Topic: Nylon 66 Types

Hey, I'm getting ready to buy my first Filastruder, before I get it though, I want to get some feedback on whether one (or all) of these types of Nylon 66 will likely extrude. I know the early 3d printers used to use weed whacker line for filament (which was usually made out of Nylon 66 with some glass fiber and addatives). I also asked Taulman about nylon 66, and he said he successfully made filament out of it. However, I'm also the one who had Ggalisky try to make filament out of the black nylon 66 that he couldn't extrude (that was some surplus off of ebay that I had no information on).

I know nylon 66 has not been successfully tested yet, but I'm willing to try it. I can get one of these different types of nylon 66 and I wanted to know which one would most likely be able to extrude into filament.

The only differences between them are one seems to be a base plastic, one is lubricated, and the other is internally lubricated. I don't know the differences are between these properties, or whether they will affect making filament with them or using them as printer filament. If you know, please share smile. There are a few other types like "nucleated" and "low flow" but I don't know if those properties are important. I can find the sheets for those as well if they are.

Re: Nylon 66 Types

How did it go with Nylon extrusion? I am planning to extrude some Nylon too (http://3dsupplysource.com/materials/raw_material/PA-612)

What kind of extra measures did you take to keep the Nylon pellets dry ?

Re: Nylon 66 Types

dineshwong I haven't yet. Also it's a different type of nylon than what you are looking at. You're looking at 6/12, I'm looking at 6/6. I know for certain you'll need a food dehydrator (for use with plastic only!) to dry the pellets before extrusion. you'll almost also for certain need to seal off the roll to keep it dry.

Re: Nylon 66 Types

Yeah, mine would be different from yours. Was just checking about the dehydration process.
What did you mean by 'for use with plastic only' ?
I was expecting to know the answers for the following
how long does it take for dehydration ?
any need to seal the hopper?
kind of storage container ?

A friend of mine suggested using desiccator. not sure if it is effective, might need a vacuum pump too i guess.

Re: Nylon 66 Types

When I say "for use with plastic only" I mean, once you start using the dehydrator for plastic, don't use it for food anymore.

The other information is stuff I've gleaned from other people:
For dehydration time, 4 hours minimum, 8 hours maximum.
If the pellets have been freshly dried, you should be able to extrude without sealing the hopper. I remember reading somewhere that Nylon will begin being affected by water vapor as soon as 18 hours after drying, so as long as you extrude then seal it with a desiccant pack you should be good.
For storage I think you have three options:
1. put it in a water tight container (they sell them at the container store) with a desiccant pack or two.
2. use a food sealer and a big bag and seal it. (preferably with a desiccant pack)
3. put it in a big ziploc bag, with a desiccant pack or two, squeeze as much air as you can out, and seal it. (can't guarantee this one, but it's the cheapest).

Re: Nylon 66 Types

FelixP if the plastic is clean you can wash the food dehydrator and use it for food again... the dehydrator is made out of plastic.


This being said I for the life of me cannot get nylon 6/6 to extrude satisfactorily I am currently building a puller because the nylon tends to just goop out the nozzle and needs to be stretched to a consistent diameter.  It is very frustrating and I have tried almost everything. 

Maybe the nylon I got off ebay is just bad, I don't know what is going on.

Mechanicus, tell me was the nylon you got this?

If it is, that was the nylon 6/6 I got off of ebay and had Ggalisky try to extrude. He wasn't able to make filament out of it either.

Re: Nylon 66 Types

I suspect the problem might be the high flow rate of some Nylon 6/6 types. If I looked at the right numbers these Nylon 6/6 types have a flow rate about 20x larger.

Re: Nylon 66 Types

I've had some success with nylon6, Been planning to write up (took tons of pics) but need to try again anyways, i did manage to print a sweet camera holder for a quadcopter with it and was working on some other things, just hard to dedicate the time to it.

I'm getting back to it now, also used hips as walled supports on a larger print and also as fill to try control the warping since i'm not printing in a chamber yet.

also my first tests were undried and actually turned out fine, besides the bubbles, but had better results undried than dried so far.

going to do 6/12 first since i have 4lbs of it and only 2lbs of 6 left, will try post the results of both soon.

Re: Nylon 66 Types

I got my filastruder over the weekend, and I'll begin assembling it some time tonight or tomorrow. If Nylon 66 doesn't happen to work out I'll probably switch over to Nylon 6.
