“…Different pure or chemically modified synthetic polymers have already been used for tissue engineering applications, such as polycaprolactone for bone (Fedore, Tse, Nam, Barton, & Hatch, ; Groppo et al, ; Xue et al, ) or acrylonitrile butadiene styrene for tendon (Mozdzen, Rodgers, Banks, Bailey, & Harley, ) and skin (Cai, Azangwe, & Shepherd, ) tissue repair. Poly(lactic acid) (PLA) is another frequently used polymer for vascular (Tung, Chang, Ju, & Wang, ), cartilage (Revati et al, ; Su, Chen, Chen, & Chen, ), or bone (Du et al, ; Hao, Jiang, Jiang, Wang, & Wang, ; Lu, Dong, Zhang, Liu, & Wang, ; Zhao et al, ) applications. It displays favorable printing properties such as a low glass transition temperature (50–60°C) and it does not require a heated printing bed.…”
