Figure 3. Fabrication and characterization of IVRs by unit cell design and band presence.

Figure 3.

IVRs from group (3) were designed by varying unit cell design, holding unit cell size constant at 3.80 mm with band parameters of 4.0 mm height (H) and 0.6 mm thickness (T). (A) Whole banded DLS fabricated rings are shown in SIL 30 with inlays of internal architecture by CAD, in UMA, and in SIL 30. Fabricated rings were imaged with stereo microscopy. (B) Dimensional analysis of outer diameter, cross-sectional diameter and wall thickness. Outer and cross-sectional diameter measurements represent average and standard deviations of n=4 per ring type. Wall thickness values represent average and standard deviation of n=4 per sample and n=4 per ring type (total of 16). Percent deviation from theoretical values is shown italicized. (C) Load at 50% compression (N) as a function of unit cell type, band presence and force orientation. Values represent average and standard deviation of n=4 per ring type.
