A user prints parts, scans them and compares against the STEP. "The colour map shows exactly where the print warped or shrank... But that's where it ends." Today the fix is "editing the CAD by hand and guessing from the colour map," and the tools that do proper distortion compensation "are expensive commercial packages." The ask is a compensated mesh export, with a pinned bed face and a strength setting. Measured data that never flows back into the model. A first-person workaround with a clear price gap.
