This note distinguishes chemical shrinkage from residual stress and geometry-dependent warpage. Three topical sources support curing-dependent thermoviscoelastic behaviour, grayscale dose-gradient modelling and digital warpage compensation. ISO 291:2008 is identified for conditioning atmosphere, while the exact dimensional, thermal and mechanical methods must be selected for the intended claim. The document is not a quantitative meta-analysis and does not pool values across formulations, machines or geometries. RP-02 defines the shared qualification method.
