Ultimaker Cura 3.0 offers:

A brand new UI.  Use recommended settings for quick and easy print setup using intuitive sliders to prepare your print, or use custom settings to individually tweak over 200 unique slicing parameters.

Reduced print time and material consumption. Recommended mode has new default settings that aim to save print time, material usage, and material costs.

Professional plugin integration. Seamlessly integrate Ultimaker Cura into your workflow. Use it with industry-standard CAD software packages such as SolidWorks and Siemens NX, or develop your own custom plugins to meet your specific demands.

The following shows a selection of features, improvements and bug fixes in Ultimaker Cura 3.0:

UI improvements

Ultimaker Cura 3.0 UI
Ultimaker Cura 3.0 features a completely updated UI and color scheme.

Faster start-up. Start-up speed has been cut in half compared to the previous version.

Redesigned splash screen. The splash screen has been redesigned to reflect the new interface.

Sliders. Recommended mode now uses sliders to alter slicing parameters:

  • Layer height and print speed. Easily control print quality in proportion to print speed.
  • Infill. Infill density is now easily adjusted with a slider with increments of 10%.
Sliders in recommended mode
Easily control print features with intuitive sliders.

Rasterized build plate. The build plate now shows graduations of 10 mm and 1 mm for more accurate model positioning.

Extruder buttons. Extruder buttons have changed from tabs to buttons, and button colors have been changed to match the new color scheme.

Layer view position. The layer view drop down box has moved from the bottom-left corner to the top-right corner.

Print time location. The print time location has moved from the bottom-right corner of the 3D viewer to the left of the Print over Network/Save to File button.

Tab width. The width of tab functionality will change according to the word space (supported across multiple languages).

Third-party plugins and CAD integration

Third-party plugin capabilities. Professionals can now get the most from Ultimaker Cura by developing their own plugins to streamline their workflow. SolidWorks and Siemens NX compatible plugins are currently available and can be found in the Plugin Browser. Plugins can be installed with a single click, and updates will automatically be pushed when they are available.

Plugin browser
The Plugin Browser is a convenient way to manage plugins for Ultimaker Cura.

SolidWorks integration. Compatible with SolidWorks 2016 and above, this plugin enables seamless integration between the two pieces of software.

SolidWorks integration - design
Prepare your design in SolidWorks.
SolidWorks integration - send to Ultimaker Cura
Press the “Export to Ultimaker Cura” button.
SolidWorks integration - prepare for print
Ultimaker Cura will open, with your design imported, ready to be sliced and printed.

Siemens NX integration. Designs created in Siemens NX can be pushed to Ultimaker Cura at the click of a button. If a design is modified in Siemens NX, it can be updated in Ultimaker Cura by clicking the button again. This plugin is compatible with Siemens NX 10 and 11.

New slicing features

PVA gradual support. Printing times and material consumption are heavily reduced by printing a lower PVA infill in the support and increasing it towards the top. This also reduces PVA dissolving times. On the (extra) fine and normal quality setting, PVA infill layers are printed at double thickness, decreasing print time even more.

Gradual support
Infill becomes denser at interfaces, requiring less support material.

The left print was sliced using Cura 2.6. The right print was sliced using Ultimaker Cura 3.0. Note the less-dense supports with the right print – the support gradually increases in density towards the top and at interfaces.

Z seam options. Gives the user control over where to place the seam – hide it in convex corners or in easy to remove locations such as concave corners. This doesn’t let corner angles influence the seam position.

Cross infill. A fractal pattern infill that requires fewer retractions compared to other infill types. This is useful for flexible materials as it causes less material elongation when extruding. The internal structure provided by this gives flexible models greater resistance, while retaining ‘soft’ properties in all directions.

Quarter cubic infill. Similar to tetrahedral (octet) infill, but half of the lines are shifted half of the period up. This pattern sacrifices some rigidity of octet infill for greater toughness.

Skin removal width. Remove thin strips of skin from a model to prevent print head zig-zagging, in turn preventing vibrations. The lack of vibrations will also improve print quality on slight overhangs.

Skin removal width comparison

Skin expand distance. Cutting away skins on steep overhangs makes prints less sturdy. By expanding skins with the thickness of walls, features will be better supported. In addition, features such as towers on top of infill will be stronger.

Skin expand distance comparison

Extra skin wall count. This feature is now enabled by default. Printing extra skin directly on top of infill can lead to gaps, curling and pillowing. This is reduced by printing a wall around the skin first, and also improves the printing speed.

Extra skin wall count

Minimum extrusion for skin. Will prevent Ultimaker Cura 3.0 filling small gaps that are probably filled already, resulting in less strings, better top details, and faster prints.

PVA retractions. PVA retraction length during a print core switch is increased. In combination with the reduced retraction distance and slightly higher max count, this ensures reduced stringing and more reliable results. Minimum travel distance for retraction is decreased, and max count is slightly increased. This significantly reduces stringing, at the cost of slightly increased print time.

Bug fixes

With the help of our community, we have addressed a number of issues related to:

  • Custom material profiles are no longer sent to Ultimaker Cura when connecting to a printer
  • Sync z-hop with layer changes
  • Memory leaks on MacOS
  • Printer name not loaded when project file is opened
  • Doodle3D Wifi box is selected by default on non-Ultimaker 3 machines
