Support Materials

Supports never break away perfectly and so you will always have some clean up to do on a design (unless you have a dual extruder and are using a dissolvable material for support).

Now with that said, the "quality" of your support choice matters on how much work you will have to do. This is almost entirely determined by your slicer, which is one of the many places that the stock XYZware software falls short. I normally slice with Cura, which slices well but it's supports leave much to be desired. Something like Craftware is going to be a lot better at this. Even slic3r which isn't as good as Cura for it's level of detail is still a better choice for automatic support structure, though once again unlike Craftware or Simplify3d, you can't manually change how the support works.

The last and perhaps best choice if you care to do the work is to add your own supports in a 3d modeling program, like Autodesk 123D. You'll get total control over the result and you can slice with whatever you wish and know how your support will work. This does take a lot more time and effort however.

Most importantly no matter which route you decide on, all of them have some sort of method that will allow you to print with the stock XYZware software except for Simplify3d which can print directly. Simply3d is the only software I've mentioned that has a cost, so you can experiment with the rest for free and see if you find a solution that suits you.

Simplify sounds great, but I'm too cheap to pay $150. 

Thanks for all the info!
