Working with Part Settings



Copying a Part

  1. Open the Part View page for the desired part.
  2. Click the Copy Part button in the button near the top of the page.
  3. Optional: Enter a new part name in the Name field and select a destination folder from the Destination Folder drop-down menu.
  4. Click Copy Part.
  5. Optional: Change the new part’s settings in the Part Settings panel on the right-hand side of the page.
  6. If you changed any part settings in step 5: Click Save in the bottom right corner of the page.


Updating the STL File

Note that this option is only enabled for parts that you own, after all changes have been saved.

  1. Open the Part View page for the desired part.
  2. If the part has unsaved changes: Click Save in the bottom right corner.
  3. Select the Update STL button at the top of the screen.
  4. Select the updated STL file from the pop-up directory window and click Open.
  5. Click Save in the bottom right corner of the page.


Submitting a Support Ticket

For troubleshooting and assistance, you can file a support ticket with Markforged Support. If you have difficulty printing a part that you own, follow the instructions below to submit a support ticket, along with a copy of the STL file you're working with, to assist Support in determining the cause of the issue. For other issues, submit a support ticket from

  1. Open the Part View page for the desired part.
  2. Click the Get Support button near the top of the page.
    Note: This button only appears if there is at least one printer registered to your organization.
  3. Select an option from the Issue Category drop-down menu.
  4. Describe the issue that you are experiencing in the Issue Description field.
  5. Select Submit Issue.


Rotating Parts

For ease of use, Eiger’s part orientation tools allow you to select which plane of the part is normal to the print bed. Alternatively, you can manually rotate and orient the part on the print bed.

Automatic Rotation

The automatic rotation feature in Eiger is enabled by default when a part is imported. This feature allows users to choose a plane on their part and mate that plane with the print bed. The feature is also smart enough to recognize parallel planes; if there are multiple faces of the part that have parallel planes, Eiger will mate the print bed to the first surface that comes into contact with it. If the selected surface is part of a concave feature, Eiger will mate the plane for that surface parallel with the print bed, resting the lowest point(s) of the part on the print bed surface.

  1. Open the Part View page for the desired part.
  2. Hover your mouse over and click a face on the part that you would like to make parallel to the print bed.


Manual Rotation

The manual rotation feature in Eiger can be enabled to allow users full rotation about the three axes. The new rotation tool introduces a global axis system where users can take a part in any orientation and drag it to any other orientation. The global axes are defined graphically on the screen and the Euler rotation angles for the part automatically update when the part is moved.

  1. Open the Part View page for the desired part.
  2. Select Manual Rotation in the Part Settings panel at the right of the screen.
  3. Click and drag an axis on the sphere graphic to rotate the part.
  4. Type values in the X, Y, and Z Euler angle boxes to change the part’s rotation, if desired.
    Note: To reset the part to its original orientation at any time, enter 0 for each of the boxes.


Adding Fiber

The most consistently successful prints are those designed with the strengths and limitations of 3D printing in mind. Well-chosen fiber routing can dramatically increase the strength of your parts.

Because fiber is laid down in the XY plane of the part, parts that need strength in a specific direction should be oriented to make the most use of the continuous fibers within a single printed layer. In addition, the plane that will house the fiber must have enough room for the fiber to be printed in a continuous strand. For a Mark Two, Onyx Pro, X5, or X7 printer, the part must have room for 40mm of continuous fiber strand. Due to this constraint, parts with small features may not be able to incorporate fiber.

For more information about printing fiber in small features, please see our blog post about the topic:


Automatic Fiber Routing

If fiber printing is enabled and the geometry of the part allows, then by default fiber is automatically added as a series of sandwich panels, each with a total of six fiber layers. Sandwich panels help ensure part strength while still maintaining an optimal strength-to-weight ratio. For manual fiber routing, or to add or remove fiber from individual layers, see Manual Fiber Routing.

  1. Open the Part View page for the part in question.
  2. Select the desired type of reinforcement material from the Part Settings panel.
  3. Edit any settings within the Materials or Settings tabs, as necessary.
  4. Open the Reinforcement tab.
  5. Set the number of fiber layers to appear in the part.
    Note: This value will be split, with half the layers being placed on the top of the part and half being placed on the bottom.
  6. Select the Fiber Fill Type that you want to use.
  7. If you are using Concentric Fiber fill: Choose which walls you want to reinforce.
    Note: If you are not using Concentric Fiber fill, this option will not appear in the Part Settings panel.
  8. Set the number of Concentric Fiber Rings to appear in the part.
  9. If you are using Isotropic Fiber fill: Set the Fiber Angles for the fiber in the part. 
    Note: If you are not using Isotropic Fiber fill, this option will not appear in the Part Settings panel.
  10. Press the Save button to save the current fiber settings.


Reslicing a Part

At times, it may be necessary to reslice a part -- for instance, when a new software release modifies the Eiger slicer. To force a reslice, select a new print material in the Part Settings panel, save the part, then reselect the original material and save again.
