Printing complex shapes: A sugar chain

Sugar Chain We made this chain of twelve giant links on the CandyFab 4000 to demonstrate the fabrication of a complex object, the sort that is difficult to make by conventional machining processes. You can see the 3D model and some build pictures for this monstrosity over at CandyFab.org.

This object also highlights the relatively large build envelope of the CandyFab-- significantly larger than that of most other low end (i.e., under $50k) 3D fabrication systems.

PS for Chemistry geeks: insert joke about long-chain hydrocarbons here.

Wow, fabbed objects are stronger than I would have expected. What material would you compare it to in strength?

I'm hoping you folks can score a 3-d model of a human pancreas sometime.
