Yet another modification to the extrusion machine.
v3 upgrade screw.
Using 2hp copper wound motor with belt and pulley/sprocket and chain speed reduction.
2 heat zones
Upgraded the heaters to 2.25kw and the barrel is 1.75 inch bar stock, turned down to 40mm OD and the inside is a much tighter tolerance than the sloppy plumbing pipe.
We are about a maximum of 6.4kg per hour extrusion with this screw. Next unit will use the Robot Digg 30mm OD screw.
Hi out there,
my shredder is almost ready. But one crucial detail is unsolved:
how to connect the motor (28mm shaft) to the hex bar (20mm) of the shredder.
For industrial purposes are a ton of expensive couplings available, with a fixed size.
Do you know any low-tech-methods of connecting them together without the use of a lathe?
Hello Everyone in the PP team
So we have been following for years the development and the community and after some time we finally built our machines here in Cairo, Egypt
We are facing some minor problems so first we are seeking the community support for that:
1- The extrsuion machine output seems to be bubbling out of the nozzle even when using the smaller 3 mm nozzle,if not pulled it keeps expanding into a bubble and makes it hard to have a uniform output
2-The bearing support got bent towards the motor, the same problem was reported on the forum before but not much replies. Our extruder is the old design and I know the screw can create forces for the horizontal motor and coupling, but any thoughts?
3- The texture of the output seems rough and uneven, is this more related to speed or heat, too much heat or too low. I think cooling is a factor as well. I know I am asking a lot but we had a late start 🙂
For any people here in Egypt feel free to reach out to grow the community and have impact collaborations
Stay safe everyone
As the title suggests, I need a motor for my shredder but can’t find one with an rpm lower than 2000. So anybody got one for sale or any tips?
I finally bought a motor.
Got this one : https://www.motorcontrolwarehouse.co.uk/tec-worm-gearmotor-2-2kw-20-to-1-1.html
It has a 35mm output shaft with keyway and I’m wondering how to connect it to the shredder shaft.
Is it a good idea to turn the 35mm shaft down to 20mm and buy a 20mm coupling bit?
Or should I try and manufacture myself a 35mm to 20mm coupling?
Thank you for your answers
I’ve just received delivery of the shredder laserparts. Excited to get started with the build!
I’m looking for motors at the moment and I found this one on ebay
I’m not knowledgeable at all and I’m wondering what the “hollow bore” means.
Will I be able to put the hex shaft straight into there? (Once turned to the correct dimension?) Or do I need to find another shaft and some sort of coupler?
There is another motor with a 25mm hollow bore, is that preferable?
Thanks for your help!

i am making the compression machine and i’d like to get it more automated
i am looking into arduinos modules.
so it would be :
-1 arduino uno
-1 max6675 module to get the temperature
-1 dual bridge l298n to command 2 electric cylinders.
-2 electric cylinders
-no cold start of motors before t° has reach 200°
-upper limit switch when 2 moulds are touching each other
-lower limit switch
has it been ever tested ? anyone in the team happy to help me with arduino programmig ?
What works better or/and cheaper?
I have a powerful motor 8,5kw all set and ready to shred but I still need to reduce rotation speed.
Can anyone help me with that?
Separate gear boxes cost a lot (better to buy them together with a motor)
I lean more towards changing frequency but I need some drawings and general market knowledge.
Hey guys and girls!
I am brand new in the community and i was thinking about to combine the shredder and extruder together with one motor so you need much less materials and have a 2 in 1 machine!!!!
For explanation you connect the 2 machines on the same motor or wave!
Does anybody of you tried out these method?
Id like to say thank you for such a nice project! Its fantastic!!!!!
I am traveling right now threw indonesia and see everyday tons of plastic lieing arround or burned on the street!!!! I think THESE project is a big step forward to become plastic precious!!!!
