i’m a begginer in 3d modeling, and my first desingn looks ok in sketchup, but when i export it to stl exension and try to print it, the mesh has some problems, but i don’t know what i’m doing wrong.
You can see picture of the model in cura, sketchup web and meshmixer
.
Giving us the model to look at is more useful than just images.
As @Box wrote, its only a guess without a model to inspect, but from the red areas accented by cura I suspect there are interior faces where the parts meet.

I’ve uploaded the stl file
it looks like that is the problem, i didn’t know that i could’t keep interior faces…
Thanks a lot!!!
Please upload the .skp file instead.
Those interior faces make it look to the slicer like you have 8 pieces with an infinitely thin membrane separating the pairs. That’s neither a SketchUp solid nor something that can be 3D printed.
Is you plan to slice this with Cura and then print it with a FDM printer?
I opened your .stl file in Cura and sliced it without any problem.
And I see nothing that would prevent this from printing … so not sure what you mean by having “mesh” problems. Indeed … on the settings I used … Cura saw NO interior faces.
But, to be sure, this geometry will be impossible to print without using supports.
Here is a screenshot of the same .stl file, sliced with supports enabled.
Also, not sure what you mean by “export” to “stl extension.”
For me the typical workflow consists of:
-
Design in SketchUp … save design as .skp file.
-
While in SketchUp … use the “File/Export/3D Model” facility to save a .stl file of the design.
-
Open the .stl model in Cura … select the printer, the material … and then select/set the other various settings as appropriate/required.
Cura 4.4.1 has the 13 groups of settings … each with a dozen (or more) settings … so getting everything set up properly is no mean feat.
