Hi folks,
I'm extruding PA-747 at 180C. This is worked fine for a few months, but my prints have started to come out with stripes of grey discoloration.
Most recently I tried to print with a spool that was almost entirely grey filament, and my nozzle jammed (e3dv6) and had to be trashed.
What is going on here?
Thanks!!
Are you using a melt filter nozzle?
You shouldn't ever have to trash a E3Dv6 nozzle btw, as you can soak in acetone and clean.
My PA 747 turns slightly gray at higher temps. I use black colorant almost exclusively so I extrude at 191C anyways and it doesn't affect my prints. The filament turns uniformly light gray when over heated a bit. I was going to ask the same thing, do you have a melt filter? If so, has it been cleaned in a while? Grey streaks and printer jamming sounds like some sort of contaminant is inside your machine.
I don't have a melt filter. Was the kit supposed to come with one?
I soaked the nozzle in acetone but it seemed to have no effect. However, it could be that it's not pure acetone, as it's nail polish remover.

I tried nail polish remover and it was rubbish. As if no acetone at all. You need pure acetone, I got some off eBay here in the UK.

Your kit looks to be a v1.x kit, which does not come with a melt filter nozzle. This was discussed on the Filastruder Kit product page - if the filament is being used with a printer that has a nozzle smaller than 0.6mm, a melt filter nozzle is recommended. Some folks either print with large nozzles or use the filament for things unrelated to 3D printing - those people do not need a melt filter nozzle. Here's a link to one:

It screens out dust, dirt, and debris.

Ahhh gotcha. Sounds good to me. However, does the dust, dirt, and debris simply accumulate inside the filastruder? If so, what is the cleaning procedure?
I'm nearly sold on getting one.
Also is it possible to install without the circlip pliers?
It's not that it accumulates inside the Filastruder, it's that it ends up in your filament. It can come from inside the pellets themselves, the cup you use to transfer to the hopper, etc.
You don't need circlip pliers, they're just easier than using regular pliers.

If you meant how do you clean the melt filter? There are other posts on the topic, but simplistically, remove the nozzle (carefully while hot) the clean out any hit plastic with long nose pliers, and soak the melt filter in acetone (assuming abs) to clean fully.
Ah not bad! Ok I'm sold on it. Thanks everyone!
