Hola Mayor.
Saludos, acabo de ver tus vídeos y de tus compañeros me parece un gran avance y de la mano con el medio ambiente, me gustaría tener un extrusor universal. Me gustaría que me mandes más detalle a mi correo gabrielangelencaladaseminario@gmail.com
De antemano te agradezco mucho.

Hola Mahor,
Realmente me gusta tu extrusora. ¿Cómo se compara esto con su extrusora universal de pellets UPE3D2.0?
Me gustaría hacer uno como el tuyo UPE3D.0.
Me preguntaba si podría compartir más detalles sobre cómo lo hizo: la lista de componentes, el modelo del motor paso a paso ... Además, ¿cuánto vendería su modelo 3D CAD? Gracias por cualquier ayuda.

Hola
Estamos con la versión 3, Mándame un correo a mahormuniz@gmail.com para darte mas detalles
Un saludo

any progress on getting parts together? or at least the cad files? I can machine them all myeslf

Email me at mahormuniz@gmail.com
For more information

Hola Mahor , acabo de llegar a este post y estoy flipando con tu ingenio ,es un puntazo para el reciclaje de filamento lo que no entiendo muy bien es si se podria ensamblar en una Anet A8 o tipo prusa y como se haria. Me he suscrito a tu canal para estar al tanto y si hago algun video sobre el tema ,ten por seguro que lo difundiré muy gustosamente.

un abrazo ,mi canal es "djvanbeat" y mi mail "djvanbeatakaianmoor@gmail.com" ,un saludo y mantenme informado.

Hola. Muchas gracias por tu interés en el proyecto, te mando un correo con detalles de la siguiente versión. un saludo

Hola Mahor, vi los videos de Miguel Salmerón haciendo las pruebas, me pareció un gran avance y un inteligente uso del reciclado. Te felicito espero que logres los avances que esperas para el extrusor.

Hola, gracias, pero cuelga el video para que se enteren jaja, https://www.youtube.com/watch?v=U3y28Xm6qKI&t=4s
este es el último avance con pla reciclado https://www.youtube.com/watch?v=LtuMOY-D_vA
si me das tu correo te envío novedades
un saludo

Hola Mahor mi correo es patriciopalavecino@gmail.com. Es cierto! No lo he difundido! lo voy a postear en los sitios de Argentina. Ya lo tienes cocinado!
Saludos!

Hello, wanted to ask is it easy to install this pellet extruder to MakerBot Replicator 2 desktop 3d printer ?

hello, I like your idea to install pellet extruder, but I think that this printer isn't the better option is very expensive for manipule it, I think that you should get larger printer and economic like anet E10 or similar one. comping soon I will design a big format printer with pellet extruder.

Hello Mahor
i'm interreted in creating your pellet extruder and i 'll like to know where you have found your 8 8 145 screw with the different metalic parts

sorry for my late answer, i didnt see your message, the auger is a standard drill wood and the other parts are hand made from stainless steel tube and aluminium sheet, but now I have new design with only two special parts and other are comercial parts. you can see at https://mahorxyz.wordpress.com/2016/05/13/pellet-extruder/

Ciao,

I updated the marlin firmware to 1.1 and it would be cool for anyone working on pellet extruder to provide information so that pellet extrusion will be included into the firmware. For example we could provide the following:

  • the default speed of Nema 17 5:1 geared
  • the retraction settings
    and so on, what do you think?

sorry for my late answer, i didnt see your message, its a great idea increase any configurations in marlin about pellet extruder, other thing that I thinking to include a pressure sensor for calibrate the flow rate like Filament Width Sensor

Are you able to get higher speeds?

with abs it can move at 60-80 mm/sec with 1.2mm nozzle 0.8 mm layer height
https://www.youtube.com/watch?v=do3Xz6amwq8
for pla I need more experience for develop an special auger

Have you tried a larger size nozzle?

yes 2 mm but when larger nozzle is less speed be cause needs more rpms of motor and lost steps with drv drivers

I think I will try for 1.8 or 2

do this support retaction?
I dont think ... :(

yes the retraction settings are between 0.5 and 1.5 and it works see this video

Whoo! IMPRESSIVE! :)

Hey, just saw a video of the extruder working https://www.youtube.com/watch?v=RY7KGiLv_ps
such a great work !!!

I got one question, what is the distance between the drill edge and the nozzle? Did you find differences by adjusting the distance?
I am asking since this is where pellets get melted and enter the nozzle hole.

the distance don't should be less than 2mm for flow, but is good that the auger is into heating zone

ok it make sense
thx

yes I saw the video is upluaded yesterday by Leon Knook he makes great

The metal parts are from? Steel? Aluminium? Do you think aluminium works? And can it work only with the 2 parts near the heaterblocks out of metal and the rest printed?

Thanks for sharing!

