Sometimes I am asked about how to change Cura settings to make supports easier to remove from the final 3d print. 

There is value in looking into support settings, but I usually like to back up a couple of steps. Here are a couple of things that I look at first, and then look at support settings.

• Has the part been designed for 3d printing? If at all possible, keep the build process in mind when creating the design. Minimize the overhangs, for example, to reduce the number of supports that are needed. Obviously, this only applies if you have design authority.
• Orientation. I play around with print orientation quite a bit before I settle on a final print method. Sometimes it’s obvious. For blocky functional components, there is often a square surface that is easy set onto the buildplate. Other times, it’s not so obvious.
• Support settings. Once you’ve considered the 3d printing process, then it’s time to play with the support settings. These will be a function of your machine’s capability and tolerances. As a general rule, make them as close as you can get them to the print without having them welded to the surfaces.
