## What is Vattrace?

Vattrace is an offline calibration and maintenance ledger for resin-printing users who need profiles to stay tied to real conditions.

Build a private profile lineage for every printer, resin, layer height, temperature, calibration coupon, vat, and outcome.

KEY FEATURES
- Printer, resin, lot, color, and layer profile matrix
- Exposure-ladder comparison history
- Layer-count and core-time estimator
- Vat film and screen service timeline
- Failure evidence and controlled-change notes
- PDF profile and maintenance brief
- Optional local photos through Apple's Photos picker
- Local PDF project brief
- 230 original offline reference plates
- No account, ads, analytics, tracking, subscription, or network requirement

Vattrace records user-entered printer settings and estimates. It does not slice files, control printers, certify materials, assess ventilation or chemical exposure, or replace resin safety data, manufacturer instructions, PPE, and responsible handling.
