Fig. 9. 3D piece of the polyamide structured by RP.

Bioactivity tests in SBF and fibroblast cell cultures were performed. There was growth of
differentiated cells in the fibroblast culture for both functionalized polyamide and ABS.
Figures 10 a, b, c, and d correspond to the results obtained with polyamide 12 without and
with coating and ABS without and with coating after 4 days, respectively. It was possible to
observe that the cells were not affected by the coating, showing that the materials present
potential future applications for use in biomaterials.
