Size scaling

[etoimene]

What would be the main challenges in scaling this printer up in size a notch or two?
I am tempted. :)

Not an expert, or in university, but I would imagine that scaling up a bed singer too large would either create a really slow printer, or facilitate high forces toward the edge of the bed. It would be really hard to keep anything that isn't balanced about the origin of the bed adhered to the plate.

There are industrial motor controlled rotary tables. Not very fast, though.
If I remember correctly from the video, bed rotation speed is critical for speed of print.
There are large scale extruders. Using small one would be slow, for sure. :)
Balance could be an issue at small scale too.
