Topic: prusa slicer creates seam that wont print

Ok, so i am trying to print this:

https://www.thingiverse.com/thing:35383

I am printing it vertical. In prusa slicer 2.0, when i try at any layer height, it creates these seams along the fuselage of the aircraft, on both sides. When it prints, the pieces are not connected, the print head just skips that half mm section. I have tried in S3d and its fine. But i want to get it to work in prusa slicer. thanks

FWIW: I always print in steps of 0.04mm. I have tried for this stl 0.2,0.24......0.36 and the seams still happen

Turn off seam position aligned and see if that makes a difference?

Re: prusa slicer creates seam that wont print

the problem is with the file itself, the walls are just too thin.
my old standby, Slic3r v1.2.9 has issues with it as well.. in fact, it is completely missing a section...

the only reason S3D is "working" for this model is because of the built in 'fudge factor' of the program. it was meant to deal with bad models like this in a relatively pleasing manner, as well as sort out other issues that the end user is either to lazy, or can't be bothered to learn how to correct properly.

No, I do not like the program. Nuff said about that.

Re: prusa slicer creates seam that wont print

Keep in mind that thingivers is simply a repository for 3d files.

It is not particularly curated . the files do not go through any quality checks
there is no requirement for functionality or printability.
Some of the more responsible contributors will make better quality  files and actually print them before loading.

Re: prusa slicer creates seam that wont print

Like Tin said, Thingiverse started as a place that 3D artist could share their works at. It was not till the last few years that 3d printing got popular and more mainstream that people started using it for files for 3d printing as well. The issue mainly is that many 3d artist have no idea what it takes to make an object printable and just think anything 3d can be printed.

Personally unless the artist has a printed sample or I see other makes posted of the item I will usually avoid it as the artist probably created it without knowing what was needed to make it work.

Re: prusa slicer creates seam that wont print

ok, so while at work, i messed with the file in prusa and s3d.. i have come to the conclusion that the modeler just used some bad practices when making this file.

I agree with what others have said about the file. Its just WAY TO THIN!!! i tried a test print in different orientations and the sections are way thin:/

thanks for taking a peek at this and getting back to me. I worked a 12 hour shift so i couldnt reply until now haha.

thanks again. Im still all about that prusa slicer though. its a nice package

Now i just need to find a good stl of the blackbird..that i dont have to pay money for haha

Or... you could attempt to "fix" the existing file by making the walls just a little thicker. there are free programs that you could do this with, such as Meshmixer or Blender.
My personal preference would be Blender, but I am pretty well versed in using it to modify stl files, lol

i could do that. i have Sketchup pro, which i have heard can do this, but i also have mesh mixer. the STl has alot of thin walls haha.

thingiverse does have a useful feature called "Makes". It shows a count of how many people have printed the model and their uploaded photo of their print. This is quite useful to see how printable the model is.

There is also "Remixes" which shows other models derived from this one. Sometimes some kind soul who had trouble printing the model has uploaded a fixed version of the model as a remix. Perhaps there is a remix of this model.
