Ok so I know I have posted this before  but PLEASE all of the InMoov Nation give this a shot you will not be disappointed.

When you are printing parts on your heated bed no matter ABS or PLA please take a moment to sacrifice a bit of beer (YES BEER) on your print surface. It makes adhesion a snap and release from your print bed a breeze as well. 

I have been using this method for months and have had no problems with adhesion whatsoever.

Please give it a shot you will not be disappointed guaranteed. Makes no mater what kind of beer. Just pour some on and wipe off. (the hopps burning smell is a bit intense but what the hey) When your print is done just sit back have an adult beverage or whatever you prefer and listen for the popping clicking sound this is your print releasing from the printer bed. 

I have had 100% success from this method and have thrown away my blue tape glue sticks and abs slurry mixtures.

Enjoy
