I have an unlabelled sample size length of black filament, which I thought was ABS.
When I try to print with it I get very messy results. The same object(s) print fine in a grey filament which i know is ABS.
I’m printing multiple copies of a small item 11mm square and about 8mm high overall, with an overhanging top roughly like a small mushroom - a scale model of a dockside mooring bollard.
Most of the ‘travel’ movements leave a thin string of filament behind them, and as the head moves from one object to another on the print bed they cluster together like spiders web, and ruin the print. I also get small lumps under the overhang, where the filament has drooped. That doesn’t happen withthe grey ABS.
One attempt pulled one object off the bed, mixed it up with melted filament, and then dragged all the other copies off the bed too.
With my limited experience, I’m guessing that the hot end temperature is too high (245C), and the plastic is ‘too runny’.
I’m wondering if I’m wrong, and the material is actually PLA? Is there a way to test it to find out?
Would I damage the printer if I try it with PLA settings, and it is ABS after all? If the temperature is too low, I’m guessing the filament just wouldn’t extrude - which I suppose might damage the extruding gears.
