Support material only on buildplate?

Recommended Posts

So, I haven't used my 3D printer for my classes since last May, and Cura had a pretty big upgrade since I had updated the software. I don't do a lot of printing, so I'm still pretty green at this, even after 3 years. I am printing spheres with cutouts in them, and only want to print support material on the part that touches the buildplate (it's printing support material on the inside of the sphere, and it want that to be empty because I can't get the material out), but I can't find that setting any more. I'm using a Lulzbot Mini with Cura v3.3.32, HIPS filament. 


I know this has to be simple, so hoping someone can fill me in. Thank you! I've attached one of the class files as an example.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
