The best user experience yet

Orthographic view. A new orthographic view brings Ultimaker Cura more in-line with many popular CAD design packages, so you can easily compare the dimensions of your model before you invest time into a print. Find the new view in View > Camera view > Orthographic.

View the projections of your model easily in orthographic view mode

Object list. This new popup list helps you to quickly and easily identify corresponding filenames and models. Click a model in the viewport and its filename will highlight, or click a filename in the list and the corresponding model will highlight. For added convenience, the open or hidden state of the list will persist between sessions.

Easily identify corresponding filenames and models with the object list

Layer view line type. The line type color scheme in the layer view has been tweaked with new colors for infill and support interfaces so that they can be distinguished better. Infill lines now show as orange, and support interfaces are distinguished from regular support with a distinct shade of blue.

Infill lines are now orange
Support interface lines are now a distinct blue

Slice button delay. For more clarity, after clicking ‘Slice’, the slice button text will change to read ‘Processing’ so you are aware that something is happening during any pre-slicing delay.

Nozzle switch prime distance. Certain materials “ooze” more than others during retraction and long moves. vgribinchuk has contributed a new setting that lets you finetune the restart distance, so that the full extrusion width is achieved when resuming a print.

Smart Z seam. A new option to increase the aesthetic quality of your prints has been added to custom mode, under Z seam settings. Smart Z seam works by analyzing your model’s geometry and automatically choosing when to hide or expose the seam, so that visible seams on outer walls are kept to a minimum.

Flow per feature. Control line spacing separately from flow settings. You can now adjust material flow for specific features of your print, such as walls, infill, support, prime towers, and adhesion.

Expanded third-party 3D printer support

Creawsome mod. This version has pulled the Creawsome mod, made by trouch, which adds a lot of print profiles for Creality printers. It includes definitions for Creality CR10 Mini, CR10s, CR10s Pro, CR20, CR20 Pro, Ender 2, Ender 4 and Ender 5, and updates the definitions for CR10, CR10s4, CR10s5 and Ender3.

Greater stability than before

This release fixes issues with font rendering, per-model settings, unnecessary travel moves, prime tower overlaps, printer hostnames, and more.
