> Imagine being able to reliably fill a hole that’s 5mm deep
You can’t inject filament into a hole without it cooling and solidifying at the top. That’s the problem with this whole idea.

You can set tube height to something tiny like 5mm. It takes a fraction of a second to fill that.
As someone who's printed a lot, on fast printers you have to set a minimum layer time because it takes up to 20 seconds for the layer below to solidify, cool to below the glass transition. Plastic is a bad conductor so heat loss through the walls probably isn't as bad as you'd think
