You will need a Pc or Mac to convert your work to an industry standard for computer games.
If you just want to get into 3d printing you can do a lot of the work in Nomad. But you will still need a Pc or Mac for tidying your work up and preparing for print.
I now use Blender 3d on my PC for almost everything now. There are a lot of helpful tutorials on YouTube to get you started.
