Add Blind Watermark to STL using Java library without any 3D modeling software.

How to Watermark to STL File Using Java

In order to watermark STL file, we’ll use

Aspose.3D for Java

API which is a feature-rich, powerful and easy to use watermark API for Java platform. You can download its latest version directly from

Aspose Maven Repository

and install it within your Maven-based project by adding the following configurations to the pom.xml.


<name>Aspose Java API</name>


<version>version of aspose-3d API</version>

Steps to Add Blind Watermark to STL via Java

Java programmers can easily add blind watermark to STL in just a few lines of code.

  • Load STL file via the constructor of Scene class
  • Get the mesh class of Aspose.3D
  • Add watermark and password using Aspose.3D’s EncodeWatermark method
  • Call the Scene.Save method with object

System Requirements

Aspose.3D for JAVA is supported on all major operating systems. Just make sure that you have the following prerequisites.

  • Microsoft Windows or a compatible OS with Java Runtime Environment for JSP/JSF Application and Desktop Applications.
  • Get latest version of Aspose.3D for Java directly from Maven.

JAVA code to Add Blind Watermark to STL

//The source file that needs to be watermarked and the output file after saving
String file = "template.stl";
String output = "outFile.fbx";

// create an instance of Scene
Scene scene = new Scene(file);

//Add watermark and password to files
AtomicInteger numMeshes = new AtomicInteger();
scene.getRootNode().accept((Node node)->
    Entity mesh =node.getEntity();
    if (mesh != null)
        try {
            mesh = com.aspose.threed.Watermark.encodeWatermark((Mesh)mesh, "HelloWorld", "1234");
        } catch (IOException e) {
        if (mesh != null)
            node.setEntity((Entity) mesh);
    return true;

//Save the file in the format you want, FileFormat.FBX7400ASCII);
