bottom solid layer become bridging

Thu Dec 27, 2018 11:39 pm

s3d version: 4.1.1

I print an ice bar model
Add some support on the holder

Printing complete and remove support
All parts are fine, but bottom side of the holder(connect with support)
In preview mode
Layer 19->top of support
Layer 20->bridging
Layer 21->solid layer

In the holder, I think layer 20 should be solid layer not bridging

This layer being a generated bridge is due to the large area and the air gap caused by the support vertical separation layer. If you wish to use solid layer fill settings instead of bridging settings, you can adjust the bridging area threshold to be much less inclusive. A value of 100 rather than 50 may be a good starting point.

Alternatively put 1 layer of dense support ( at 100%) on the top of the support underneath the airborne part of the shape....and change the direction of the support by 90 degrees so the dense layer runs lengthwise down the part.
