The stock heated bed which came on my Creality printer is significantly warped beyond any simple leveling with the screws. Lets say I want to upgrade the stock bed to a premium heated bed, does such a thing even exist? None of the beds I see list any specs or tolerances regarding flatness or deviation.

What should I be looking for to ensure I am looking at a superior bed?

  • $\begingroup$ How about an aluminium heated bed? This might be a useful question for you, although it doesn't deal with warping directly, Do aluminium PCB heatbeds reduce hotspots? I could turn this comment into an answer, if it is useful and relevant... $\endgroup$

If you are only trying to upgrade the "flatness" of the bed and are okay with the heating times you can just put a peice of glass on top. Otherwise you can look into getting a milled tool plate which will be much flatter than a rolled or stamped plate, but you will have to attach your own heating element to this.

  • $\begingroup$ also note that a milled plate is usually a custom ordered part and can be quite expensive, especially if you want to use a really good heat conductor. Copper is about twice as good as aluminium, Steel about half as good (but cheaper) $\endgroup$

  • $\begingroup$ My creality printer came with glass. warped. Flipping the glass upside-down helped slightly, but wasn't great. I tried replacing with a 12" mirrored tile, but the metal bed that the glass attaches to is slightly convex (+/- 0.35mm), so when you clamp down the glass to achieve good heat transfer, it bends any glass on the bed. $\endgroup$

  • $\begingroup$ @davdavis what are you clamping the glass down with? $\endgroup$
