Printed part does not stick on the heated bed

[emilytako]

Hi All,

Good day!

I hope that someone can help me out with an issue I am facing.
I have been printing this part many times (40 times) and recently I found that the part will not stick on the bed and there is warping (lifting) during printing.


On the glass is the creality 10s build surface plate - initial printing causes part to lift up.
So I made a brim (8mm) on the product - part still lift up
I stick a paper tape onto the build surface plate and even use teflon tape to hold the brim down - part looks like it's gonna be ok but after 14 hours the printing is spoiled - please see picture

I do not know what to do now, since I have even raised the bed heating temperature to 80 C. Could I be due to the filament issue?

Thank you in advance.
