Figure 5.

Mechanical effects of varying environmental temperature. (a) Stress–strain curves of tensile specimens tested longitudinally; (b) ultimate tensile strengths of longitudinal specimens printed with different environmental temperatures. The reference value of unprinted bulk polycarbonate (PC) is denoted as the pale blue shaded region; (c) stress–strain curves of tensile specimens tested transversely; (d) ultimate tensile strengths of transverse specimens printed with different environmental temperatures. The error bars are from standard deviations of data obtained from five measurements. The reference value of unprinted bulk PC is denoted as the pale blue shaded region.
