Irregular ABS Filament

Post by 3D-Print » Fri Mar 13, 2015 9:21 pm

Two sequential print failed for me with my new role of ABS filament from SeeMeCNC where I was sure I plugged the HotEnd. This happened after about 3 hours of a print and again after about an hour of the next print. This AM I was sure I had pluged the tip, but when I came home tonight, I could not get the filament out of the Bowden tube. Even though the tip was hot, I had to take the quick connect fitting off the extruder stepper and use a pair of pliers to remove the filament.

Didn't think much of it, cut off the filament and and tried to load up more filament. After advancing the filament half way down the Bowden tube it bound up. When I removed the filament I felt some irregularities and indeed the irregularities (see photo) is where it was binding.

The image shows pieces cut from the filament I removed plus the part I could not advance. In total that was about 3 feet of filament with all of those Blebs in the filament. I'm trying again with the hope it was a manufacturing joint.

I hope this amount of irregularities highly unusual.

That is a bad roll of filament.

I sùppose it is better than discovering that your spool contains several pieces of filament (not from seemecnc).

Obviously something went wrong during manufacture. Contact seemecnc.

Wow, that aint good... I've found irregularities in filament but never any like that in that quantity. Our source is good about replacing bad spools (infrequent as they are) and I would think Seemecnc will help you out.

This is my sixth, 2 pound spool of filament from SeeMeCNC. I've not had any trouble with prior spools! I expect as you said, there will be no questions about replacement. After changing the spool last night to another SeeMeCNC spool all is working well. :D

Off to work!! :?

SeeMeCNC support is awesome as always. New role is on the way soon!!

Thanks.

I am sorry to hear that the filament had some issues. I can clearly see from the photos that there is indeed an issue. Thanks for the photos by the way!

I will have our shipping department email you a return label today so that you can send that spool back to us. Once we receive the black ABS back I can ship out a new spool to you.

Some one must have been having a bad day at the factory.

It's a pretty common fault with cheap filament, mostly it's just air pockets, occasionally those little bumps can contain foreign bodies which is really bad news especially if they are small enough to enter the hotend and big enough not to get through it.
