Every new account receives 10 free trial credits automatically on signup. One credit equals one STL processed successfully. Trial credits don't expire while your account is active.

From the Dashboard click "Upload ZIP", drag your archive into the dropzone (max 2 GB), wait for the preflight summary, then click "Process now" to spend credits. Results are ready under "History".

Each STL must have a sibling PTS with the exact same base name. For example, case_001.stl pairs with case_001.pts. Files that don't pair are flagged in the preflight summary and are ignored.

The current limit is 2 GB per ZIP. If your batch is larger, split it into multiple ZIPs and queue them sequentially.

We accept ZIP archives only. Re-export your batch as a single .zip file and try again. Compressed formats like 7z, rar or tar.gz are not currently supported.
