| 초록 | In this study, we were manufacturing the three dimensional tubular structure by UV polymerization in fine scale with dual nozzle which consist of core-shell syringe. Significant differences in conventional method such as precipitation and gelation technique, It can be manufacture complex shape and free standing structure because of their in situ fast solidification and high shape retention ability. For core and shell materials, carbon paste and ceramic slurries were developed, respectively. The ceramic slurries composed ceramic powder, photocurable acrylate monomers and photo-initiator, dispersant. Simultaneously, the co-extrusion process was also studied by controlling the slurries viscosity and extrusion pressure, as a result we could successfully fabricate to uniform green body tubular structure. After subsequent sintering process in air at high temperature, in which the carbon core was burnout clearly, shell structure formed of predetermined wall shape and thickness were manufactured. This new concepts allows for the formation of highly porous complex shape structure such as DDS(drug delivery system) scaffold and bone regeneration with increase the surface area. |
