    Anodizing aluminum frame

    Although I'm happy to have just received my printer, I was slightly disappointed to have received the plain aluminum frame instead of the black finish that I had requested.

    I am in no way dissatisfied with the look of the printer, but it did get me thinking about the possibility of anodizing the frame to my liking. From a cursory search through Google, I learned that anodizing aluminum doesn't seem to require highly expensive materials nor inaccessible tools; the process seems to require just some cheap chemicals and common tools. However, most guides I have come across require sulfuric acid which is a nasty chemical that I wouldn't want to keep around and is also difficult to procure.

    Fortunately, I did find this website:
    This guide recommends using Sodium Bisulfate instead of Sulfuric Acid which is an easily purchasable and disposable chemical used to balance pool pH.

    I from all of what I have read, I gather that anodizing the RapideLite frame is within reach. It may be worth experimenting on some test pieces to get an idea of what sort of results are achievable.

    You will probably have to remove the existing anodize first.

    Hey Dongulus,
    Anodizing yourself is not something to be tried on a whim. :} It's not very expensive to pop it down to a local house and have them do it, whatever color you want (within price that is!). With black, you could do "cold" anodizing, which is a heavier coating and a bit sturdier than "standard". It's about twice as thick.

    Anodizing is a many step process, and requires a power supply of a bunch of amps. I had a setup once (the extended version, 14 steps!), and got rid of it because of how often I didn't use it.

    It's messy, and you need a ventilated area to do it in, with lots of space.

    That said, you can probably pick up a kit (without power supply) for about 800.00 that would do a great job. And if you had the room to set it up, you could do other peoples as well. :} :}
