Powerful STL compression software

Compress STL data by more than 80% – free!

Stomp that STL

Whether your STL data is 100 MB or 10 MB, Stomp provides a simple interface for STL file compression. Once your STL file has been compressed to an STM file you can share this quickly via email and the recipient can un-Stomp using Stomp or load directly into Composer.

Download Stomp for free.

STL file viewer

No CAD program? No problem.

Share STL data with clients for review prior to printing. Your clients can now view the STL file in a simple interface allowing them to zoom, rotate and pan around the STL data.

Simple editing tools

All in a simple interface.

Scale, mirror, rotate or position the downward facing surface accurately, Stomp provides a basic set of tools for simple file manipulation.

Export slice data

Convert STL to SLC

For CAM systems that require SLC data for printing, Stomp can take an STL file and convert it into an SLC file.

Use Asiga Sleece for viewing SLC files.
