What is a .stl file?

STL (Stereolithography) is a 3D model format that represents a surface as an unstructured collection of triangular facets, each with a normal and three vertices. It stores only geometry with no color, texture, or units, and comes in ASCII and binary variants. It is the workhorse format for 3D printing.

How to use this file

Use an example STL to test mesh loaders, ASCII versus binary parsing, slicer and 3D-print pipelines, and geometry validation such as watertightness checks.

How to use this file for testing

“STL — ASCII Pyramid SAMPLE” is a deterministic Novus Examples fixture for Conversion testing. The same content exported across many formats and linked as a group, so you can convert one and diff against the expected twin.

Documented properties for this file: ASCII. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.

Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.

3D and CAD fixtures carry one small, documented solid or scene. Convert and inspect against the known geometry, units, and structure; format twins let you diff interchange fidelity, and the 3D viewer previews the actual mesh.

Code examples

import trimesh  # pip install trimesh

mesh = trimesh.load("pyramid.stl")
print(mesh.bounds, mesh.faces.shape)
