You might be able to print without supports, but the tips of the arms will be hard to get to stick to the build platform unless they're a little "flat" where they touch it. Also, it would help a lot if the arms are at 45 degrees, or steeper.
I think that you are right. I've done a lot of 3D printing, and you have to make sure that everything being printed is supported while it's being printed.
Also, if the arms are supposed to move freely, the easiest way to do that is to print them separately and assemble them after printing.
