We've used similar Build Surfaces to this, with 3M self-adhesive backs exactly like these.
They work fine at first, do just what is said on the tin. No complaints there.
But when they become old and worn, they no longer work well - at least with the PLA filaments we use.
The base layer or raft would come undone on machines making models that had worked repeatably before.
Fair enough, remove the old one, stick on the new one! Not that easy.
Removing the old one can take H O U R S.
The force needed is considerable, so it's wise to remove the bed from your machine, if that is possible.
You do not want to bend the bed or the mechanism, that would be expensive.
Then one can use a hot air gun (or hair dryer) to soften the 3M adhesive and get the removal started.
Sometimes a part of the surface will come off cleanly, more often there is a papery layer still stuck to the bed plate.
Most solvents have no effect, but a glue remover or acetone do seem to help. Not safe indoors! Toxic fumes!
Once all of the build surface is off the bed plate, it is time to clean the plate thoroughly. Near enough is not good enough when you are printing in 3D. So more Acetone/Glue remover and careful use of the scraper to get all the glue residue removed. Green washing-up pads can help with this, as does a couple of rolls of kitchen paper, maybe more.
It's grim work, and unkind to the hands. Proper skin protection is needed when using acetone, since you may be working with it for well over an hour. Don't forget the ventilation!
So, not recommended, especially at over twenty quid for four.
For that money one can get a couple of borosilicate glass beds which are attached with clips.Signstek 3D Printer MK2 MK3 Heated Bed Borosilicate Glass Plate Panel 213*200*3mm
Used with the spray of your choice (we like 3DLAC, one can lasts longer than one of these 3M surfaces) you have a perfect system where you remove the glass bed after printing and pop in another one for the next print.
When the glass plate has cooled, PLA prints usually pop off by themselves.
