<p>Unfortunately, you may have to destroy this part, or the build surface, just to get it off the plate.

<p>EDIT: Per the comment to this answer, an alternate method would be to heat the plate even further, to about 80-90*C, which would heat the PLA beyond its glass transition temperature, softening it and reducing its adhesion.

<p>Your first layer including the brim looks a little close to the plate, which is part of the problem; you <em>really</em> squished that first layer down onto the bed. I would relevel the bed a bit further away, or (if you're happy with how actually level the bed is) set a Z-offset to increase first layer width. There's a very fine balance to be struck here; once you find it, printing (and removing said prints) becomes a lot easier.</p>

<p>In future, a build adhesive like Elmer's glue stick or hairspray (or a dedicated adhesive like 3DLAC or Bed Weld) also doubles as a release agent; the adhesive grabs the extruded plastic to keep it on the plate, but also prevents direct contact between two plastics and thus avoids any chemical bonding between the part and plate. Also consider upgrading to a flexible removable surface, like a magnetic BuildTak surface. Being able to take the bed off the printer and then flex the surface to help  pull a corner free (at which point you can slip a scraper in to lift the rest of it off) is a real boon to these types of situations. </p>

While it is heated, I would also see if the brim can get more easily scraped away.

Since it's only PLA, it should be easily removable if you heat it up to over 80°C too.

Welcome to 3dPrinting.SE! While this is water under the bridge, this print shouldn't need a skirt (extra bed adhesion). With as wide/deep as it is, it should stick just fine. This is the reason you're not getting it off the bed in the first place ... it's stuck *too well*. Again, doesn't help you get it off your bed this time, but think about what you're printing in the future and you shouldn't have this issue again.

This question is flagged as a duplicate.  It might not be a duplicate because most build surfaces are smooth, and your is pebbled.

what kind of surface is this? looks like sand paper or one of this removable ones by prusia. maybe it was not intended to be glued on to the metal surface.

Try something simple first: spread 97+ isopropyl around the edges, and see if that will help loosen the bond.
