Specific Area at Different Infill


Recommended Posts

Posted · Specific Area at Different Infill

I've been working on a few projects for work, and one of the designs I did, has a weak point that can't really be fixed by changing it. It's got specific dimensions.

 

Is it possible to make a specific area of a print at a different infill? Say you're printing the letter "A", and the bridge between the left and the right side need to be reinforced. Would it be possible to step from 50% infill to say 75% infill in just that area? Even gradually increase it?

If this isn't possible, could we make this a reality? There's probably more than just me who would benefit from this. I'm trying to get a Fabrication Shop setup at my work, and having some flexibility with software would be mint.

    Yes!  This feature already exists in cura.  There's many ways to implement this - all quite similar.  So this video explains it pretty well but... the GUI has changed a little bit.  It's still pretty similar so I think you can easily figure out how to do the same thing with the latest version of Cura:

    There are other tricks. If you want to increase infill density in your model you can put holes through your model - but holes so small that they will hold no air.  Cura will put "wall" lines around it and if you have enough of these holes it can be completely solid plastic in that area.  Then to make it better, don't have the holes quite reach the outer skin of your part so they aren't visible from the outside of the part.

     

    The nice thing about this is you can give your STL to other people and they can use other slicers and it will work with all slicers and with all "normal" settings.
