just come across my first serious flaw in the s3d software.
While the infill is quick to print and easy on the printer. It actually adds very little structural strength to the part.
This is becasue it's like a horizontal spider web. Each layer is not connected to the layer above.

Now with the honeycomb infill in makerware the layers form a coherent structure within the model that makes it incredibly strong.
I've tried breaking the makerware versions of this part at this point and it can't be done with anything short of a lump hammer.
Going to have to reprint a couple of handles in makerware - as the ones printed by s3d with same settings break at a point the makerware ones never have.
So tip: don't print anything you need to have lateral strength in s3d.
And i'll go add this to the features you'd like to see thread at the s3d forum.
