Has anyone else had their Engineering plate surface start bubbling up?

I’ve never used the engineering plate side of my dual sided Bambu High Temperature Plate. I’ve always used the smooth side of that plate. Today I was going to use the Engineering side of the plate for the first time for a print when I noticed an issue. I have several areas where the surface is bubbling up and the largest is raised about 2-3mm. The bubbles are hard and can’t be pushed down, even when the plate is warm. I’m worried that it could damage the nozzle. Is there an easy fox for this?

I’m rather disappointed that a build plate surface that I never used has issues just from being against a heated surface during printing. I expected better quality than this.

I contacted support, however, I assume that it may take a few extra days to hear back due to the holidays and everyone getting new printers.

Sounds like a defect in the plate

I thought that was obvious that it was defective due to the bubbles on the surface.

Bambu Support is sending me a new plate. They said that build plates are considered consumables according to their warranty policy and not normally covered under warranty. However, they are replacing it “as a courtesy.”

Its obviously a manufacturing defect and I expected to get it replaced because the warranty policy covers manufacturing defects in consumables. It shouldn’t have to be replaced “as a courtesy.”

After going through several days of back and forth with support and finally having them agree to replace my defective build plate, I waited 11 days for it to arrive. I opened the package and they sent me the wrong build plate. Not only did they use the slowest shipping possible, but they sent the wrong one. Bambu support has to do better than this.

Now they are sending me a new sticker since they sent me the Cool plate with Engineering plate instead of the High Temp plate with the Engineering plate on the other side. However, it seems that the tracking info shows that they again used the slowest shipping method possible, so I’ll have to wait another 11 days after it ships to get the correct replacement part.

Bambu, you need to do much better with customer support. You shouldn’t use the slowest shipping methods to ship warranty replacement parts when your parts were faulty to begin with.
