alternative to Mic-6 bed plate I am building a toolchanger CoreXY 3D printer. I am in big trouble to find mic-6 aluminium toolplate in my country. Can you suggest me an alternative to mic-6? In my country, I can find easily 5083, 6082, 7005, etc. I don't think, that theese aluminium plates are suitable as heated bed. The design of the bed is the same as the jubilee 3D printer, so it will be best to have minimum warpage.
Most of the aluminium alloys are fine.
When they say that a certain aluminium is not suitable to certain temperature range they usually mean &quot;under stress&quot;... your bed has no stress at all, it's just staying there with basically no weight on top of it.
Also, you don't need the single micron accuracy either...
Just pick a &quot;cast&quot; and milled aluminium and not a rolled one.
If you can choose among different ones, pick the one with the highest thermal conductivity, and that's it. For example, I can easily find milled plates out of 5083 or 7021. 7021 has a better thermal conductivity, which is good to have a more uniform temperature.
