Glass bed for Ender 6

Question

I have a warped glass bed on an Ender 6 that I recently bought. I want to replace this bed. However, the dimensions in which Ender 6 print bed comes (250x250x400 mm) are not available for purchase on sites like Amazon or Creality. Can anyone guide me about which bed I should buy?

Answer 1

If you just want to replace the glass, then you could go to any local glazing/window store and ask for a sheet of glass to be cut to the appropriate size.

It will probably be a lot cheaper than a glass sheet marketed as specific for 3D printers.

There are just one or two caveats:

• Whilst the type of glass is (probably) unimportant (if you aren't using a heated bed) ensure that the sheet of glass that you get your bed cut from is flat. Ask the merchant for glass sheeting that is specifically made as flat as possible, and isn't already warped or with defects.
• If you have a heated bed then you will (most likely) require heat proof glass¹, i.e. borosilicate glass, one example of which is Pyrex. This may be not as easy to source as "normal" glass for windows, but it's still worth asking at your local store.

Note that if the printer was recently purchased then it should still be under warranty and you could ask the supplier to send a new glass sheet.

Footnote

¹ You might (in all likelyhood) get away with just using normal glass plate, in junction with a heated bed, some glass is quite resiliant - it depends upon the quality and/or thickness (re. heat dissipation). Also, when taking into account the lower cost of normal glass, you might not worry about any potential cracking and/or warping. However, if you prefer to err upon the side of caution, then use borosilicate glass.
