Choose GLB for the web
Keeps color and materials; compact and ideal for browser display.
Decision中文
STP to GLB or STL?
Both GLB and STL are common STEP/STP conversion targets, but they serve different goals. The right choice depends on whether you need color and web-friendliness, or a clean printable mesh.

Choose STL for printing
Geometry-only triangle mesh, the standard for 3D printing.
Consider both
Export GLB for review and STL for the print job from the same source.
When GLB is the better pick
GLB (binary glTF) carries color, materials and scene data in a single, web-optimized file.
It is the right choice for online viewers, product configurators, AR/VR and visual review.
When STL is the better pick
STL stores only the surface mesh, which is exactly what slicers expect for 3D printing.
If your end goal is a printed part, STL avoids unnecessary data — just remember it carries no color.
FAQ
Does GLB keep color?
Yes. GLB preserves color and materials, unlike STL.
Is STL good for the web?
It can be displayed, but it lacks color and is less efficient than GLB for visual delivery.
Can I get both from one STP file?
Yes. Convert the same STP to GLB for review and STL for printing.
