scratch built buildings

[hoscaler]

ok so I am new to this but I have access to a laser cutter and am trying to laser cut some buildings but the problem is that the plastic I am using is to soft so it curls like a banana when it is getting cut I don't recall right off hand what kind of material it is but it is pretty soft and flexible. so does any body know of a good material that can be laser cut that is about an 1/8" thick that wont curl? any help would be appreciated

I'd assume brass sheet might work better.

Use the same a s kit makers do, very thin modeling plywood. Don't think I've heard of laser cut plastic, for the reasons you've indicated. I recently bought some laser cut enginehouse doors and windows that are cut from nice fine cardboard. No grain to worry about, seems to be a pretty good material. Of course it is a particular type/size of cardboard, but I don't have any idea what kind.
