Paper: Thingi10K: A Dataset of 10,000 3D-Printing Models / Mesh Arrangements for Solid Geometry

About

Thingi10K is a dataset of 3D-Printing Models. Specifically there are 10,000 models from featured “things” on thingiverse.com, suitable for testing 3D printing techniques such as structural analysis , shape optimization, or solid geometry operations.

In a nutshell, Thingi10K containsthe following.

• 10,000 models
• 4,892 tags
• 2,011 things
• 1,083 designers
• 72 categories
• 10 open source licenses
• 7+ years span
• 99.6% .stl files
• 50% non-solid
• 45% with self-intersections
• 31% with coplanar self-intersections
• 26% with multiple components
• 22% non-manifold
• 16% with degenerate faces
• 14% non-PWN
• 11% topologically open
• 10% non-oriented

Dataset Summary

Total number of files: 10,000

• STL files: 9956
• OBJ files: 42
• PLY files: 1
• OFF files: 1

Errors

The following models are known to be "corrupt." However, they are still included in the dataset in order to faithfully reflect mesh qualities on Thingiverse.

• Model 49911 is truncated (ASCII STL).
• Model 74463 is empty.
• Model 286163 is empty.
• Model 81313 contains NURBS curves and surfaces instead of polygonal faces, which may not be supported by many OBJ parsers.
• Model 77942 is corrupt (binary STL). Here is a potential replacement model created by a different user.
