2How would you describe an impossible solid to a 3d printer? – Alex Becker May 31 '13 at 21:33

1An "impossible" solid is just a solid that, in some 2d projection or viewed from some angle, appears as another solid. That's all. – leonbloy May 31 '13 at 21:33

1None of the modeling software I've used allows you to build impossible shapes. The rules of euclidean geometry are implicitly included in the software. – hasnohat May 31 '13 at 21:38

3"closed as not constructive" How appropriate :D – Joni May 31 '13 at 21:58

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.
