Reshapability of 3D printing reprocessable thermosets. a–c Dynamic mechanical analysis (DMA) tests to investigate the effect of thermal treatment on mechanical properties of samples printed with reprocessable thermosets. d Uniaxial tensile tests of printed samples before and after the 4 h thermal treatment at 180 °C. Demonstration of stiffness change of a printed Kelvin foam (e), before (f), and after (g) thermal treatment (TT) at 160 °C for 12 h. h Demonstration of combining 3D printing with traditional thermoforming to expand capability and reduce time of manufacturing.
