BIQU SSS Ultra-Flexible Removable Spring Steel Build Plate Surface Heated Bed for Ender 3/Ender3 Pro/Ender3 V2/Ender3 S1/Ender3 S1 Pro/Ender3 V2 Neo/Ender3 Neo/Ender 5 Pro/K1 3D Printer 235x235MM

I use this plate (so far I've only used PLA) on my Artillery Sidewinder X2. So now there is a fairly thick magnetic sheet and a thin steel plate on top of my printer's original glass print bed. If you are doing something similar then you will need to allow more time to heat up these extra layers before starting the print and may also need to set the bed temp a bit higher then you would have done because your new print bed is now further from the thermistor. I now usually run an auto level / z-offset setup sequence before each print just to make sure I've given it plenty of extra time to heat through. The surface of this sheet is only slightly dimpled but the adhesion I have found to be excellent, and so good it stops any warping as well. When the plate is cold the prints come completely free or will pop off if you flex the plate. It does need to cool completely to free up, but you can always remove the plate and pop it in the fridge for a few minutes if you can't wait or the print is too flexible. The plate has two identical sides so will last longer. I like this build surface so much though that having damaged one side of mine I have ordered another.

This steel bed is a lot more flexible than the one that came with my Creality Ender 5 S1. However, the magnets work and is sticks to the heater plate with no issues.I did a quick manual bed level on the corners, adjusted the Z axis offset and set it printing. Adhesion appears good, so looks very promising.This plate does not have locating notches (unique to the Ender 5 S1), but that is a non-issue. Time will tell how long the surface lasts, but it is double sidedAll in all, a good replacement if you damage the bed that came with your printer. Cheap, good adhesion and the flexibility makes removing your prints easier.

I bought the BIQUU SSS kit when they first launched it direct from them.New sheet is much thinner than launch, but works great!But.. if you have a magnet on your bed already and you know it works, leave it, im so glad I never removed mine and put new one on, IT DOES NOT STICK the sheet down, it slides everywhere, I tested with my old SSS sheet and the same, wish I had bought the SSS sheet only, i'll keep the magnet just incase.

Great item I was having issue printing with ABS and TPU filaments but with this build plate, i can print with both with out a issue now, ABS filament sticks to it very well and with small parts I have not had to uses brims or rafts to hold it down it also great for PLA and PETG filament, it is easy to remove models and easy to clean it is double sides but so far I have only had to uses one side, I would recormend it to anyone who prints with ABS filament and is worth the investment

OK let's not beat around the bush, this is an expensive enough build surface, the same or more expensive than some borosilicate. Is it better? Maybe.It suffers from extreme warp compared to a standard glass bed, enough that it is not usable without a printer sporting a probe and mesh leveling. Take a look at the attached visualisation of the bed at 60C.So that said why give this five stars? Once roughly leveled and then letting automatic mesh leveling do its thing the adhesion and final result on this is excellent. To remove the print it really does just fall off when removing and slightly flexing the plate, even single first layer adhesion test squares just pop/slide off.Both sides of the plate are PEI coated so if you ruin one side the other should still be good, also inductive leveling should work due to the steel construction but I cannot confirm, however a BLTouch works perfectly.Basically if you have a printer with a probe and mesh leveling this is only going to make things better, if you don't have these this is probably only going to cause you problems. Invest in a probe and upgrade your firmware first, then add this sheet.

Nicely made but adhesion is not very good.

I installed it on my Elegoo Neptune 2 (after I managed to tear up a bit of the original print surface), re-adjusted my bed level settings, and it worked straight away. Much better adhesion than the original surface, and much easier to remove finished prints. A great replacement, I can definitely recommend it.

OK only for ones who are upgrading from magnetic build surface. It does not come with a magnetic base. Get past these it is really good. It easily bends to remove prints and the prints come away cleanly. It is thinner than other magnetic surfaces but with double usable sides. I mainly print PLA with a 0.6mm nozzle so supports are a little thicker.
