Ender3 V2 Bed Surface Tear
« on: September 21, 2021, 08:47:09 am »
Hi,

Am a newbie to 3D printing and so far just printed small objects like bed level calibration and Boaty which always came off the bed easily.
The other day we printed four identical items with larger base areas together with the same PLA (Crealitys own brand purchased with the printer ) at 200/60c , when cold we tried to remove them but very difficult and the third one actually came off with the bed surface attached .
The bed surface is so well bonded to the print we can hardly remove any of it with a sharp blade.

The bed has only been cleaned with IPA as per Crealitys manual.

Have anyone experienced such problems or know why these larger models stuck so fast ?

We have an Overture Bed Surface mat that came with another filament roll, would that or any other bed give better results ?

What printer?  For the CR6 at least, possibly other Creality printers, they state to NOT use IPA on the textured glass bed just dish soap and water.

This works well for me, just need to take care to not touch the build surface after cleaning with fingers as the oils will reduce adhesion.

You did say "when cold" but how long did you wait? Usually if you wait long enough the print will pop off the glass by itself.

But I will admit to being impatient and pulling a print off once, ended up tearing out a chunk of glass.

As said its a Creality Ender3 v2 , the supplied manual states to clean the bed surface with IPA.

Though had since seen some comments on the web to use soap and water so posted that question in Crealitys forum , but no clear answer !  half saying IPA  half soap and water.

So whats a newbie to 3D printing supposed to do, ignore the makers printed manual instructions ??!!   :-//

It was a print for 4 feet extenders which took 10 hours and finished in the middle of the night so the bed was stone cold at about 18c when I tried to remove.

Thinking back to some of the small test objects I tried earlier, did one or two with a raft where the raft was at least as big as these feet extenders yet it came off the bed as easy as anything ?

Have just done a couple of Bed Level prints and they seem fine so nothing gone out there ?
