Learn how to convert STL to GLB with CAD Exchanger

STL

STL (STereoLithography) is a file format native to the stereolithography CAD software. This file format is supported by many other software packages; it is widely used for rapid prototyping, 3D printing and computer-aided manufacturing. STL files describe only the surface geometry of a three-dimensional object without any representation of color, texture or other common CAD model attributes. The STL format specifies both ASCII and binary representations. Binary files are more common, since they are more compact.

GLB

GLB is a standardized file format for sharing 3D data used in virtual reality, augmented reality, games, and online applications. GLB files are a binary form of the GL Transmission Format (glTF) file, which employs JSON (JavaScript Object Notation) encoding.

Supporting data such as 3D scenes, models, lighting, materials, and geometry / animation are all stored in a single GLB file, eliminating the need for extra support files to access textures, geometry, shaders, animation, and other types of data required for a 3D view. GLB files are 30% smaller than glTF and its associated files, so they load and process faster.

GLB is compatible with various 3D visualization programs, such as Microsoft Paint 3D, Microsoft Remix 3D, Blender, Trimble 3D Warehouse, SketchUp.

Frequently Asked Questions

What are the benefits of converting STL to GLB in CAD Exchanger?

CAD Exchanger Lab is an easy-to-use 3D viewer and converter to read and write 30+ key 3D formats. It allows you to view and convert files, measure objects, build sectioning views, explode assemblies, create meshes and view PMI.

High-performance visualization, precise geometry, B-Rep modeling, turning individual assemblies and parts on and off make CAD Exchanger a useful tool for all facets of a design project.

Is there an SDK to build a STL to GLB conversion feature in my own application?

Software libraries to read, write and visualize 3D CAD files, including GLB and STL, are available in CAD Exchanger SDK, a set of C++ / C# / Java / Python libraries to develop fast and robust 3D applications.

Is there an option to batch convert STL to GLB files in CAD Exchanger?

Batch conversion feature is available in CAD Exchanger Batch (Command Line Interface), a light-weight server-based solution for batch conversions of CAD data in corporate or cloud environments.

How are CAD Exchanger products licensed?

For CAD Exchanger Lab, there are two licensing models – perpetual and subscription – which differ in access duration, either perpetual or for 12 months.

There are individual seat licenses which are per user, per seat (and are linked to a fixed MAC address), and team licenses which enable group access, either on a server or within a network domain.

Any license includes access to all formats and all features.

Subscription includes access to all releases within the subscription period. To get access to new versions under the perpetual license, annual maintenance must be purchased additionally.

Everything you need to know about CAD file formats

A CAD file is an output of a CAD software, containing key information about the designed object: its geometry and topology representation, 3D model hierarchy, metadata, and visual attributes depending on the format of the file.
