How to print composite part

From this video you will know:

  • how to make a decision about part orientation on the build plate
  • how to set up a project for printing
  • how to reinforce a part with perimeters
  • about the specifics of layers with fiber
  • how to observe inner structure of a reinforced part
  • how to save an Aura project

How to print with plastic

From this video you will know:

  • how to upload model
  • how to modify model
  • how to set-up model for plastic printing
  • what is the Session panel
  • what kind of settings you need to achive the best result
  • how to watch Geometry and G-code
  • how to save G-code for printing

Geometry-Code viewer

Aura has two print process visualizers – geometry and code explorers. Geometry view helps you to understand how a part will be printed while code explorer shows exact print head trajectories. Geometry viewer shows entities such as external shell, plastic perimeters, micro, solid and cellular infills, supports, fiber perimeters and etc. Code viewer represents entities such as travels, moves, pure extrusions, retracts, moves with fiber etc. In both modes you can switch between 3D and 2D mode, you can observe all layers, layer range or one layer. And you can show or hide individual entities and change their colors. In code mode you can also display and read G-code, in future Aura versions we will add possibility to select G-code lines and highlight appropriate code blocks on the model.

Code generation

After you’ve configured models and a printing session as you want, press Generate button to generate geometry and translate in to machine code. During process you can Cancel generation with lose of all progress. When generation is successfully finished the printing time and materials consumption information will appear. Materials consumplion is calculated by length and mass. You can Save to file machine code or open code viewer by pressing View code button.

Adjusting part internal structure

You may want to have non-homogeneous part structure. For example, you may want to reinforce with fiber only bottom and top layers to obtain maximum bending stiffness with small amount of fiber. Or you may want to renforce the bottom layers more than the top. Generally, if you have specific requirements about how the part should be reinforced at different levels, you may achieve the result with layers structure configuration.

After you press a set layer structure button on the model panel, the window changes it’s state to layer structure settings mode.

Layers struct panel

You may copy layer scheme from another model. Just press a button with picker icon and then click on a model from which you want to apply layers structure.

To observe region details and edit region just select it from Regions panel. Configure it’s settings as you need. Keep in mind that regions with same color have same properties and they are connected between themselves. It means, that changes made to one regions will affect other regions with the same color.

  • To add region click on a new region button or click and drag on regions panel. Arter that you can specify lower and upper bounds of the region and press Create button.

Region settings panel
  • To delete region click on a delete button. Notice that you can’t remove the last region. You scheme should contain at least one region.
  • To link region to another click on a button. This opperation fills selected region with the settings from picked region.
  • To unlink region click on a button. This operation doesn’t change current region settings, but now all changes made to other regions will have no effect on this region and all changes in this region will have no effect on ex-linked regions.
  • To switch between regions use buttons. This buttons are only for navigation between regions

After you have finished to configure layup scheme don’t forget to apply changes by pressing Apply button.

Model panel

After you’ve loaded a model you will see it on a build plate placed at the build plate center. You can select a model by double clicking on it. Double click on empty space will deselect a model. Double clicking on a part calls model panel.

Model panel
  • To delete a part from a build plate press a  delete button.
  • To move a model on build plate surface simply press a move button on the model panel. After that you can simply drag an arrows to shift a part along X and Y axes. Or you can manualy specify X and Y offsets in corresponding textboxes which are located at the bottom of a main window. After a part is placed as needed, press Apply or Enter button to finish movement. Or press Cancel or Esc to cancel movement.
  • To rotate a part around it’s center press a rotate button on the model panel. After that you can simply rotate a model using an object manupulator. Or you can manualy specify angles in correstponding textboxes which are located at bottom of a main window. Press Apply or Enter button to finish rotation. Press Cancel or Esc to cancel rotation. After you’ve finished rotation a part will be placed again on a build plate.
  • To resize a part you can press a resize button on the model panel. After that you can input scale values in corresponding textboxes. Press Apply or Enter to finish resizing or click Cancel or Esc to cancel resizing.
  • To clone a part you can press a clone button on the model panel. After that a new part will be created and placed in the build plate center.
  • To set layer structure scheme press a set layer structure button.

Bug report

If you’ve encountered bug while working with Aura or you have any suggestion for Aura improvements, please send us a bug report. You can do this from BUG REPORT panel. Please describe a bug and please attach the project that produce this bug. Full bug description and attachment of project that causes the bug will help us to fix it as soon as possible. If you have a question or you want to attach more files, please send it to


Conflicts dialog emerges if you have conflict with at least one settings item in your project (material or printer or profile). Conflict means that you already have in your Aura settings an item with the same name but with differing settings. For example, you already have Plastics material named “PLA” and flow multiplier = 1. And you want to load the project which contains material “PLA”, and this material has flow multiplier = 1.1. So, this is the conflict and you should solve it before you can continue to work with slicer. You can do it with the Conflict dialog.

  • To override your local settings check a checkbox for appropriate settings.
  • To add the settings from the project as a copy uncheck a checkbox for appropriate settings.


Session is the settings aggregator. You should specify printer, profile, materials in extruders, and choose extruder for each print entity. The part settings that you can see at the bottom of session panel can be adjusted individually for each print. Besides, this settings are not taken into account during profile comparison and conflict determination. So if you load a project from a file, this settings are always overrrided without conflict.

After you’ve configurated session you can press a generate button. If the generate button is disabled check that you have loaded model for slicing and your models have no intersection between themselves.
