Figure 1. (A) Replacement of line matrix in the nasal region of the previously developed facial mask with the curve matrix; (B) Five deformation mechanisms designed by stacking PLA and SMP, showing top view, cross-section, naming, and thicknesses; (C) Definition of connecting frame size, rib end points (L0 = 12 mm), and sweep angle (θ0 = 30°-160°). PLA: Polylactic acid; SMP: shape memory polymer.
