Topic: beggars filament pelletizer

There were some good ideas on building a pelletizer. My approach to this was to find an extreme cheap and easy way to pelletize filament. Don't laugh about this simple construction. It is only a first idea, - but it works. So let's go ...

I took a Forstner-drill-bit (I do not know the right english idiom) and a 1/2" water pipe. Some drills, some cuts and a drill stand. Look at the pictures ...

If You try to build this on Your own, please be aware of the risks! Speed down Your power drill! Wear eye glasses!

Very nice!

I have thought about selling kits to do this, but it seems the risks of people being stupid are far too high. Well done, though!

Oh Tim...... you know the world so well. smile

In my opinion you are correct for the vast majority of people out there, but then again they are out there and will probably stay there.  Well, we can at least hope so.

If you build it they will come. Then they will make fun of it, tell you it's not worth doing and go home and try to copy you.
If a picture is worth a thousand words then being there is worth a thousand pictures.

Re: beggars filament pelletizer

hi all
nice job
but very dangerous cause  the blades can crunch  the metal tube , stopped the drill and snatch
the  base

Re: beggars filament pelletizer

You are absolutely right fredaxe, it is only a study labeled "dangerous". Everyone should know what he does. It makes only sense for people, who are used to work with "prototypes".
On the other hand I tried to show a concept for a very cheap pelletizer. It has to be developed further.
As You found out yet, the blade could scratch the metal tube. Even if there is no crash, the pellets might be useless because they contain metal parts. The extruder might take the pellets, but the hotend will clog.
My next step is to fix the position of the Forstner-drill-bit (again the question: Is this the right english idiom for this?). Then the most problems should be fixed.
Thank You all for the discussion. Go ahead :-)

That takes care of any metal particles. I've made filament by sweeping up dirt and pellets off the floor before.

Re: beggars filament pelletizer

I've got a melt filter but haven't tried sweeping up what I spilt on the floor.  I guess I threw a lot away I could have used!  I'll have to give that a try.  (I'm kind of a fumble fingers and drop stuff once in a while.  I'm sure no one else does that though)

It is comforting to know I am not the only one who occasionally spills a measuring cup of pellets..
