Model sticks to bed too well

I'm having a similar problem.. Initially I had problems getting the print to stick to the bed, but now that it sticks and does not come free when printing, it is not possible to remove without damaging the piece. I used the spatula that came with the printer, and tried to be as careful as possible, but the same thing has happened 4 times. I did wash the surface with alcohol before printing - but even scrubbing with alcohol left marks (which can be seen around the base)
This image used a Brim of 4mm, 0mm distance from model. ABS material, printing at 230 with a bed of 70.
Other attempts used raft, and no adhesion with various temps but all are ripping the face off this part.
Any help would be appreciated as I'd prefer to not waste more filament i possible!
(hope this an ok place to post this since I thought it was a similar problem)
Cheers!
I print PLA on a thin film of PVA - PVA wood/fabric glue heavily diluted with 3 parts water, and rollered on with a small paint roller. When the part is cold, pulling on the part tears away the thin film from the glass bed - PVA is water soluble, so you can wet the base of the part to remove the PVA film
I don't print ABS, so don't know if the high temperature would make a difference
Also let the part cool before trying to remove it.
Your brim also looks way way to thin, you might want to re-level your bed and make sure the screws/nuts under the bed are fully tightened (as if they aren't, they come loose and cause a lot of fun to chase problems.)
Howdy, Stranger!
