That's an awesome image. According to Google, 24 (inches per second) =
1.36363636 mph. That would be _awesome_. We just need to gear up the FilaWinder, right? We'll need larger FilaBottles, though. Drink faster!

Seems like we need a nozzle tip that can adjust the orifice size on the fly. It could all be controlled by the filament diameter measuring device Ian and others are working on.

Also if you are getting 24"/sec, I'd like video.

Just over drill the nozzle.

What if we used two or more opposing fans to "trap" the filament within a vortex of air? Since I'm mounting mine vertically, I'll give it whirl in the coming weeks. If somebody else comes up with a better or working solution, please share!

Extruding horizontally, you need to cool it more quickly before it touches the filament guide.
