UltiMaker Cura 4.12-beta

Lightning infill The new lightning infill setting lets you to print high-quality top layers but is optimized to use less material and increase your production speed. Special thanks to @rburema and @BagelOrb!

Improved top surface quality We’ve tweaked the Monotonic setting and made adjustments throughout print profiles. This removes occasional scarring on models and improves top surface quality by default.

Improved horizontal print quality Resulting in reduction of ringing, improving resolution and overall print quality.

App switcher The new switcher provides a simpler way to navigate and use other Ultimaker applications, including Ultimaker Digital Factory, Ultimaker Marketplace, and Ultimaker 3D Printing Academy. Reporting bugs to Github is now just one click away, and it’s easier to find the application you need.

Faster start-up We've shaved 10 seconds from Ultimaker Cura's start-up time by optimizing profile data caching
