make a roll for 40$ a kilogram, that is stable in size and tolerant to +/- 5%. I'll buy it from you.

I can't imagine how this would be better if you have a few pictures or video please post other than faster I don't see any advantage and it has to be way less accurateQuote

Fat nozzles are great. Having .7mm layers with a 1mm nozzle is a wonder to behold as it prints. The downside is that you have to print more slowly; that much plastic takes a while to cool, even with fans.
But you have to use 3mm filament. The 1.75mm moves through the hotend so quickly that it doesn't have time to melt properly.

My question is: What is the smallest feasible filament size for 3d printing? There has to be a size that's practically possible, yet still cost effective. It's gone from 3mm to 1.75mm, but could it go lower? And if it could, like Moore's law predicts, how small could it be produced? Could we one day be printing with .4mm filament through a .4mm nozzle? Consider your mind blown.

Since the pressure would be zero or near zero, there shouldn't be any breakage (theoretically). I know it's not possible now, but neither was a smartphone 30 years ago.

there is no way would even be 100th the speed of the production injection molding machine and as far as quality it would be lucky to be 100th of that toQuote

I think the advantage would be near unlimited printing speed. The ability to produce a part faster than an injection mold.

Currently the limit for reprap like machines isn't the extrusion speed but the speed of the rest of the machine. The mechanics just don't hold up to the accelerations needed.

I'm currently using an ordbot with a bowden merlin nozzle. This makes the mass of the printhead minimal. Also i reduced the mass of the bed to a minimum. From the results i get when i near the maximum extrusion speed the merlin nozzle can take it does not look as if a further reduction would make much of a difference. I might be wrong and my next design will at least have x carriage that should not mass more than the one on an Ultimaker.Quote

This is only true with Mendel variant printers which is why I am always surprised any wastes their time with them and why I am always shocked to see another variant with a bed that moves in Y. With a Delta printer or Etch-e-sketch (Tantillus, Ultimaker) style printer you can move the axis far faster than you can extrude. The extruder is by far the limiting factor with those other style machines.
