BIQU SSS Super Spring Steel 310×310mm 3D Printer Platform Parts Printing Build Plate PLA PETG for Cr-10 Cr-10s Pro

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.

EDIT - Now with a lot more hours printing experience with this bed I've experienced warping for the first time ever since I started 3d printing which isn't fixable through z offset and specs of the coating have lifted leaving white/silver dots. There's still adhesion but it's been relegated to my test bed for trying out new filament and mods that might ruin a good bed. I think the issue is it being too smooth, the bottom of the prints are a slightly textured glassy feel and the bed is like a 90/10 mix of smooth PEI and textured bed.Old review -Pros-There's great adhesion straight out of the box and it seems to be a relatively even coating on the sheet.-The ink lifts straight away so I'd recommend doing some scrap 1 layer squares over the logo etc... so it doesn't end up on your printsCons-The plate isn't as flexible as alternatives and it's nowhere near as flexible as the videos on youtube of this product so I doubt it's spring steel.-There's no magnet with the sheet so you're paying double the price as sites like banggood etc...Overall I'd recommend it as a great alternative to the current flexible beds out there but not from the sellers on Amazon.

On the plus side, PLA sticks very well.However, the good ends there. Unlike they claim, the prints don’t just pop off when the plate is fully cooled. The blue paint on the edges comes off, the surface scratches easily.The steel (if it is steel) is very flimsy and thin. The magnetic sheet that comes in the kit is very low in strength, and massively overpriced.At £40 for the sheet and magnetic bed, this is an absolute rip off

Totally chuffed with this upgrade from a glass bed.ive tried similar before and they simply did not work.I thought I would give this a whirl again after throwing lots of upgrades on my first gen CR10 including a bed sensor.wow, this is simply great, i was at first a little disappointed that the surface has a mottled effect but ive actually taken to it more now as it makes parts not look 3d printed anymore on the surface.

i wanted a magnetic removable bed for my heavy 310x310 heated bed to replace the borosilicate glass bed and to swap out my bl touch with a more reliable and accurate induction probe, the bss plate arrived in a delivery bag with bubble wrap around the plate and with delivery handling this has warped the plate which would not lay flat, the magnetic sticker is thick and heavier than 3mm borosilicate glass and has less magnetic pull than a fridge magnet and wouldn’t pull the bss plate flat upon adhesion and when heated to 60° the sides would curl up away from the magnetic sticker by around 5mm and if i turned the bss over the edges wouldn’t stick down because of warping from delivery handling due to poor packaging for this type of item so due to the lack of adhesion and heat curling and how flimsy this plate is i definitely would not recommend this product for any 3d printer even if it were clipped on with bull clips...

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.

This works really well. I applied it directly to the aluminum heat bed of my CR10 and it is perfectly flat. The original glass bed was bowed. I had been using blue tape before this and I didn't realize the time I was wasting until I got this. I've only had to level my bed once since I got it and that was when I installed it. It is also double-sided so if you somehow manage to damage one side it's still good. I highly recommend it.

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.
