Suppose I want to to print several copies of a large, flat object, such as a hollow frame. If I make an STL file consisting of several copies floating just above each other then my 3D printer's software happily generates supports for the upper objects to sit on, as shown below:
My question is, is this a crazy idea? If it will work it seems it has several advantages. I can print more copies at once than if I tried to fit them next to each other on the platform, and if one of the prints fails the ones below it will still be OK. It doesn't take that much more filament than printing them all separately.
I'll probably try it at some point just to see what happens, but it's not something I've heard of people doing before, so I'm wondering if there's a good reason why it won't work or would otherwise not be a good strategy.
