outside overhang.
yes it is strange for me too.
I will see later when I am going to pick up print
Just an FYI, I did some testing and clearing the “Remove Small Overhangs” checkbox in the “Support” section will add tree support to the outer overhang. It also will add a support tree on the back side but I don’t see that as a bad thing.

thank you for the tip.
I printed with normal support and it came out super. But will try this also to print another one with tree support
