feature add: angle for top/bottom internal layer generation

Recommended Posts

So I'm printing this part for one of our projects and because of the angles on it the "top layers" value is generating paths where they dont need to be. I understand why it is putting those paths there but it would be nice if you could set the angle at which it decides to generate the top layers. this part is 1 single wall and hollow, so the small paths it is generating because of the top layers cause heat buildup which causes noticeable defects in the print.

DId you try Special Modes -> Spiralize Outer Contour ?

The yellow areas you are indicating is Cura setting up the top/bottom layer thicknesses on shallow overhangs. And the defects you are seeing are probably not heat related, but rather the 'jiggling' Cura does to set up these 'support' layers.

If you don't wish use Spiralize Outer Contour. If you wish to not use that feature, set your Top/Bottom thickness to 1 layer height.

I have to say, I feel the OP's pain.  This phenomena has been a problem for me many times.  The problem with reducing top thickness to 1 layer is that to get a good finish on the actual top, you need 6+ layers depending on the model geometry.

 

True. If it's a dome or a peak (or open) you can get a good finish with just 1 layer, otherwise it's a mess.

If I understand your issue correctly, there could be a solution arriving soon. We're currently working on a feature that expands skin layers when they lie under perimeters because that makes a better job when you have walls above low density infill. The feature also includes the ability to shrink narrow areas of skin such as you have in the image above.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
