Yes, with a nichrome wire you'll need a method to dial in your voltage. As I've stated in the past this gets really important if you're working with white acrylic as it'll turn yellowish if you overcook it. I have some nichrome wire on a spool but haven't gotten around to setting up version 2 yet. Something about having a CNC and a laser and not enough time for both, and I just bought a 3D printer. I am going to have way too much fun.
