We would like for sure to get the Ultimaker data (both filaments and settings) with pleasure on the website. The database behind is able to handle terabytes of data.
We will add slicers export before the end of 2016 for Cura, Simplify3D, Kissslicer and Slic3r.
Even for UM3, users may be interested into having other options for many reasons like type of plastics, composites, cost, color, etc... They will need a way to find and source them. They will need after to find the right settings.
For the pictures of the settings on the website, they will be added in the next release.
We will release also an explore page where users can see what others printed.
Thanks for the feedback !
