i’ve got some feedback from the industry about commercial filament : you need at least 44 professional machines at a price (cheapest, all-in-one machine) for ~8000 Euro to actually make money with filament 
so there won’t be an official statement per-se, so we stick to what makes more sense to make a statement about the v3 extruder :
filament hobbyist use, yes
commercial or normal filament, no
ok then, topic can be closed

Yes and 99% of the actual extrusion for 3d printer filament is based on a add on filament winder. the actual extrusion machine itself is not hard. The real business comes in the winder as it pulls the filament to its proper size.
You will need a cooler, measuring device and winder that all work together.
This was demonstrated in I think v2.
Filastruder as a example had a add on project going, as severla others and well documented. no problem to add their devices to the precious plastic extrusion machine.
We’re compiling all the information about filament making and the PP v3.0 extruder into a dossier here. If you have more to add or change, please sign up on the page to add your contributions on the subject. We’re fully booked this year with other developments but we try to update the PP v3.0 extruder as best we can to make this possible, finally : professional heat bands (100 E the piece), fans with fully integrated PID controllers, temperature and forming equipment after the extruder; our aim is to get this to work below 3000 Euro invest.
@btmetz, i really hope you had a look at this video here; To me there is literally nothing solved when it comes to present PP machines on the subject to the outer world; hobbyist may find this alright for some one-off projects but if it comes to find investors I can tell you, there was nothing but head shaking to our clients.
Yes. Since the filament winder is kind of a done open source project, it is better to refer to the existing body of work rather than duplicate it.
Coming from the 3D printer world, being active in it for years, I guess for me filament is kind of a solved problem.
@thanks @btmetz! I will try to merge your comments into the dossier as best I can. I’d like to eliminate all the “could, if, when” as best as possible and come up with proves just; that’s exactly what people asking me

yes, please @btmetz, let’s narrow this to the constraints I’ve mentioned We need here a clear YES, it’s ready to go, you can make filament, print it and sell it.
Of course DIYers have their machines to recycle their own scrap, the internet is full of that ( and i’ve seen it all). It’s about PP v3 extruder as said; thanks.
there is plenty of info in the reprap forum about making filament. it requires a second filament winding device. plenty of designs on thingiverse, and around the web. This guy has lots of designs out.

ok then, I think making a complete dossier about this story would be still the best; i guess pointing to ‘may be possible, but with lots of efforts and restrictions’ could still support PPs claim about this, plus it may engage creative folks – whose who ask : universities, fablabs – to get something done
deal,
