The most popular biofoam in the use of biomedical devices is PLA as well. PLA's properties are also desirable in biomedical applications, especially in combination with other polymers. Specifically, its biocompatibility and biodegradability make it favorable in tissue engineering through the use of FDM-3D printing. PLA does well in these printing environments as its glass transition temperature as well as shape memory is small. In recent studies, PLA has been specifically combined with hydroxyapatite (HA) in order to make the modulus of the sample more favorable for its application in repairing bone failure. Specifically in tissue engineering, HA has also been shown to generate osteogenesis by triggering osteoblasts and pre-osteoblastic cells. HA is a strong material, which makes it ideal to add to PLA, due to the fact that PLA has weak toughness with a 10% elongation before failure. FFF-based 3D printing was used as well as compression tests demonstrated in Figure 5. The results showed that there was a self-healing capability of the sample, which could be used in certain biomedical practices.
