Anodization Temperature Test

The CNC kits are undergoing heavy testing, so I wanted to check one of the biggest downsides of some anodized parts: the temperature resistance of the anodization.

Cheap anodization turns brown even as low as 80°C, while LDO uses pigments that are supposed to resist higher temperatures to ensure that the parts keep their black color in your printers.

I tested one part and compared it to the others that weren't in the oven. It was cooked at 110° for 6 hours, then took the first picture, then it went in the oven again at 120° for another 6 hours. In both pictures the heated part is the second from the left, and it shows no signs of discoloration, passing the test with flying colors.

Disclaimer: the test is short and not an assurance of the long term behaviour.
