Let me modify my point then.
There are some cases in this hive where the resin is NOT self-standing, it lacks a sufficient base. Curved shapes are only strong as their base is to hold them up against both lateral and vertical pressure.
If you look at the picture labeled Knots of resin you will see it has no base, thus all of its weight it on the roof.
In the curved pillars you can clearly see a *bent* pipe. If the resin was capable of supporting itself all alone in this picture the pipe would have been kept straight by the resin, its not.
And don't misuse the concept of the curve. The design isn't strong because its simply got a curve in it.
A curve with thin supports on the sides curved toward the ceiling will not hold any more weight than the supporting pillars will hold. Simply having a curve in the shape doesn't make it stronger unless its a complete *arch*. One of your pictures details a feature common in gothic cathedrals. Because they wanted very high vaulted ceilings they found that the pillars were too spindly and weak to support the weight of the roof, thus they added flying buttresses outside to prop up the sides. Its a perfect example of how curves don't make strength, arcs with sufficient ground support does.
