This may be a case of redefinition. In the July 1988 version of the Stereolithography Interface Specification, there is no mention of
what the STL actually stands for.

It only says: 'These files are also called "STL" files because
they are typically given a file extension of .STL.'

So take it from there!

Dear Yasuo,

The "Stereo Lithography Interface Specification" as published by 3D Systems in Oct 1989 mentions:

"... These triangle files are also called "STL" for StereoLithography files and they are typically given the file extension of .STL ..."

Best Regards,

Lex Lennings.
