Today, we're proud to officially release Cura 2.1.2 after an open beta of 1,5 months. Cura has been completely re-engineered from the ground up for an even more seamless integration between hardware, software, and materials. Together with its intuitive new user interface, it’s now also ready for any future developments. For the beginner, Cura makes 3D printing incredibly easy, and for more advanced users, there are over 200 customizable settings.

Note: make sure to update the firmware of your Ultimaker with this new release of Cura. By doing this your Ultimaker will support the optimized material profiles in Cura.


Select Multiple Objects

You now have the freedom to select and manipulate multiple objects at the same time.


You can now group objects together to make it easier to manipulate multiple objects.


You can now undo and redo your actions, like moving an object or scaling.

Setting Profiles

The new GUI allows custom profiles to load easily and intuitively, directly from Cura.

3MF File Loading Support

We’re happy to report we now support loading 3MF files. This is a new file format similar to AMF, but freely available.

Intuitive Cut-Off Object Bottom

We’ve added a feature that allows you to move objects below the build plate. You can either correct a model with a rough bottom or print only a part of an object. Please note that the implementation greatly differs from the old one where it was a setting.

64-bit Windows Builds

An optimized 64-bit Windows Cura version is now available. This allows loading of larger model files.

Automatic calculations

Cura allows setting a number of lines/layers instead of millimeters. The engine automatically calculates the right settings.

Per-Object Settings

Per-object settings allow you to override individual profile settings per object.


Line width settings added per feature

Global, Walls, Top/Bottom, Infill, Skirt, Support.

Pattern settings improved per feature

Top/Bottom, Infill, Support.


  • Alternate Skin Rotation: helps to combat the pillowing problem on top layers.
  • Alternate Extra Wall: for better infill adhesion.
  • Horizontal Expansion: allows to compensate model x,y-size to get a 1:1 result.


  • (Combing) Avoid Printed Parts: when moving to the next part to print, avoid collisions between the nozzle and other parts which are already printed.


  • Stair step height: Sets the balance between sturdy and hard to remove support. By setting steps of the stair-like bottom of the support resting on the model.
  • ZigZag: a new, infill type that’s easily breakable, introduced specially for support.
  • Support Roofs: a new sub-feature to reduce scars the support leaves on overhangs.
  • Support Towers: specialized support for tiny overhang areas.

Special Modes

Surface Mode: this mode will print the surface of the mesh instead of the enclosed volume. This used to be called ‘Only follow mesh surface’. In addition to the ‘surface mode’ and ‘normal’, a ‘both’ mode has now been added. This ensures all closed volumes are printed as normal and all loose geometry as single walls.


  • Conical Support: a filament cost-reduction feature for support.
  • Draft Shield: prints a protective wall at a set distance around the object that prevents air from hitting the print, reducing warping.
  • Fuzzy Skin: prints the outer walls with a jittering motion to give your object a diffuse finish.
  • Wire Printing: the object is printed with a mid-air / net-like structure, following the mesh surface. The build plate will move up and down during diagonal segments. Though not visible in layer view, you can view the result in other software, such as Repetier Host or


  • Mac OSX 10.7 or Higher
  • Windows Vista or Higher
  • Ubuntu 14.04 or Higher - Only 64-bit versions
  • Cura requires a video card that supports OpenGL 2 or higher.


  • By Ultimaker: Ultimaker Original (no dual extrusion support), Ultimaker Original+, Ultimaker 2 Family, Ultimaker 2+ Family.
  • By 3rd parties: BQ Prusa i3, BQ Witbox, 3D Maker Starter, RigidBot, Malyan M180, German RepRap Neo.
  • There is no dual extrusion support in Cura 2.1.2 yet. Users with an Ultimaker Original who installed the dual extrusion upgrade kit, can use Cura 15.04.



  • Top/Bottom Thickness: can now be changed separately!
  • Extra Skin Wall Count: add extra walls to the top and bottom layers to improve roofs that start on infill material.
  • Remove Overlapping Inner Wall Parts: remove narrow pieces that cause over extrusion on prints.
  • Compensate Wall Overlaps: compensate narrow pieces causing over extrusion on prints.
  • Fill Gaps Between Walls: fills the tiny gaps on narrow prints pieces.
  • Z Seam Alignment: allows you to choose the z-seam location.
  • Ignore Small Z gaps: if unchecked, fixes small Z gaps.


  • Infill Wipe Distance: allows you to increase infill overlap without over extrusion on the shell.
  • Infill Layer Thickness: choose a separate layer thickness for the infill to save time on prints.


Retraction Extra Prima Amount: allows you to compensate for oozed material after a travel move.


Number of Slower Layers: sets the first layer(s) speeds to increase build plate adhesion.


Coasting: prevents oozing by replacing the end of print paths with a short travel move.


Regular/Maximum Fan Speed Threshold: Allows you to set the time a layer must take to linearly go from Regular fan speed to Maximum fan speed.


  • Stair Step Height: allows the support to lie tightly on top of objects, increasing support stability.
  • Join Distance: allows supports to become one, increasing support stability.
  • Horizontal Expansion: adds extra support to the x,y-directions, increasing support stability.
  • Area Smoothing: smooths the outside contour of support structures to minimize resonation of the print head.