Sorry i have not documented the specs of materials would be recomend for each part
Heater block: aluminum for fast heating but iron or steel is ok too. Second heater is not necessary if you use vertical block, view stl files
Heater tube: stainless steel or iron but not aluminum, because it needs thermal break
Auger : iron or steel but not aluminum it needs resist high torque from reducer
Bearing not necessary if use coupling with rubber core. not recommended rigid coupling
Structural parts : alumium for help cooling stepper and reducer. I think that PLA printed or lasser cut metacrilate with fan cooler is ok too,
hopper: printed part

How about copper? Or bronze? Like, printed parts?

Universal Pellet Extruder v3.0
by mahor

Thanks for sharing.. I will see how far I come with printing and Aluminium first.. steel I can´t cnc right now..
The nozzle tube.. steal but how to make the thread fot the nozzle.. you know if there are ready to buy parts like this?

in short time I have the pieces for selling, I´ll tell you

How is the progress on your store? I'm very interested in your extruder.

Im waiting for first pieces for testing, if all right in tree weeks i have more pieces for selling

Please provide information about the parts you sell

great work and design improvements, also a lot of inspiration for my dual pellet extruder for my hackebike project! Btw I had to change to stronger couplers as the common ones have crashed by pellets getting stuck ! Now using geared motors too and next month will start to print CF!

Great work !

Hi Biskero, how are you?, you know that i like your great proyect of hackebike printed with pellet, i follow your shared work, keep it up

Hey, I know thanks a lot! You made a great pellet extruder, will post more news in the coming days !

Let met get this straight: Can I make new PLA wire from my old parts or which failed to print?
so is this to make new example 1.75mm filament?

it's possible to extrude 1.75mm diameter wire changing the nozzle, but the problem is cooling and rolling correctly

Hi,
I didn't see see any reference to the motor's gearset, which would be a good reduction ratio?
Saludos desde Valencia ;)

Hombre por fin un compatriota XD,
the motor is a nema 17 with planetary gearbox 5:1 ratio. for abs works perfect but for pla needs set up ampere trimmer and fast cooling or power suply 24v

Dear Mahor, following ouf previous message you can now how our multi-layer Moineau-based pump
can easily extrude a controlled quantity of viscous plastic PLA, which could be used in RepRap
3D printers: https://www.youtube.com/watch?v=KVAJQfXY_PE This screw pump model, consists of
a steer Auger portion (as yours) which increases the pressure inside a layered double-helix
stator-like container as a layered helical rotor-like is turned.

I have seen your project but i dont understand exactly how double stator helix works, has the spiral in same direction or reversed ?
thank for share

Dear Mahor, details of the Layered Moineau-based pump mechanism can be found at https://osf.io/8yyms -see in particular Figs. 3 and 4. Our layered extrusion mechanism in the continuous limit would become similar to a Moineau pump.

yes, now i understand, so good. really dont needs stepper reducer?

So have you made it and tested it?

yes, you can see videos on https://mahorxyz.wordpress.com/2016/05/13/pellet-extruder/
now i trying to print from 100% recicled PLA, HDPE, PP, etc

Is this to print with or to make new filament with?

I desing it for direct print, less size and less weight, also it can be use for extrude filament with nozzle 1.75 mm, you can see videos at www.mahor.xyz

El ABS que tengo no pasa por el tornillo sin fin las bolitas son mas grandes hasta de 6mm...

yo uso bolitas de unos 3-4mm además de trozos reciclados de mayor tamaño, no entran completamente en el tornillo pero para eso están los dientes de sierra que rompen en pedazos mas pequeños asegurando un flujo continuo.
si aún con los dientes no es suficiente, para el nema 17 puedes ampliar diámetro de broca y tubo a 10mm

Hola Mahor, los pedazos que rompen los dientes de sierra rompen facil porque estal ago ccalientes?, yo he hecho pruebas en frio y nada....

cuando el extremo está a 200 grados en la sierra está sobre 50 ó 60 grados y ayuda a trocearlo sobre todo el PLA que en frío es mas duro. mándame fotos haber si te puedo ayudar mejor, mahormuniz@gmail.com

OK, Gracias por responder solo ensaye con la mano y el tubito sin dientes, ya estoy haciendo pruebas con broca de 3/8", y si pasan sin tanto exfuerzo, todo con la mano....

Otra pregunta que relacion tiene la reductora que utilizastes???

Cordial saludo....

la reductora es 5:1

Nice design.
The bottom fan: how is the air going through the device?
Can you get enough pressure in the extrude head to remove all air from the melt?

The bottom fan maintains cooled the pellets in the hopper, like fan cooler aluminum in filament extruders.
have not any bubble in extruded plastic thank to high internal compression,
Only appears some bubbles if the temperature is too high

Hi guys, i'm glad and thank you for your opinions both goods
and bad, i'd like save the world with printing from waste as faster as possible but not create a war between makers ;) i'd like listen alternatives for bowden systems or other faster mechanics, thank you so much

Hi -we at @SciFabLab are trying with Moineau-based pumps. Follow the on-going project at: https://osf.io/8yyms
The STL files are available at http://www.thingiverse.com/thing:1861347 and the second model at http://www.thingiverse.com/thing:1915577 for a simplified Mini Extruder: Layered Moineau based Pump. For the latter see video: https://www.youtube.com/watch?v=hEEVL4I48Rk Many tests are still needed...

