Three-dimensional bioactive and biodegradable scaffolds fabricated by surface-selective laser sintering

Surface-selective laser sintering (SSLS) has been developed for fabrication of three-dimensional polymer composite scaffolds with precise dimensions and intricate structure (see Figure), which are bioactive and biodegradable. SSLS allows sintering of polymer powders by melting only the surface layers of particles, which prevents overheating of internal domains, allowing incorporation of bioactive molecules into the structures.
