Start your 3D printing workflow with the latest beta of Ultimaker Cura, which offers new features, tools, and stability to make your 3D printing experience better than ever before. Ultimaker Cura 3.4 beta includes new integrated plugins for AutoDesk Inventor 2018, Blender, FreeCAD, and OpenSCAD, among others. Additionally, you can back up your Ultimaker Cura settings so you can retain your settings whether you are in the office or at home. Read on to learn about the latest highlights of the new version.
Please note: We have thoroughly tested this beta, and it offers new and improved features. However, it is still in the beta stage, which means we cannot guarantee the same printing reliability as the stable version. If you are working on an important project, we strongly recommend using the latest official version of Ultimaker Cura.
UX Enhancements
Setting filter timeout. For better performance, the setting filter now activates on input or after a 500 ms timeout.
Import auto-select model. Ability to independently choose the behavior settings preference for newly imported models.
Event measurement. For basic testing purposes, event duration measurements have been added to the log, including boot-up time, file loading time, number of objects on the platform during slicing, slicing duration, and the ability to move objects on the print platform.
Setting error assistant. Detects and displays potential setting file errors to the user, such as incorrect and duplicate entries in material or quality setting files. Messages are stored and sent to the user to prevent the same errors from occurring in the future.
Upgradable bundled resources. It is now possible to install bundled resources with multiple versions: the bundled version and a downloaded upgrade. If already upgraded, the bundled version will not be loaded. If not, Ultimaker Cura will revert to the bundled version.
Plugin Updates
Toolbox. The plugin browser has been redesigned into a toolbox, with graphical elements providing more information about available plugins.
Cura Backup. After installation, you can back up your Ultimaker Cura settings, materials, and plugins to the cloud. Create an account on our secure servers to conveniently store your settings whether you are at home or in the office.

Back up and restore settings on multiple computers.
AutoDesk Inventor Integration. Open AutoDesk Inventor files (parts, assemblies, drawings) directly in Ultimaker Cura.
Blender Integration. Open Blender files directly in Ultimaker Cura.
OpenSCAD Integration. Open OpenSCAD files directly in Ultimaker Cura.
FreeCAD Integration. Open FreeCAD files directly in Ultimaker Cura.
OctoPrint Plugin. A new version of the OctoPrint plugin for Ultimaker Cura.

Slicing Engine Upgrades
Infill Support. When enabled, infill is only generated when needed, and specialized support generation algorithms are used to produce internal support structures for the part.
Generate support only where infill support is needed.

Generate support where infill support is needed.
Print outer perimeter before holes. Prioritize outer perimeters before printing holes. By making holes as late as possible, the risk of hole movement on the print platform is reduced. This setting is effective only if outer layers are printed before inner walls.
No retraction when printing support. Previous versions did not have an option to disable retraction movements when printing support, which could cause problems with third-party machines or materials. An option to disable this has now been added.
Supported wall line count. Increased the setting for the number of walls to print support.
Maximum combing resolution. Combing process is kept at least 1.5mm long to prevent buffer loading times.
Avoid collisions with support during runtime. A setting has been added to avoid collisions with support during runtime. This minimizes the risk of the print nozzle hitting the support material.
Cross infill image. An experimental setting that allows you to enter the path to an image to manipulate cross infill and cross infill density. The image will be overlaid on your model. Please note that the density setting may need to be adjusted for the image to be visible.

Use images to manipulate cross infill or cross infill density.
Third-Party Printer and Stability Fixes
Printer definitions for Felix Tec4, Deltacomb, and Rigid3D Mucit have been added.
This version includes many bug fixes for a more stable and good quality user experience. Notable bug fixes are as follows:
Print job name slicing reassembly. Fixed an issue where the print job name reverted to its original name when regenerated.
Message box style. Fixed errors related to message box styles, such as the progress bar overlapping the "Send File" pop-up button.
Naming Curaproject. Fixed an error where saving a project with two "curaprojects" in the file.
Filament diameter line width. Adjusted filament diameter to calculate line width in the GCODE analyzer.
Korean translation. Fixed spelling errors in the Korean translation.
ARM / Mali systems. Fixed graphics pipeline for ARM / Mali systems.
Discard/Retain. Fixed an error where the "Discard or Retain" dialog did not appear when changing materials with custom settings.
No GCODE USB. Fixed cases where the printer did not support GCODE when the USB port was open.