Pellet Extruder with Auger + Moineau screws Version 1.2
Improved Mini Extruder: Layered Moineau based Pump
by encan

It looks good projects :)

Great design!
There is a need for more experimentation towards a reliable and affordable pellet extruder. Other interesting initiatives I've seen on that direction are:
http://upe3d.blogspot.com.es/
http://richrap.blogspot.com.es/2014/12/no-more-filament-quest-for-universal.html

I've just seen the blog link above was also you! :)

http://upe3d.blogspot.com.es/ is old versión of this project, this is second version.

Where to source the metalic parts?

I'm working to get the parts

Looks pretty heavy. Won't allow for fast movements...

You are right, one thing to improve as R&D goes on. I know since I am building my own dual pellet extruder and speed is not a key point at the moment!
Currently dealing with carbon fiber pellets issues!

Also consider that bigger 3d printers will have pellet extruders for sure since cost savings are huge.
Anyway pellet extruders will improve and good design like this one are needed.

https://youtu.be/do3Xz6amwq8 this a real time print, non acelerated. Prints about 40mm/s and 80mm/s travel

That IS very slow :)

HI Opiswahn
I know we in the maker community are sometimes socially impaired, so Im assuming that you are not just being a Jerk for the hell of it..I want to assume that deep in your mind you believe that your comment is in some manner worthwhile and constructive.. so allow me to educate you. You came of as a Dick...
Next time (and Im still ssuming you had some other intention other than trolling) you could post your own remixes which will allow mahor to improve his speed with your input and your designs (of which, by the way, you have posted none).
Is this a perfect solution, perhaps perhaps not, but it is a very valuable effort in that direction. It requires time, experience and effort to design and post a prototype, something you will learn if you post any of your own designs, cause id be delighted to try out your fast 200mm/sec extruder.
Mahor your solid modeling skills rock.....

Ah, and why do you feel offended at all or feel the need to question my intentions?
First, have i mentioned that this is in any case a bad design? I have only stated that this is a heavy peace to move around, with all negative effects that come with it, speed only being one of them.
That beeing said, why do you imply that i do not value Mahor's work? Have i said something like that(in those few words i posted)?
And lastly, why do you feel the need to lecture me? I would advise you to step back, drink a beer and chill out a bit more. NO ONE has been insulted here, NO work has be talked bad about, NO ONE had wrote ANYTHING in bad intention here...

And if this is your thing, running arround and lecturing people than go elsewhere!

Touched a nerve there?
all is well.. all is chilled..

Thank you for standing up for what's right, @ptymaker. It's easy to tell what "makers" have been blinded by privilege their entire life. The lack of appreciation and respect in this community is hurting the overall decorum and many people no longer bother to contribute to the open source community. @opiswahn 's comments serve as a perfect example of what I'm talking about here. Unfortunately, he's not alone in this absurd mind frame.

Dudes... for real now, what is your problem???
The only thing i have done is to mention that the print speed with this design is not that fast. So what. Why am i now the antichrist of the maker community in your eyes?
And what is that absurde mind frame you are brabbeling about?
Again, have i mentioned in any word that i somewhat disrespect mahors design? That i disregard his work??

this looks slow to you ? that extruder is probably much heavier than a conventionnal direct drive filement extruder. So as the famous ad says : hey what did you expect ??? Something twice faster than a bowden one perhaps ?

Once you contribute to the community with your own designs, then you can criticize others. But as of now, there's WAY too many people like you coming here to leech off the open source community and then bitching about it when it's not "good enough" for you. That's my problem.

In other words, to better explain what OPEN SOURCE is all about....

It's a community effort to make amazing things. A developer uploads their work to the open source community, other makers/developers will find ways to improve on that design, until it reaches near perfection.

To sit here doing nothing but using peoples designs for your own good, then bitching about it when it's not good enough for you, is the exact OPPOSITE of what the open source community is all about.

Don't take it personal, you're not alone. In fact, if you were alone, I probably would have just kept my mouth shut. But after seeing this over, and over, and over again, there's a point at which I am going to have to remind people what the open source community is all about.

but considering you are using pellets instead of filament, its super cheap! Basically you pay MANY times the price just to be able to print say at twice the speed most of the times.

this is a experimental project, not an alternative for replace filament printers, for my prototypes of industrial design i use filament printing...

Very nicely done,I really like the way the parts can be cnc milled or laser cut.
This would be great on my future giant delts build,)

Very much looking forward to seeing it printing recycled plastic,HDPE, PP ect.
Great job.

Thank you so much, Very soon i will have the crusher

im looking forward to see it in action please let me know when you have it all together and working please.
