AUTHENTICITY CHECK

Is it really made with Kiln?

Drop an STL, 3MF, or assembly-manual PDF. We'll check Kiln's signature and tell you what it is — made, modified, or processed with Kiln, by whom — and whether the exact bytes are untouched.

For an .stl or .3mf made with Kiln, just drop the file — the proof is inside, no ID needed. The Release ID field is only for verifying an assembly-manual PDF; for a Kiln-augmented .3mf manual it's auto-detected, and otherwise it's on the kit-maker's listing or the print's QR code.
