2.3.0

Speed improvements
The first thing you will notice is the speed. STL loading is now 10 to 20 times faster, layerview is significantly faster and slicing speed is slightly improved.

Multi Extrusion Support
Machines with multiple extruders are now supported. If you’ve got the Ultimaker Original with the dual extrusion upgrade kit, we’ve got you covered.

Custom Machine Support
It’s now much easier to use Cura with custom machines. You can edit the machine settings when you load a new custom machine.

Improved Position Tool
Place objects precisely where you want them by manually entering the values for the position.

Improved Grouping
It's now possible to transform objects that are already grouped.
Select an individual item in a group or merged object and edit as usual. Just Ctrl + Click and edit away.

Enhanced Profile Management
Profile management is improved. You can now easily see and track changes made to your profiles.

Improved Setting Visibility
Make multiple settings visible at once. The Visibility Overview setting indicates why a setting is not shown in the sidebar even if it is enabled.

Improved time estimation
Time estimations are more accurate. Based on our test time estimations should be within 5% accuracy for Ultimaker printers.

Optional G-code Machine Prefix
Disable the g-code prefix in Preferences. No more UM2_ on your printer display!

Print Weight Estimates
Cura now estimates print weight as well as length.

Automatic Import Configuration
Configurations from older installations of Cura 2.1 are automatically imported into the newest installation.

Slicing features

Infill Types
We've introduced two new infill types: Tetrahedral and Cubic. They change along with the Z-axis for more uniform strength in all directions. There are now 7 infill types to choose from.

Gradual Infill
Now you can change the density of the infill based on the distance from the top layers. Your objects print faster, use less material, while top surfaces have the same quality.

Set Acceleration and Jerk by Feature
You can now set Jerk and Acceleration by feature-type (infill, walls, top/bottom, etc), for more precision.

Outer Wall Offset
If your outer wall line width is smaller than your nozzle size, move the nozzle a bit inward when printing the outer wall, to improve surface quality.

Enhanced Combing
The “No Skin” option allows you to comb over infill only to avoid scars on top surfaces.

Z Hop
Can’t avoid previously printed parts by horizontal moves? The Z Hop Only Over Printed Parts gives you the ability to Z Hop to avoid collisions for better surface quality.

Skin and Wall Overlap
The Skin Overlap setting allows you to overlap the skin lines with the walls for better adhesion.

Control Initial Layer Travel Speed
Set the travel speed of the initial layer(s) to reduce risk of extruder pulling the print from the bed.

Support Interface
It is now possible to print a support bottom as well as a support roof. Support bottoms are placed where the support rests on the model. Printing the support interface with PVA leads to improved surface quality.

Bug fixes
Deleting grouped objects
Duplicating groups
Bridging
Drag and drop on the first run on Windows
Unretraction speeds
Bottom layer in Spiralize mode
Overlap Compensation
Retractions on Raft
Retractions now occur after each object printed in one-at-a-time mode.
Rafts are no longer printed outside of build area.
Spiralize no longer only spiralizes the first printed segment only.
Line distance is now the actual line distance.
Enabling raft doesn’t influence at which height the model is sliced any more.
Brim is now always printed just once.
Support roofs now only occur just below overhang.

Minor changes
Messages are now displayed 30 seconds instead of 10, making it less likely that certain messages are missed.
You are now notified if you try to save to a locked SD card.
Engine log is now included in the application log.
Undo and Redo now work correctly with multiple operations.
The last used folder is now remembered (instead of defaulting to home folder).
Import X3D files.
Made it possible to add multiple Per Model Settings at once.
Bed Level and Checkup procedures for UMO+ can now be done without re-adding machine.
Combing is applied in more cases and results in better paths.
Infill thickness now supports Grid infill also for even multiples of the layer height.
Support is no longer removed by unprintable thin parts of the model.
Support is now generated on each layer it’s supposed to.
Support doesn't go outside overhang areas any more.
Support doesn't remove brim around the object any more.
Brim is now also generated under the support.
Draft shield and Ooze shield get their own brim or raft.
Settings shared between skirt and brim now also activate when brim is selected.
Compensate overlapping wall parts now also works for inner walls.
You can now adjust the speed at which the bed is lowered each layer.
