I'm wondering this myself. I think I might be able to make sturdier panels for assembly. My alternatives would be printing templates on cardstock alone and glueing two pages together or using corrugated cardboard.
I'm sure you could reinforce the parts in a way that they become as solid as a brick. 
IF you use chipboard, I would suggest concentrating on the actual thickness of the material. Go to Harbor Freight and get a good digital caliper (they cost between $20.00 - $40.00 USD).
Thank you. I'm still considering it. I think I'm going to start by laminating cardstock and build one that way first. I think could build interior struts for reinforcement. If I'm not satisfied I might consider chipboard or corrugated cardboard.I'm a big fan of cereal boxes and corrugated packaging boxes. You can laminate as many layers as possible and at the same time you are recycling resources because the boxes would go into the trash otherwise. Of course one layer of chipboard may be stronger than one layer of regular card, so I understand what you want to achieve. I for myself have never used chipboard because so far it has not been necessary to get it for my purposes (I have to order everything online). I'd like to see what you can do with it, so I'm not against using it.
Did you say 1110 lb?! What is that like a half a foot thick!?1110 lb. card stock, and 67 lb. card stock, through laminating, should be enough for all your needs. By laminating the 110 lb. stock, and placing that part under a pile of books, the resulting piece will be incredibly solid.
No.... its about the same thickness as playing cards.
