Print bed base.

@Garfield said in Print bed base.:
Yup - and then you add heat and aren't patient enough to let it equalise - hotter one side than the other = guaranteed bow.
One property of aluminium is that the hotter it gets, the better it becomes at conducting heat. Which means that it's very unlikely to get hotter one side than the other. Which is another reason why it is such a good material to use for a print bed. But of course if you use a very thin plate, and/or apply a lot of heat, and/or constrain the plate against thermal expansion, then anything can happen. Personally, I don't have any problems with my bed. The only time I check the level is when I transport the printer to a show, and I never use mesh or any other form of flatness compensation. Which is why my idea of using the printer itself to lap the bed flat never got any further than being an idea.

I can recommend the website www.aluminyumburada.com for aluminium tooling plates / print bed base. Their unit price is cheaper than clickmetal, but their shipping prices higher since they are based in Turkey. So depending on where you are, this could be an interesting option. This is essentially the same product as Ecocast.
