A question on filament: I’ve been trying the various options in ABS filaments available with Prime shipping on Amazon and I’ve run across one that is being… problematic. It’s the “Signstek 1.75mm ABS” in Sky Blue.
Basically, it seems weaker than all of the other filament I’ve tried. I can’t even get it to run through my bowden system without bending and kinking between the drive gear and the bowden tube (this is the only filament I’ve ever seen do this).
When bending it manually, it doesn’t form a slow arc and then spring back, it will very quickly kink and turn white at the bend point then hold that shape.
Is this just bad filament? Or is this a sign of being too wet/too dry/too something and I can rehabilitate it?
True, I have until October 11 to make the return, so that’s what I plan on doing. I was just hoping I was missing something simple so I could actually use it. It’s such a pretty blue… I had such plans for it.
I have what appears to be a bad Jet PLA from Amazon. I can print clear, black, blue, and green just fine, but the red is a nightmare. It’s globby, highly sensitive to cooling, and just a pain to work with. So, yeah, I think you can get bad filament from Amazon, even though I have no experience with the particular one you’re describing.
Generally if it is overheated during production or extrusion it becomes brittle. Sounds like it got cooked to me , while they were making it. My ABS snaps energetically if you bend it too much it doesnt really turn white. Atleast thats my guess after trying about 2.5 lbs of abs of different types.
