Eiger Glossary


2D / 3D View: In the Internal View, choose between viewing the full model as a 3D rendering or individual layers as 2D slices.

Build: A group of parts, all with the same layer height, set up to be printed all together. Builds can be saved, exported as MFP files, or sent to an online printer for printing. For more information, see Builds.

Build Details panel: This panel lists Estimated Print Time (see below), estimated material usage for primary (e.g. plastic or metal) and secondary (e.g. fiber or release) materials, the estimated total cost of that material usage, and any errors or warnings. Values will update upon slicing in the Part View or upon any change in the Internal View. This feature is located on the Build View page.

Build Name field: Name your build in this field, located in the top left corner of the Build View page. Changes to this field are reflected on the Builds page and in the name of the MFP file.

Build View: The page from which you can edit build settings, save a build (which consists of multiple parts), or print / export a build. For more information, see Build View.

Cloud Print Generation: Generate your print in the cloud, allowing for faster print generation and lesser consumption of system resources. This feature is located on the Build View page.

Cloud Slicing: Slice your part in the cloud instead of in your browser, allowing for faster slicing and lesser consumption of system resources. When cloud slicing is enabled, you can navigate away from the page while your part is slicing. This feature is located on the Part View page.

Concentric Fiber Rings: The number of concentric rings of fiber added per layer. Concentric rings help to ensure a smoothly-reinforced external surface where the outermost fibers are always continuous and parallel to the edge of the part. This feature appears on the Part View page when a fiber type is selected from the Reinforcement Material drop-down, and on the Internal View page when Use Fiber is enabled.

Editing Layers box: This feature on the Internal View page allows you to view and edit settings related to the selected layer(s) of the part. Add fiber, pauses, and scans to the print from this panel.

Estimated Print Time: This feature on the Build View page displays the estimated amount of time required to print the part. Estimated print time value will update upon slicing in the Part View or upon any change in the Internal View.

Expand Thin Features: Preserve thin walls or features at the expense of some dimensional accuracy. This feature is located on the Part View page.
Note: This feature is not recommended unless your part has very thin walls which disappear in the Internal View.

Export Build button: Convert the build to an MFP file for offline printing via USB. This feature appears on the Build View page when Export Build is selected from the Select Printer drop-down. Note that exporting a build containing two or more parts will also add that build to the Builds page. 

Fiber Angles: Fiber angles, used only when Isotropic Fill is selected, determine which angles the fiber routing is at for subsequent layers in groups. By default, subsequent Isotropic Fiber layers in a fiber group are automatically rotated by 45-degree angles. Any values in this field should be entered numerically and separated by commas. If there are more subsequent fiber layers than there are entered values, Eiger will iterate through the values in the order they are entered and then will loop back to the first value. This feature appears on the Part View and Internal View pages when Isotropic Fiber is selected from the Fiber Fill Type drop-down.

Fiber Fill Type: Allows you to select one of the following options. This feature appears on the Part View page when a fiber type is selected from the Reinforcement Material drop-down, and on the Internal View page when Use Fiber is enabled.

  • Concentric Fiber: Traces a specific number of shells within the walls of your part, which helps reinforce from bending around the Z axis. By doing so, Concentric Fiber essentially reinforces the walls of the part which prevents the walls from deforming. In this fill type, the print head follows the outer curvature of the part as it spirals inwards, so the more complex that curvature is and the more rings you add, the longer it will take. When using this feature, you can specify how many rings of fiber you want tracing the outline of your part, so you have specific control over how much fiber you are using per layer.

  • Isotropic Fiber: Simulates the individual unidirectional layers of a traditional laminated composite. The pattern effectively creates a unidirectional ‘sheet’ of fiber on each fiber layer by routing all fibers parallel to each other in a single angular orientation, with 180 degree turns when the path reaches the edge of the part. The Isotropic Fiber fill pattern helps resist bending in the XY plane and can also be used to set up sandwich panels to increase torsional strength on that plane.

Fill Density: Modify the internal structure of your part to control its density. Different fill patterns may have different minimum and maximum densities. Note that 37% is the default. This feature is located on the Part View page.

Fill Pattern: Fill patterns are geometric shapes repeated on the inside of a part to add strength. The available fill pattern options are Triangular, Hexagonal (composite only), Rectangular (composite only), and Solid Fill. This feature is located on the Part View page.

