I thought it might be. I guess the channels along the aluminium resonate and cause the sound. It's no big deal. In fact it'll give me something to do - try to make it quieter :D
I've done a bit of research into the frame and think I'll be going with standard 20mm slotted aluminium. It's cheap and lightweight. I've found what looks to be a pretty reasonably priced supplier, who offers cutting to size, so I wont need to worry about picking up any power tools or fancy saws to cut them up. For anyone interested, it was the first ones on this page: [www.aluminium-profile.co.uk]
I've found a few people's projects on thingiverse that have used the same style 20mm bars, and have provided stls for the frame, which I can print out on my i3.
From what I can tell it'll be a lot simpler to plan this out than a standard printer will be. If I'm not mistaken, I've now just got to sort out how best to mount the three axis to the frame, and then things like belts vs threaded rod, etc
