v2.4.5

  • [Changed] Smooth PA, CFC PA settings, and printing profiles were updated to improve print quality.
  • [Fixed] Exception during slicing if no composite extruder is selected.
  • [Fixed] Incorrect display of composite lines in the Code Viewer.
  • [Fixed] Exception occurring on extruder duplication in printer settings.
  • [Fixed] Typos and mistakes in the UI.

v2.4.4

  • [Added] New parameter “Infill temperature shift” was added to the Overhangs section of the Profile settings. This parameter allows tuning the extruder temperature for overhang infill areas.
  • [Changed] Extruder names are now displayed in the material consumption block after slicing.
  • [Changed] Minor change in the reinforced polygon trajectory correction algorithm, the fiber is now fed on the first correction segment, so the fiber now sticks to the previous layer more reliably at the beginning of the polygon.
  • [Changed] We did multiple internal changes and refactorings to prepare for future features and updates.
  • [Fixed] Exception during slicing of models with full masks.
  • [Fixed] Incorrect total layer number in G-code.
  • [Fixed] Exception during the support generation for very thin models.
  • [Fixed] Error during a project open in rare cases.
  • [Fixed] Fixed minor problem in the fiber consumption calculation.

v2.4.2

  • [Fixed] Incorrect fiber priming line height.
  • [Fixed] Incorrect layer display in Code Viewer (the last layer was missing).
  • [Fixed] Exception during model renaming in some cases.
  • [Fixed] Error while updating Anisoprint settings in the project to the latest version in some cases.
  • [Fixed] Lifetime licenses now have the correct expiration date in the License information window.

v2.4.1

  • [Added] Integration with Formflow topology optimization software. The optimization results can be exported from Formflow and imported into Aura as a part model with a set of masks with defined internal structure (Premium Feature).
  • [Added] The resulting part mass without the support structures and other helper entities is now calculated and displayed after the slicing.
  • [Added] The “Minimum length of reinforced perimeter” setting was added to the Profile settings. Overriding this setting allows printing reinforcements around smaller openings in part.
  • [Added] The part models can now be exported as STL files using the export button on the Models panel.
  • [Added] The list of the recent projects was added to the File menu.
  • [Added] The “Priming line height” setting was added to the Composite settings.
  • [Added] New settings for reinforced entities trajectory correction algorithm were added to the Profile (“Override correction segment speed”, “Сorrection move speed”, “Сorrection move fiber feedrate”).
  • [Added] The “Generate brim in holes” setting was added to the Profile.
  • [Added] The distance between the part and the first brim loop is now configurable in Profile. The small space between the brim and the part outer contour can make the brim easier to remove.
  • [Changed] Tension algorithm was improved. Tension can be applied to shorter straight lines. Also, new settings have been added to the Profile: “Tension fiber feedrate” and “Tension release fraction”. These settings allow control of the fiber feedrate on the tension and release segments.
  • [Changed] More detailed error messages are now displayed in some cases.
  • [Changed] The reinforced entities printing speed no logger rounded to 1 mm/s, resulting in a more smooth movement.
  • [Changed] The bug report form now also sends information about the Aura license.

v2.3.3

  • [Changed] Temperature and Ooze prevention settings for plastic materials are now available for overriding in the EXT edition of Aura.
  • [Changed] Generic PETG and Generic PLA material settings and profiles are now available only in the OPEN edition of Aura. The reason for this is that profiles contain generic settings that should be fine-tuned for any particular material, which is possible only in the OPEN edition.
  • [Changed] ProM postprocessor was updated.
  • [Fixed] Issue with solid infill if “Generate tidy solids on top” option is active.
  • [Fixed] Exception while Loading of STEP files with points, curves, etc.
  • [Fixed] Incorrect behavior if fiber printing is off in profile, but the generation of reinforced infills is on.

New in Aura v2.0

Changes in Aura Projects and Temporary Settings

When you open a project, the settings contained in it are no longer automatically saved to the settings library but imported as temporary. Temporary settings can be used for slicing in the same way as settings from the library, but they will be cleared when creating a new project, opening another project, or restarting the program.

Temporary settings are always displayed at the beginning of the list of settings on the corresponding panel (printers, materials, profiles). Temporary settings can be saved to the library by clicking on the save button. In this case, the custom settings from the project will be added to the library, and the overrides for the settings built into Aura will be overwritten.

Settings Overrides

Each parameter in the settings for materials, profiles, printers can now be overridden, reset, and saved. When a parameter is changed, it becomes overridden. Slicing uses overridden parameters. Overrides are saved across program restart.

All settings can be overridden, including the settings built into the Aura, which are marked with the AP index. The overridden value can be reset to the original (base) value. Also, if the settings are custom (without the AP index), then the overridden parameter values ​​can be saved updating the base ones.

Compatible Materials in Profiles

For profiles, the ability to specify materials compatible with them (plastics and composites) has been added. Also, the profile can be universal – compatible with any materials. In the Slicing panel, the profiles list displays only those profiles that are compatible with the selected materials. All profiles from Aura 1.x are imported as universal.

Composite Settings

Fiber settings were replaced with composite settings. Composite is a combination of fiber and plastic. Composite settings include all the plastic settings that are used in composite printing, for example, print temperature, cooling fan speed, etc. When importing an Aura 1.x project, a composite is created automatically for a combination of fiber and plastic in a composite extruder. When importing fiber settings from Aura 1.x separately, all settings related to the plastic are set to their default values.

Slots and Extruders in Printers

Each printer now has a list of extruder slots and a list of extruders that can be installed in the slots. Before slicing, on the Slicing panel, you can select which extruders are installed in the slots. The tool index and type (plastic, composite or universal) are specified for the slot.

Composer A4, A3 printers have 2 slots – slot 0 (plastic) and slot 1 (composite). Slot 0 can accommodate plastic extruders with different nozzle diameters. Only one composite extruder is currently available for slot 1. The PROM IS 500 printer has 4 universal slots, in which different extruders can be installed.

New Project and Settings File Formats

The new project file format has the .auprojx extension. Projects of the old format (.auproj) can be opened in the new version of Aura, but the project can only be saved in the new format. Settings files (materials, profiles, printers) also have a new format. Old format settings can be imported, settings can only be exported to a new format. An Aura.OPEN license is required to open old projects and settings.

Licensing System

Added licensing system including 3 levels of licenses corresponding to Desktop Anisoprinting packages (NEAT, EXT, OPEN).

Other Changes

  • Plastic extruders with 0.6 mm nozzle diameter have been added to Composer A4, A3 printers.
  • Added “manufacturer” field to material settings.
  • Added the ability to collapse groups of settings in printers, materials, and profiles.
  • The settings for the internal structure of a part, which were previously only available in the Slicing panel, can now be edited in the profile settings (Profiles panel).
  • Confirmation is now requested when deleting printers, profiles, and materials from the library.
  • When selecting extruders for printing various entities (outer shell, filling, etc.), the list now displays not the tool index, but the name of the extruder and the material installed in it.
  • The names of printers, profiles, materials no longer have to be unique, the main identifier of the settings is now id, not the name.
  • Changed captions for settings that were previously marked as (Developer).
  • Plastic consumption is now displayed in grams and cubic centimeters instead of grams and meters.
