Screw this

[johnridley]

I have been printing stuff with the black ABS that I got from Buy3DInk.com - you may remember that I was having a HELL of a time with it clogging my nozzle for a couple of months. I went to printing PLA for a while, then when I came back I was printing from the other end of the roll, having put the big 12# roll onto two rolls. It printed totally great for a week. Then yesterday it started jamming again.

I noticed that when it was printing fine it was smooth and pretty shiny. When it started clogging, it was dull looking and came out in lumps. Clearly it's just badly blended plastic.

Screw it, it's not worth the hassle. I'm buying a roll of black ABS from Ultimachine and throwing this crap in the trash.

Does it have silvery streaks in it? ABS is hydroscopic and becomes difficult to impossible to flow smoothly when it has absorbed enough water.

When I was working injection molding lo these many moons ago, we had dryer-hoppers that we used for ABS and Polycarbonate.

Put an oven at about 180F and let it bale overnight, it might become useful again.

There are no white streaks or any abnormality apparent on the surface of the material. It's an interesting thought though and is certainly worth trying. I will cut off a dozen meters or so and heat it and see what happens.
