Base layer peeling
« on: January 16, 2013, 12:56:10 AM »
I've been printing some of the calibration models from thingverse (most notedly the big square with all the holes in it) and I have to stop the build because the base layer keeps peeling up all by itself.

Anyone else have a problem like this?

What can cause it?

Thanks

ABS or PLA?
Polyimide or blue painter's tape surface?
What temperature?

Black ABS from taiwan

Extrude temp is 200C
Polyimide Bed temp is 55C

Those are PLA temperatures. ABS needs the platform at 110-120C and the extruder at 210-230C.

Set the extruder to 220C and the platform to 115C and I still have peeling on larger prints.

Could it be the speed of travel and extrusion?
 
Or do I have crappy abs?

And one of the parts I was printing just got knocked off the platform by the extruder.

Starting to think this ABS sucks.

Could be. I'm not aware of any good ABS filament suppliers in Taiwan. Could also just be fingerprint oil all over the surface. Try wiping it down with acetone (or at least isopropanol) and try again. Also, I find that the tops of those ranges work best for me (especially during the winter), so try 120C and 230C.

I just switched back to the sample ABS that diego sent me and that works even at 200 and 55.  so It's the ABS.

the filament from taiwan seemed legit because the guy offered all the specs.
Unfortunately "not sucking" was not one of the specs.
DON'T BUY FILAMENT FROM TAIWAN ON EBAY.

just bought some good stuff from ultimaker.

thanks!

I found a good way to tell immediately if your ABS is any good is to break a small piece of it when you receive it.

If it breaks apart after a few bends, then it is crap.
The ultimachine stuff breaks after 20-30 cycles of bending.  Good stuff.

Additionally I feel the cheap crap filament will smell more like burning styrofoam (probably a higher percentage of styrene) than the good stuff.

Of the two samples we get with our machines, is one ABS and one PLA? The black filament I received is labelled PLA but the pink one didn't have a label on it.

The pink is PLA.
