 I really think abs would be alright to use, then we could print what is needed, what do you all think?:cool::D

I think ABS might work well.  It is more flexible than delrin??
From what I've read, PLA has similar melting point properties as delrin.  I didn't find much about PVA electrical properties, other than it is a good dielectric.  The area were delrin seems out perform PLA is the natural lubricity and machine-ability.  

I think my first filament extruder is going to use something like 1/2" diameter rods as material.  So if needed we could buy delrin rod and make prints out of that.:P
Or.. maybe just make an extruder that takes oversized rods mounted directly to the printer.  Maybe not.. lol

I'm thinking of building a shredder for abs plastic, that way we can take junk Mr. coffee makers, and the like, to recycle abs plastic into usable filament, that way we would not have to buy any rods of any kind.:cool::D:P Most plastic now days has a stamp of what it is.

I plan on that too, but I'm thinking of a two step process.  Grind up plastic, melt it into rods, then extrude it to filament.  I figure that will get rid of air gaps.  I've already found that cheap food choppers don't work. lol

I see said the blind man to the one who couldn't hear.:P What I thought about using was an enclosed dado blade setup that would cut the plastic up into saw dust, or very fine dust, then put the dust in a hopper where an auger forces it into a melting area then through the extruder, to make it any size you want it to be. Also depending on how fast the auger is turning will dictate the pressure inside the extruder. I think doing it this way there wont be any air gaps. I use to work on ice makers that used huge augers 5" diameter, if the auger turned to fast it would lock up because it would compact the ice into a round spiral block no air gaps. The trick is to keep the hopper full, if you don't there will be air gaps. At the melting point along the auger, this is where the plastic should be compacted, auger turning at just the right speed to keep the pressure just right to force the plastic though the extruder, then cooled and spooled.:D:D

sounds like this thread should be moved to the " recycle plastic" thread lol

on the delrin... i guess its up to the end user... the high dielectric property's are why Stan used it to my nonage...

I guess it could be in the recycle thread, but I'm thinking its also a way to process new delrin.  :) Awhile ago I bought some saw blades and bearing to build a saw dust maker.  I wanted to get into making wood pellets from branches.  I just need steel to build the hopper. So many projects...

Yes this could be used for any plastic.
