12 GuidesThe Complete Guide to STL Files
Everything you need to know about the STL format — from binary vs ASCII internals to repair workflows, 3D printing optimisation, and conversion to GLB, OBJ, and FBX. 8,000+ words.
What Is an STL File?
The definitive intro to STL — what it stores, what it can't, and why every 3D printer on earth uses it.
Binary vs ASCII STL — What's the Difference?
Most people have no idea STL has two formats. One is human-readable, the other is 6× smaller. Here's when to use each.
What Is a GLB File?
GLB is glTF in a single binary package — the format that powers AR, game engines, and the web. What's inside, and why it wins.
How STL Converts to GLB — And Why Colors Disappear
STL has no material data. When you convert, colors are gone. This guide explains exactly why — and what to do about it.
GLB vs glTF — Which Should You Use?
Same spec, different packaging. GLB is one file; glTF is a folder. Here's the practical difference for web, game dev, and AR.
Best Slicer Software for 3D Printing in 2026
Cura, PrusaSlicer, Bambu Studio, Chitubox — compared side by side. What to use for FDM vs resin, beginner vs advanced.
How to Repair Broken STL Files
Non-manifold geometry, holes, and inverted normals crash slicers. Here's how to diagnose and fix every common STL error.
STL vs 3MF — Should You Switch?
3MF stores color, materials, and print settings in one file. STL stores only geometry. For 3D printing in 2026, the answer is clear.
Why STL Has No Bones, UV Maps, or Animation
A deep dive into STL's design philosophy — and why it deliberately stores only triangle meshes, nothing else.
