Crappy infill in Cura 3.0



  • Why do I have this crappy infill in Cura? I have not tried another slicer yet. I'm printing solid infill with 100mm/s with no problem so this tells me its not because my extruder can't push enough filament trough the nozzle. This infill was printed at 80mm/s. I've tried with 60mm/s and it's getting a bit better but still the problem persist. From what it can be seen it's like a stringing infill, thicker in one side and thinner in the direction where the nozzle is heading. And this repeats everytime the nozzle is hitting the infill lines. I have changed the infill profile but the result is the same. I don't see any options in Cura like setting the infill extrusion width. What can I do?

  • In the custom settings -> Quality you will find a setting called infill line width. I can assure you that your images do not show the normal quality of infill that Cura can produce. You have something badly wrong, there.



  • You are perfectly right. It was set to 0.4. I set it to 0.8 and everything is good now. But the problem is that I have to print the infill at 50mm/s. I can t still understand how can I print the solid infill at 120mm/s and the regular infill only at 50mm/s. If I go higher I'll get a nasty infill like in the pictures.



  • Try using "fast honeycomb" instead of rectilinear infill pattern, as the rectilinear pattern does not print directly onto the subsequent layer – this contributes to the problem you're seeing.



  • I don't know anything about your setup but maybe your extruder can't keep up. The product of line width * layer height * print speed must be below the max value that your extruder can hack. As for infill pattern type, I almost always use zigzag which is fast to print and adheres well to the walls.
