| Summary: | 碩士 === 國立臺北科技大學 === 製造科技研究所 === 107 === Low-temperature deposition manufacturing(LDM) is only one method of bioprinting that fabricates bioscaffold using Polymer biomaterial solution. LDM technology's feature is its pore structures of scaffolds, which is advantageous in cell culture. Unfortunately, the feature declines mechanical properties of the scaffolds. LDM technology is not suitable for fabricating scaffolds of higher mechanical strength requirements. Therefore, the Development of a bioprinter for fabricating bioscaffold of solid fiber using Polymer biomaterial solution will be proposed in this research. The process fabricates bioscaffolds with solid fiber; through the process of which solvent evaporation reduces the volume of the material.
The system proposed consists of four modules which allows the produced objects a maximum build volume of 200mm×200mm×100mm. The first module is in charge of moving the nozzle in the XYZ direction, while the second and third controls the temperature of the material and build platform, respectively. The last module adjusts the airflow that controls the evaporation of the solvent of material. Finally, diverse 3D models with different structures were fabricated in order to inspect the performance of the bioprinter.
