Release Notes

v1.27.2

  • [Changed] Avoid crossing perimeters algorithm updated to work better in some special cases.
  • [Fixed] Fixed problem with missing support structures on the first layer under interface support zones.
  • [Fixed] Fixed error in “What’s new” window in Windows 10 1709 and older.

v1.27.1

Read about new supports and overhangs: https://aura.anisoprint.com/docs/supports/

  • [Breaking change] Support settings in Aura 1.27 are partially incompatible with support settings in previous versions. After update to 1.27, please review support settings in your custom profiles. Particularly, airgaps layers are now external shell layers, not thin support layers.
  • [Added] Interface supports. Interface supports are generated between the support structure and the part. The print settings for interface supports can be found in the “Interface support” section of the Profile.
  • [Added] Overhangs. Perimeters and infills in overhang areas can be printed with special settings, which can be set in the “Overhangs” section of the Profile. Solid infill in overhang areas is printed perpendicularly to support structure infill.
  • [Added] New infill type – Zigzag (lines with connections). Support structures printed with zigzag infill can be easily removed.
  • [Added] Added an option to generate support structures from the buildplate only. If the “Generate supports on part” option in the Profile is turned off, supports won’t be generated on the part.
  • [Added] Added an option to print multiple perimeters around support structures. The number of perimeters can also be set to zero.
  • [Added] Added welcome window, which displays the most significant changes after the program update. Also, it can be opened using the main menu (Help > What’s new).
  • [Changed] “Self-support angle” setting substituted to “Self-support distance”. Self-support distance allows better automatic calculation of supported zones.
  • [Changed] The layer height used for airgaps is now the external shell layer height.
  • [Changed] Support settings in default profiles are converted to a new format.
  • [Changed] Improvements of polygon simplification algorithms, improvements of slicing speed.
  • [Changed] Geometry libraries are updated.
  • [Removed] Removed “Thin support layer height” setting. Thin supports layer height is now the same as external shell layer height.
  • [Fixed] Fixed exception in merging close plastic perimeters.
  • [Fixed] Fixed exception in the generation of composite lattice infills.
  • [Fixed] Minor fixes in UI.
  • [Fixed] Small fixes in slicing and code generation.
  • [Fixed] Generation of plastic microinfill for parts with composite infills.
  • [Fixed] Exception during startup when mouse cursor is on the view cube

v1.26.1

  • [Fixed] Exception during filling thin gaps in part

v1.26.0

  • [Added] New print time calculation module, which emulates the motion planner of the printer firmware. The new algorithm takes into account accelerations and extruder heating time on tool changes. New settings were added to the printer configuration: accelerations, extruder heating speed, and buildplate heating speed
  • [Added] Added preheat of inactive extruder before tool change. Preheat can be turned on in plastic settings. Also, the preheat temperature can be specified. The preheat temperature should be between the standby temperature and print temperature. If preheat is on the next extruder will start to heat in advance, when the previous extruder is still printing. The beginning of the preheat is planned based on the heating speed of the extruder and the difference between the standby and preheating temperatures to reach the preheating temperature just before the tool change. Preheat is off by default. Turning it on allows us to reduce extruder switch time, speeding up the print
  • [Changed] Algorithms for filling thin areas with solid infill were reworked
  • [Changed] Algorithms for merging close plastic perimeters were reworked
  • [Added] Gaps between external shell perimeters are now filled with microinfill. Gaps between inner plastic perimeters are now filled with solid infill

  • [Changed] Path planning algorithms improved, resulting in up to 25% fewer travels
  • [Changed] Improved hiding of retracts and unretracts on external perimeters
  • [Changed] Changed layer printing sequence: cellular infill is now printed first, following with internal perimeters, external perimeters, and solid infill. This sequence improves print quality for solid infill and perimeters

The adjustment values are specified in millimeters. Positive values will make the part dimensions and holes dimensions larger. Negative values will make the part dimensions and holes dimensions smaller.
  • [Added] Reinforced entities printing order setting is added to the Reinforced entities section of the profile. This setting allows choosing if the reinforced elements will be printed before plastic or after. “First in layer” means that the reinforced elements will be printed first in the layer, before any plastic elements (this was a default behavior in the previous versions). “Last in layer” means that the reinforced elements will be printed last in the layer, after any plastic elements. “Before external shell” means that all plastic elements except external shell will be printed first in the layer following with the reinforced elements and the external shell will be printed last in the layer.

New Models panel

Now you can observe models not only from the build plate but and from the Models panel too. You can include or exclude a model from the slicing process by clicking on the button that on the right from the model name. All model actions are now available from the Models panel. You can simply select or deselect model by clicking on the item in the list. Also, it is good to select a model by a single click on the model at the build plate itself. You can deselect the selected model by click on it once more.

All models actions (Shift, Rotate, etc.) are disabled before you haven’t selected at least one model. These commands are also available from the menu.

Multi-selection is also available from this version.

New Layup structure paradigm

Now regions can intersect between themselves. The higher region has a higher priority to effect on the model and its slicing process. For the first time when you open the Layup panel for the particular model, the default region will be added automatically. The default region seizes all model height and in duplicates settings from the current profile. You can change the region’s order by replacing them with nearby by clicking on arrows located right from a region’s name label. Also, you can remove regions (except default).

The name of a region is the combination of the lowest height limit and the highest height limit. You can set the region heights by hand typing in the appropriate textboxes and by select layer on the model. To do it just click on the crosshair button. The colored label from the left on region name is a color layer mark. You should consider it as the layer’s legend. This color will be used to show which region settings will be used for a particular layer.

After you’ve finished layup rules editing, you should click by the Apply button to save the changes.

Also, you can find the other buttons near it: Add – to add a new region, Remove all – to remove all regions for this model, Cancel – to exit from Layup set up mode without saving changes, Pick – to pick Layup settings from another model (if it exists).

If the model has layup settings, so you can find the layup settings indicator. By clicking on them you could switch on and switch off layup settings for the particular model. If you switch off layer settings for a model, they will not affect the slicing process.

On the Slicing panel (the most important one) the layup rules switcher is also located. By default, it is switch on and all layup rules are using for slicing process calculation. But you can switch it off and all layup settings will have no effect on the slicing process and Profile settings will be used. 

New Profile-Slicing paradigm

From this Aura version, the Use fiber flag will be located only in Profile and will not be located on the Session panel (which now is Slicing panel). You should think about Use fiber flag as the “Allow” to use fiber flag. You can switch on or switch off each reinforcement type at Slicing panel, but you can switch on or switch off the possibility of generation fiber on the Slicing panel. You should consider this moment when you want to create a new profile. And you should set it up with the thought – will be a new profile using for fiber printing or not.

Briefly, we could define the new paradigm as:
Profile – to set up the printing process in general.
Slicing – to adapt profile settings for a specific model.

New Support form

It is easy to ask a question or to send a bug report. Our support team will contact you by email and will help you with your printing process.
