Could this technology work on very large printers?

I was thinking about the idea of the MOD-T and was wondering if there is a limit to the build platform size. After a certain point, wouldn't weight of the print eventually cause malfunctioning of the printer? I am not all that technical, but I would imagine that this would only be able to be used on smaller printers. Can anyone comment on this?

I'm certainly not going to run the math on it, but I'd say your gut reaction is pretty accurate here. There's quite a lot of frictional problems youd run into once your platform and print weighs more than a few pounds. There are ways to get around those, but not in a way that remains practical compared to existing systems.
