Hi all,

i have a weird problem with one of my filaments. It just dont want to stick to the plate at first layer. I have more than 100h of print time at my UM2, and never had such problems with any filament, I used this one before too and everything was ok. But now i cant get it to stick to the plate.

Its this filament:

I tried same models with another filaments and everything was good.

I cant print any model with this...

After many of tries the first layer was set but then, just pushed to side after going new layer....3 times:

I tried temp from 200°C to 250°C and bed temp from 60°C to 95°C, nothing helps. It says that the filament is ABS but it comes better at lower temperatures from the nozzle, at 250 it comes more white than blue.

Glue dont help too, its the same.

Please a advice, thanks!

    check out my method I posted here

    http://umforum.ultimaker.com/index.php?/topic/3955-any-advice-on-how-to-get-abs-to-stick-to-the-glass-solved/

    I'm finding lately that more and more often, ABS print temps are dropping. When I first started 3D printing, 260 C was absolutely necessary... now I'm getting away with 230~235 with most quality filaments (additives?)

    print bed should be 100~110 (I use 100 C with the ABS slurry)

    enclosing the chamber helps as well (especially for warp-prone parts) but isn't absolutely necessary for smaller parts. Turn fan to 0~25% (not the 50%... although that's not really relevant for you becasue they shouldn't be coming on anyways until a couple more layers in)

    If it still won't stick, send the crap back cuz it aint ABS :)
