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.
Hi Butte, thanks for your comments.
Yes, the majority of the cost is for the shredder from 3DEvo.. it works very well and can be used safely in schools with CE certification. I think it´s the best, fastest and smallest solution as the flake size is critical for the smooth flow of PET flakes through the 3d printer.
Our 3d printer is designed specifically for the Spanish guy Mahor´s extruder. We are partners in this and have made several major changes over three years to run directly from ground PET Bottles. The printer contains a Smoothieboard and high quality components that we have tested thoroughly.
For us, it´s the first modular system that people can use PET waste bottles to 3d print with.
It can run most types of plastic, though we prefer PET as we have tonnes of waste bottles and the prints are strong and transparent.
We still need to include an efficient flakes separator… but it´s coming soon..
With one Grinder it can feed about 5 x 3d printers, so with more sales we can get the price down.
Just the transport alone for a 50kg pallet shipment is expensive but it´s all we have to work with for now.
I hope this justifies the cost 🙂
I´m happy to answer all questions and thanks.
I am doing the same and actually I got the same shredder that you have.
I have done full process with extrusion of PLA from beer cup (see the image attached of the final object)
and my next step is the PET bottles
I’ll send an email to get in touch and share the process with you and see what is your process

We have big version of those
Do you have available to buy?
@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.
Something like this is just what i’m looking for, so an open source design for a PP 3d printer would be amazing!
The smoothieboard looks like an awesome piece of kit too
@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 😉
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…
@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?
@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 🙂
