FAQ

ETS to STL Conversion

What are ETS files?

ETS files are used in virtual microscopy to store the full-resolution image data captured from digital slides. Commonly generated by Olympus slide scanners, ETS files work alongside VSI (Virtual Slide Image) files to enable detailed, zoomable viewing of high-resolution microscope images. An ETS file contains the raw image tiles that make up the actual slide content, allowing for fast, fluid navigation across large specimens in digital pathology and biomedical research.

What are STL files?

STL is the proprietary format for a computer-aided design (CAD) program developed by 3D Systems. STL is an acronym for Stereolitography, which is a type of technology used for creating prototypes or patterns through 3D printing. An STL file contains a surface representation of such a model, without detailed specifications of aspects such as colours. STL files can only be opened with a limited number of programs.