Folder: A feature for managing parts that allows you to group related parts together for ease of access. For more information, see Folders.

Generic application data: Both the application code sent from the server to the user to run the application, and schema data sent from the user to the server to verify that user data is not corrupted between updates. This includes information that associates part builds with organizations and users, versioning information, etc. Application data sent from the user to the server does not include any CAD data. For more information, see Eiger Deployments.

Import STL: Button that will allow you to choose an STL file to import into Eiger. For more information, see Importing an STL File.

Internal slice data: The intermediate representation of the sliced STL file that we use in the Internal View.

Internal View: This page allows you to see tool paths and information about how your part will actually print. Use this page to further customize individual layers after editing the part in the Part View. For more information, see Internal View.

Layer Bar: Bar at the bottom of the Internal View, labeled Materials, that represents all the vertical layers which together make up the part. You can enable 2D mode and click within the bar to select one layer, or you can enable 3D mode and click and drag within the bar to select multiple layers; then you can use the Editing Layers box to edit the settings of the selected layer or layers. 

Layer Height: The height (in the Z-direction) of the plastic that is printed in each layer. The default layer height for composite parts is 0.1mm; other options include 0.05mm (Industrial Series only), 0.125mm, 0.2mm, and 0.25mm (Industrial Series only). Taller layer heights will lend to faster prints but may produce a rougher surface finish. Smaller layer heights will have better surface finish but will take longer to print. If you are using fiber in the part, the layer height cannot be changed. This feature is located on the Part View page.

Manual Rotation: Enter Euler angles or click and drag the part preview to orient your part. This feature is located on the Part View page. For more information, see Rotating Parts.

Material drop-down: Choose the primary material (plastic or metal) in which to print the part. This feature is located on the Part View page.

MFP files (MarkForged Print): The raw output of Eiger that Markforged printers use to print your part.

Original Units: Eiger defaults to importing parts in metric units. If your part was exported to an STL using imperial units, you can use this feature to change the import units for a part. This feature is located on the Part View page.

Part Description field: Type a short description of your part that will appear under the name in the top left corner of the screen. This feature is located at the top of the Part Details panel on the Part View page.

Part Name field: Name your part in this field, located in the top left corner of the Part View page. Changes to this field are reflected on the Internal View and Build View pages. If you print this part, its MFP file will save with this name by default.

Part Settings panel: A panel containing multiple tabs that allow you to review and modify part settings, giving you more control over how parts are printed. It contains the following tabs: General, Settings, Infill, and Reinforcement (only appears when a fiber type is selected from the Reinforcement Material drop-down). This feature is located on the Part View page. For more information, see Part View.

Part View: This page displays a model of the part on the print bed and allows you to modify its settings prior to printing. For more information, see Part View.

Pause After Layer: Insert a pause in your print that will occur after the selected layer is finished printing. Pauses can be used for embedding components, changing material, or checking on the status of the print at a specific point. After a pause, the print must be manually resumed from the printer's touch screen. This feature appears on the Internal View page when 2D View is enabled. For more information, see Insert a Pause after a Layer.

Print button: Click to convert the part into a printable file or to directly print to an online printer. This button can be found on the Build View page. For more information, see Printing a Part.
Note: The function of the Print button on the Part View page is to navigate to the Build View page.

Printer Type: Select the series of printer (Desktop, Industrial, Metal, or Mark One) on which to print this part. This feature can be found on the Part View and Build View pages.

Raise Part: Print a raft of supports under your part for better adhesion to the print bed, in the case that the supports on the bottom of the part are too small to remove. This feature appears on the Part View page when Use Supports is enabled.

Reinforcement Material: Select a secondary material with which to reinforce the part, or select None. This feature appears on the Part View page when a composite material is selected from the Material drop-down. When one of the following fiber types are selected from this drop-down, the Reinforcement tab appears at the top of the Part Settings panel. 

  • Fiberglass: Creates strong, tough parts.
    Note: Fiberglass is the only fiber compatible with the Onyx Pro and X5.
  • Carbon Fiber: For the strongest and lightest 3D printed parts available.
  • Kevlar: Impact and abrasion resistant reinforcement.
  • HSHT Glass: Fiber reinforcement for higher temperature environments.

