About us
SENTINEL exists because the choice on the table — unregulated printers or heavy-handed surveillance — is a false one. We're building the third option: safety enforced on the device, privacy preserved by architecture.
Our story
SENTINEL grew out of FabraForma LLP, a 3D-printing service bureau in Mumbai. Running a production fleet means seeing thousands of customer files a year — and understanding, concretely, both how much good this technology does and how it can be abused.
When California introduced AB 2047, the industry's reaction split between denial and dread. We saw something else: a solvable engineering problem. Manufacturers shouldn't each have to build a DOJ-grade detection algorithm from scratch, and makers shouldn't have to surrender their designs to the cloud to stay legal.
So we built the layer we'd want on our own machines — accurate enough to certify, private enough to trust.

The company
What we believe
If blocking depends on a server, it fails offline and invites surveillance. Real protection lives in the firmware, works in airplane mode, and can't be routed around.
Makers' designs are their IP and their business. SENTINEL never uploads, harvests, or fingerprints-for-marketing anyone's files. We screen; we don't watch.
Detection systems are measured in false positives and false negatives, and we publish our thinking about both. No security theater — for regulators or for customers.
We're talking with printer manufacturers, investors, and policy teams. If that's you, we'd like to hear from you.
