New Hatching Strategy Example

Step 1: Import

  • Start the application "GENESIS-hatching.exe".
  • While you are in the "Import" step click the uppermost "Open" button in the "Model / Part" section on the right side.
  • Select the STL-file Connector.stl and click "Open".
  • Proceed to the next step by pushing the "Preset" button in the top bar.

GENESIS Tutorial Import Step 1: Open the Demo-Part.stl.

Step 2: Preset

  • Select the "Default" settings from the "Printer Preset".
  • Choose a "Layer Thickness" of $d = 0.9$ mm.
  • Proceed to the next step by pushing the "Part" button in the top bar.

GENESIS Tutorial Preset Step 2: Default preset and 0.9 mm layer thickness.

Step 3: Part

The slices will be calculated in the background. One can continue with the selection of parameters without any problems. After all layers have been calculated one can optionally investigate the slices with the slider on the right side of the viewer.

  • Select the "Hexagon-based" hatching from the "Simulation-based" Strategies for the Part section (second row, indicated by "Sim.") in the top region of the properties inspector pane.
  • Change the "Hatch Distance" to 1.8 for generating the fill hatchings with a distance of 1.8 between each other.
  • Choose "Bidirectional Hatches" by clicking the check box for alternating the direction of the following path.
  • Leave "Layer Rotation" on the default value of 137.5 for having a rotation of the following layer of the golden angle.
  • Leave "Start Angle" on the default value of 0 for starting with a layer orientation of 0 degrees.
  • Choose a "Number of Contours" of 2 with the following contour settings for getting 2 contour paths:
  • The "Contour Offset" should be 0.9 for having a small distance between the part outline and the outermost contour scan.
  • Set the "Contour Distance" to 0.6 for the distance between each contour scan.
  • Set the "Contour to Hatch Dist." to 0.3 for having a small gap between the innermost contour scan and the filling hatches.
  • Leave the "Island Distance" on the default value of 0 for generating the individual hexagons close to each other
  • Change the "Island Size" to 10 for generating medium sized hexagon islands and allowing them to orientate quite often.
  • Leave the "Random Order" unchecked.
  • Start the simulation by clicking the "Hatching" button in the top bar.

GENESIS Tutorial Part Step 3: Simulation-based hexagon part hatching.

Step 4: Support

If the part does not need a separate support structure and no file was specified before (like in this case), just skip this step.

Step 5: Hatching

The hatchings will be generated in the background. Because of the selected hexagon-based hatching strategy, the part will be simulated before the hatchings can be shown. Depending on the computing power of the machine this will take a while (approximately 3 to 10 minutes).

  • The progress bar shows the actual progress of the simulation and generation process.
  • Export the generated hatchings by pushing the "Export CLI" button in the lower right area and choose a proper file name and location from the file dialog.
