What will happen if I try to print an impossible solid into a 3D printer?

Question

What would be the result of a 3D modeled impossible solid, like the Penrose Triangle, printed out of a 3D printer?

Answer 1

Gershon Elber of the Computer Science Department at Technion in Isreal works on creating similar objects by way of introducing contortions of 3D printed media, that when viewed from the right angle, produce the appropriate visual illusion of an impossible objects.

Here is his work on Escher For Real and a Youtube video demonstrating the technique and 3D printed fabrication.
