My point on the price, and yes, perhaps $200 is low, is a return on investment.
An ROI on a $800 filament machine- I am just not sure it is there.
I think, and my math may be off, just doing it in my head, including time, I need to make 90 lbs of filament to pay for the machine.
On Amazon, there are some filament extruders for about $450, that I am not familiar with, so then I get down to about 50 lbs.
That is a lot of material before I pay back the investment.
And this is assuming that I can actually produce high quality, repetitive results.
So I wasn’t being flippant. If someone put one together for a low enough price, I would do it for a hobby. But business wise, not sure it makes sense.
