Figure 4. Mechanical Characterization of 3DP-PDMS.

Figure 4.

(a) 3D printed flexible dog-bone structure made with 3DP-PDMS. (b) Representative stress-strain curves of dog-bone specimens printed with 3DP-PDMS prepared with different ratios of end group and side-chain macromers. (c) Young’s modulus of 3DP-PDMS prepared with different ratios of end group and side-chain macromers. Error bars are SEM. (d) Elongation at break values of 3DP-PDMS prepared with different ratios of end group and side-chain macromers and different photoinitiator concentrations. Error bars are standard deviations. The elongation-at-break of Sylgard-184 PDMS is shown as a dotted line.
