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

Well done!
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

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.

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.

@archireel , Why not just post a description of what you are doing here and let the whole community learn something?