Roof and Floor Layers: Select the number of solid layers of primary material to be printed on the top and bottom of the part. This counter should generally be set to 4. This feature is located on the Part View page.

Rotate: Click a surface and have the part move such that the surface is flush with the print bed. This feature is located on the Part View page. For more information, see Rotating Parts.

Save button: Save the part file by slicing the part with any new printing settings. This feature is located on the Part View and Internal View pages.

Scale field: Change all dimensions of the part by a scaled value. The default of this value is 1, which is the size of the part as it was modeled in your CAD software. This feature is located on the Part View page.
Note: Eiger automatically scales up metal parts to account for the shrinkage that will take place during sintering.

Scan After Layer: Insert a laser scan of your part that will occur after the selected layer is finished printing. Scan data is automatically sent to Eiger (if your printer is connected) when the scan is finished. This feature appears on the Internal View page when 2D View is enabled and when Industrial Series is selected from the Printer Type drop-down on the Part View page. For more information, see Insert a Laser Scan after a Layer.

Start Rotation Percentage: The point along the perimeter of the part at which the fiber path for the Concentric Fiber Rings will start. Start Rotation Percentage for the first fiber layer should default to 11% and should increase by 2%-3% over subsequent fiber layers. Having varying Start Rotation Percentage angles prevents seams or gaps in fiber. Entering a value for the Start Rotation Percentage when 3D View is enabled will set that value across all layers in the group. This feature appears on the Internal View page when Use Fiber is enabled.

STL files: The standard file type used by all additive manufacturing systems. STL files are exported by CAD and 3D modeling programs as a simplified mesh of only surface geometry. STL files lack metadata relating to CAD or the originating program.

Supports Angle field: Enter a value between 0 (parallel to X-axis, default) and 90 (parallel to Y-axis) to modify the angle, in degrees, at which your supports will print -- not the overhang angle, but rather the direction of the support lines relative to the print bed. This feature appears on the Part View page when Use Supports is enabled.

Total Fiber Layers slider: Set the number of fiber layers to print inside your part. The number you set will be the total number of layers, with half of them generating at the top of your part and the other half generating at the bottom. This feature is located on the Part View page.

Use Brim: Print a thin layer of support material anchoring your part to the print bed. This feature is meant to be used if your part has few points of contact on the print bed or tends to warp during printing. The brim will automatically generate around the outer walls of the part's first few layers when this feature is enabled. This feature is located on the Part View page.

Use Fiber: Enable fiber reinforcement for the selected layer(s) of the current part. Fiber will automatically generate as a sandwich panel with six total layers. This feature is located in the Editing Layers box on the Internal View page. For more information, see Adding Fiber.
Note: Use the Reinforcement Material drop-down on the Part View page to select a specific fiber type.

Use Supports: Print columns of plastic beneath overhanging features of the part to maintain stability during printing. Nylon parts usually require supports for angles that are less than 70 degrees from horizontal; Onyx parts usually require supports for angles that are less than 45 degrees from horizontal. This feature is located on the Part View page. For more information, see Supports and 3D Printing.

Visibility: Show or hide different tool paths in your part for better visibility of features. This feature is located on the Internal View page.

Wall Layers slider: Select how thick the walls of the part should be. More walls will make a plastic part stronger but will also reduce the area that fiber will be able to fit into; for metal parts, more walls will make a part stronger and provide additional tolerance for machining, but will also increase print and wash times. Using fewer than two walls, especially on parts with fiber, will generally result in poor surface finish on your part. This feature is located on the Part View page.

Walls to Reinforce: Select one of the following options. This feature appears on the Part View and Internal View pages when Concentric Fiber is selected from the Fiber Fill Type drop-down.

  • Outer Shell Only: Adds concentric rings to reinforce the outer perimeter of the part. This gives the part strength in bending around the Z axis by reinforcing the walls with parallel strands of fiber.

  • Inner Holes Only: Adds concentric rings around all internal features of the part. It is an easy and material-efficient method to reinforce holes, cavities, and any other internal features.

  • All Walls: Adds the specified number of concentric rings to both the perimeter of the part and all internal features. This default setting combines the reinforcement strength of both Outer Shell and Inner Hole reinforcement.
