Try looking at nylon sprockets. They're plenty light and then won't cost you an arm and a leg, and they should hold up unless you're putting a ton of torque through them.

I'm not sure you'd even save enough weight using titanium over steel that it would be worth it for the money.
We used nylon sprockets last year and on final drive they were a disaster. Closer to the motors works OK, If you really want to save weight, There is a sprocket builder in mechanical desktop. Then get aluminum water jetted, the same profile in steel is about 4 times heaver, and nylon is about 1 oz heaver for a 45 tooth #35. Search the web for a how to streaming tutorial on mechanical desk top and inventor sprockets.
