Hello, up to recently I've been using Slic3r for all my prints, and decided to give a try to the new Cura version and found out it was quite an improvement. However, there's a feature that it hasn't (Or I didn't find) that is infill only where needed.
What it does is that it only generates infill for the parts where it's needed as support for the 'roof' of the model.
There are a few prints where I don't need the piece to be so strong, but I need to print it faster, and with less material.
Thank you for your attention.
