Porous (polyamide/hydroxyapatite) composites were manufactured via SLS (selective laser sintering) process. Specimens with different PA2200/HA contents (100/0; 95/5; 90/10 and 80/20) were sintered at relative low laser energy density. The porous composite specimens were characterized for dynamic-mechanical analysis. The dynamic-mechanical properties changed as a function of the composition of the composite materials. Storage and loss modulus vary from 1,050 to 215 MPa and 35 to 5 MPa, respectively.
