​
Objective:

Learn how to slice an implicit body into an image stack for additive manufacturing printers that accept images.

​
Applies to:

  • Additive Manufacturing
  • Slices for Open DLP and Binderjet systems

​
Procedure:

1. Prepare the part
  • Convert the part into an Implicit body
2. Choose a Build Volume
  • If you are printing from an EOS M or Renishaw AM machine, you can choose from built-in Build Volume blocks.
  • If your machine isn’t one of these, create your build volume with a Bounding Box block
3. Orient the part within the Build Volume 4. Slice the part
  • Add a Slice Body to B&W Image Stack block
  • Path: Choose the destination to save the slices
  • Fill Suffix:
  • Toggled On: Names the files: “slice_001”, where the number of 0’s before the slice number is determined by the total number of slices.
  • Toggled Off: The files are named “slice_1”, with no 0’s.
  • Body: Insert the Implicit Body you want to slice.
  • Layer Height: Define the spacing between the layers. You may need to check the printer settings for the appropriate range of heights.
  • Frame: This is the coordinate system for the build plate. It is auto-populated but may need to be edited depending on the printer settings.
  • Print Volume: Insert the Bounding Box or Build Volume from Step 2.
  • The resolution is the number of pixels in the X and Y directions. This value may change depending on your printer and desired resolution. The maximum image resolution supported is 1 billion pixels.
  • Image X resolution: 1920
  • Image Y resolution: 1280
  • Greyscale bits: 8 bits
The visualized implicit body to be sliced using the Slice Body to B&W Stack. After all the inputs are filled, the block saves the resulting .png file format image stack in the zip folder defined earlier. A gif showing the B&W images that are exported from nTop. And that’s it! You’ve successfully learned how to generate a B&W Image stack for manufacturing. Are you still having issues? Contact the support team, and we’ll be happy to help!
