What is STL?
Stereolithography – STL ist das Standardformat fuer 3D-Druck. Es beschreibt die Oberflaeche eines Modells als Dreiecksnetz ohne Farb- oder Materialinformationen. Jeder 3D-Drucker und Slicer unterstuetzt STL.
Common use cases: 3D-Druck (FDM, SLA, SLS), Rapid Prototyping, CNC.
What is GLB?
GL Binary Transmission Format – GLB ist das binaere Container-Format fuer glTF und speichert 3D-Modelle mit Texturen, Materialien und Animationen in einer einzigen Datei. Es ist der Standard fuer Web-3D, AR/VR und Echtzeit-Anwendungen.
Common use cases: Web-3D, AR/VR, Echtzeit-Visualisierung, Social Media 3D.
Why Convert STL to GLB?
Converting from STL to GLB is useful when you need to move models between different software ecosystems. For example, STL files from one workflow may need to be opened in tools that only support GLB, or you may need GLB for 3D printing, web publishing or AR applications.
