Convert FBX to STL via Java

FBX to STL conversion using Java library without any 3D modeling software.

How to Convert FBX to STL Using Java

In order to render FBX to STL, we’ll use

Aspose.3D for Java

API which is a feature-rich, powerful and easy to use conversion 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 Convert FBX to STL via Java

Java programmers can easily convert FBX file to STL in just a few lines of code.

  1. Load FBX file via the constructor of Scene class
  2. Create an instance of StlSaveOptions
  3. Set STL specific properties for advanced conversion
  4. Call method
  5. Pass the output path with STL file extension & object of StlSaveOptions

System Requirements

Before running the Java conversion code, 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 3D Scene Manipulation Library

    Aspose.3D is a CAD and Gameware API to load, modify and convert 3D files. API is a standalone and does not require any any 3D modeling or rendering software. One can easily use API for Discreet3DS, WavefrontOBJ, STL (ASCII, Binary), Universal3D, FBX (ASCII, Binary), Collada, glTF, PLY, GLB, DirectX and more formats.

    FBX What is FBX File Format

    FBX, FilmBox, is a popular 3D file format that was originally developed by Kaydara for MotionBuilder. It was acquired by Autodesk Inc in 2006 and is now one of the main 3D exchange formats as used by many 3D tools. FBX is available in both binary and ASCII file format. The format was established to provided interoperability between digital content creation applications. There are many tools available for conversion from/to FBX file format.

    STL What is STL File Format

    STL, abbreviation for stereolithrography, is an interchangeable file format that represents 3-dimensional surface geometry. The file format finds its usage in several fields such as rapid prototyping, 3D printing and computer-aided manufacturing. It represents a surface as a series of small triangles, known as facets, where each facet is described by a perpendicular direction and three points representing the vertices of the triangle. Resultant data is used by applications to determine the cross section of the 3D shape to be built by the fabber. There is no information available in the STL file format for representation of colour, texture or other common CAD model attributes.
