5 Important Changes And Enhancements In Cura 3.5 Update
1- Improved overhang wall processing
An improvement in the slicing will give us prints with better overhangs. Cura 3.5 will detect overhang walls and print them with different speeds to have smoother finish. The software will also not start printing perimeters on an overhanging wall. (Contributed by smartavionics)
Both pieces were printed using recommend settings for Ultimaker 3 extended, no other settings were tweaked apart from : 220 Celsius temperature, 0.2 mm layers, 20% infill, with skirt.
Print time for Cura 3.3.1 was 2h51 and 34 gr. For Cura 3.5 it was 2h47 and 33 gr.
2- Prime tower reliability
Cura 3.5 generates prime towers in a different way. Instead of printing layers of different material on top of each other, it will now print one tower inside the other. A little bit like Russian dolls. Each material is printed on top of the same material which resolves the bonding issues between certain materials. Prime towers will now be stronger and more reliable than before.

3- Better infills
Support infill line direction. You can now rotate the direction of the infill line patterns to create stronger supports and reduce artifacts on the final print. (Contributed by fieldOfView)
Extra infill wall line count. Add more walls around the infill to better support top and bottom layers and reduce sagging of those layers. You can have less top and bottom layers for the same quality. Although, this will use a little bit more material. (Contributed by BagelOrb)
Multiply infill. Have stronger infill by multiplying infill lines on the same pattern. (Contributed by BagelOrb)
Removed unnecessary travels by almost always connecting the infills lines that should’ve been connected from the start. (Bug fix)
4- Custom support plugin
Similar to the support blocker, you can now add custom support blocks on your models with a simple click. Install the plugin by going to the Toolbox → Browse Packages → Custom support → Install and then restart Cura. (Contributed by Lokster)
5- Cura settings guide
Have you ever wondered about what a particular setting does? An index plugin will explain settings with text, images and videos for certain settings.
Install the plugin by going to the Toolbox → Browse Packages → Cura Settings Guide → Install and then restart Cura. You will be able to find the Guide under the Extensions tab → Cura Settings Guide → Settings Guide.
