Structural strength on small things, test.

Hello fellow Prusa fans, I tested my 3D print on both Ender 3 and Prusa Mini and when sliced with PrusaSlicer then structure is much weaker than with Cura.

Here is my issue and now i tested results in reality on 2 different 3d printers. I still cannot figure out is it my fault or algorithms are so different. Test STL files for compare, slice and print included.

I have had similar experiences with the Mini.  Not so much with the MK3S.  Then again, the supports are impossible to remove from the Prusaslicr.

Did you use the same infill type on both the Cura and PS prints?

Yes but this is not about infill type but about analysis of of quality and how PrusaSlicer handles it. I am far from expert and everyone can test and make same quality slice with PrusaSlicer. Maybe those issues could find solution if PrusaSlicer would made CuraEngine library as optional slicing  backend? dont know if possible.

Out of pure interest i would really like to see if someone can make same exact slice with PS like it is on Cura slices, especially on small things. This proves that it is my own fault and i missed some option combination to get perfect physical structure slice. I really want to use only PrusaSlicer in future as it is so much faster and i prefer PrusaSlicer UI too.

RE: Structural strength on small things, test.

The reason I brought up infill was an observation a while back that when doing small parts, those just large enough to call for some infill, often have weak spots where the pieces of that infill are just not there.  They tend to snap very easily.
