[Is there a way to get Cura to skip infil altogether in areas that are too small?]

Hi Greg, thanks for prompt reply. I was considering Support Blocker, but that would be a lot of work to overlap all those tiny segments. With Cylindrical Support plugin it should be much quicker though, but not perfect. I'm still on 4.11, so I can I'll give it a try, and play with Infill Layer Thickness, as I've never used it before. 

It would be great that existing 'Minimum Infill Area' could be enhanced with option to indicate fill %.

Hi,

Resuming this topic, as I've got similar request. I'd like cura to NOT print infill in small areas, as it doesn't add any structural strength to the print but instead extends print time. It seems there's just 'Minimum Infill Area' that could do the trick, but it prints solid infill, or to be precise, skin. Attached my model with sliced with 0 and 40 mm2 value. Is there a way to keep that narrow spaces infill free?

I've been updating Cura for a while and I've never seen the connected infill lines, so it must have been enabled by default just in some more recent version.

Yes, that's what I was looking for. Thanks!

 

This should be enabled by default. The additional material cost is minimal but the quality improves, not only of infill but also of inner and even outer walls. Additionally the noise is significantly reduced.

I think the reason for bad infill quality (strings, blobs, gaps near inner wall, etc) is that it's composed of separate lines touching inner walls, meaning that when nozzle reaches a wall the extrusion is paused, nozzle moves to another place and extrusion is resumed.

During the movement the plastic ooze out and makes a mess. It could possibly be improved a bit by increasing the overlap.

 

For example Simplify3D has a different approach - infill is in a form of continuous single extrusion line whenever possible. It makes infill very strong, nicely fused with inner walls. It actually can work as an additional inner wall, reducing need for regular wall.

Is it possible to have a continuous infill line in Cura?
