Fabrication Scaffold by Extrusion Freeforming from High Solid Loading Ceramic Paste
A method for fabrication of mineral materials was studied. Micro extrusion freeforming of ceramics from high solid loading ceramic paste has advantages of low shrinkage stress, high sinter density, and environmental friendliness. Hydroxyapatite and alumina lattices were directly fabricated using 80 microns to 500 microns filaments. We report here on the implementation of design and fabrication of these scaffolds for photonic band gap materials. Influence of the solid contents of paste in the process of extrusion freeforming was studied.
