3D Printer for PET particles, No filament.. ever

I thought I´d posted this in Foums before… but couldn´t find it in the search…  so here goes again )

We have made a 3D Printer that uses PET bottle flakes.

Any interest in a complete system please message or email me

It´s in the Bazarr here  https://bazar.preciousplastic.com/en/listings/775954-3d-printer-and-grinder-that-uses-pet-flakes-directly

Looks interesting but I can not justify the price.  There is the Spanish guy who has a extruder that does the same thing for a couple hundred euro, and printer costs have fallen so far now days.

 

With the shipping cost it is more than buying a new lathe and 6090 cnc router combined.

@3dseed, ask his majesty @davehakkens and his gang 😉

@leprint, ok …so it’s not the same is it ?
Pellet extruders have been around for years now.

@ occupypp …   are you really PlasticHub…  as it says on the GitHub account ?
Gunter is that you ?  Why do you keep swapping accounts all the time ?

@3dseed

For now we use industrial granulates but in future we want to print from scratchet bottles

@plastikfantastik

The pink lines its water cooling. Machine is not finished yet.  Its normal drill extruder.

@pochoo
You asking about extruder printer or Vase?

@timberstar, yes, you can connect any stepper driver (vimeo.com/115509540). I planned bigger printers over winter but first I’d like to see this in small as David’s printer which I consider one of the first successes for PET printing directly. However, I am documenting the findings and research on github (see ‘print-controller’ which will be just a layer on top of the ‘extrusion-controller’ which is needed by ‘injection controller’ – basically turning the v3 extruder into a small automated bench top factory). If you ‘star’ this on github – you will get notifications for each release and there is every second week something new 🙂

@occupypp It sounds like you are working on something similar to what I want to do, the PP extruder would make a great hot end for large scale printing. Would the smoothieboard run nema 34s?

Its been 12months since we posted the video

We are OpenSource, that´s why you can buy the latest tested designs at http://www.mahor.xyz
Our Auger hot-ends are constantly improving… you can put them on most 3d printers that you buy, or build 🙂

That´s why you can buy copies online…  but they are 12 months old…

@timberstar, ‘smoothie’, it is ! Perfect base to run this in big. I wired today a Nema23 on it and it’s stable and fast (fast enough), great thing to pave the way for printing boats and the like 🙂 I am just curious what to use as frame, holding the v3 extruder. Construction beams seem tempting but probably create too much bouncing or deflection; depends on whether you need a smoothi boat or wavy one 😉

The smoothieboard looks like an awesome piece of kit too

Something like this is just what i’m looking for, so an open source design for a PP 3d printer would be amazing!

@plastikfantastik, it’s a ‘mahor extruder’ as mentioned in the wiki about filament. Since it’s 300E for the whole thing, I ordered some alternatives from robodigg. I am not sure yet it pays out to get this cheaper. As for the required flake size (below 1mm), there is a grinder coming into PP’s portfolio (as addon for all). I just finished testing and it should see the light by November. For the 3d printer, we’re not sure we get one done but most parts are ordered and possibly over Christmas I can fiddle something out, as always : open source.

@leprint, looks great…!!    So are you are using Industrial granules or flakes made directly from the waste plastic ?

@leprint can you please explain the extruder head. What are the pink lines for? Could you show a picture of the whole machine.

Do you have available to buy?

We have big version of those

Sure @s2019 I’ll do that as soon as I have something relevant from my side. But for now I have not tried yet PET and I am eager to learn too on that topic.
