Arrange components for additive manufacturing

  1. Ensure that you have an additive setup with an additive machine selected.

    Tip: If you want to define specific areas in the additive machine where printing should be avoided, in the Machine Definition dialog, on the Platform page, upload a .3mf file for the Platform No Build Zone.
  2. On the Manufacture workspace toolbar, click Additive > Position > Arrange arrange icon.

    The Additive Arrange dialog opens.

    Note: Alternatively, if you want to edit a setup's existing arrangement, in the Browser, right-click the Additive Arrange node and choose Edit.

  3. By default, all the components in the setup are automatically selected. The list of components is displayed in the dialog. If you want to change the selection, on the canvas, click the components to select or deselect them.

  4. Select an Arrangement Type to determine how the selected components are arranged in the additive machine’s build volume. Choose:

    • 2D Arrange to place components on a single layer on the build platform.

    • 3D Arrange (Bounding Box) to use components' outer dimensions for a quick and rough arrangement.

    • 3D Arrange (Monte Carlo) to use a random sampling algorithm to find an optimal arrangement that minimizes build height.

    • 3D Arrange (True Shape) to optimize placement based on components' true shape for higher packing density.

      Note: Usually, 3D Arrange (True Shape) is the preferred option to maximize packing efficiency.
  5. Select a Priority Type to determine how to prioritize selected components for arrangement if there is not enough space on the platform to fit all of them in a single setup. Choose:

    • Component to set individual levels of priority for each component that you want to arrange.

    • Volume to automatically prioritize components based on their volume, from largest to smallest.

  6. If you selected the Priority Type of Component, in the components table, set the level of Priority for each component. Those with higher priority levels are preferred in the arrangement.

  7. If you selected the Arrange Type of 3D Arrange (True Shape):

    1. (Optional) To create multiple copies of the components, select the Create Copies checkbox, then enter a Global Quantity multiplier.

      Tip: You can override this global setting for individual components in the Quantity column in the component table.
    2. (Optional) To rotate the components during the arrangement process to help improve the packing efficiency, select the Rotation checkbox, then choose options for Global X Rotation, Global Y Rotation, and Global Z Rotation.

      Tip: You can override this global setting for individual components in the Rotation column in the component table.
  8. (Optional) Adjust the Spacing:

    • Enter a Platform Clearance to set the distance between the bottom of the components and the build platform.

    • Enter a Frame Width to set the distance between the boundary of the arrangement and the edge of the build volume.

    • Enter a Ceiling Clearance to set the distance between the top of the components and the top of the build volume.

    • Enter an Object Spacing to set the minimum distance between components.

  9. If you selected the Arrangement Type of 3D Arrange (Monte Carlo), in the Advanced Settings section:

    1. Move the Performance slider to choose between prioritizing speed or accuracy in the arrangement process.

    2. Choose an Initial Rotation option to determine how the components are rotated before the arrangement process begins.

    3. (Optional) To arrange the components based on their current position, select the Start Arranging from Current Positions checkbox.

  10. Click OK.

    Note: The arrangement process may take several minutes. The length of time can depend on the number of components and the type of arrangement you are using.

Tip: To remove from the setup any components that are outside the build volume, right-click the setup in the Browser and choose Remove Excess Components.
