本研究所使用之線材為硼矽酸玻璃粉末摻合聚乳酸(PLA)之複合材料(Pyrex Borosilicate Glass Filament™)，其組合質量比例為玻璃粉末73 %及聚乳酸27 %，線材密度為1.5g / cc。使用繪圖軟體(SolidWorks)繪製所需測試零件設計圖，轉存成STL文件，載入3D列印機（Ultimaker2+）製出所要使用的零件，再放入高溫燒結爐加熱，燒結過程使零件內聚乳酸成分裂解，進而提煉出純粹硼矽酸玻璃，再進行各項實驗測試，實驗分成兩大項，分別為表面形貌觀察及機械性質測量差異。藉由觀察燒結前後零件特性變化，就表面型態及機械性質量測比較，包含SEM觀測、EDS分析、燒結前後物體外觀改變、熱性能、硬度、耐磨耗等。從實驗結果得知，本製程玻璃零件經過燒結後，組合成分改變，其導熱性、熱擴散性及耐磨耗等性能均獲得明顯提升，並且在製作過程中，因為零件長時間置於高溫環境中，導致玻璃內部方石英晶體成核，使其熱及機械性能優於傳統製程手藝成品。此製作過程不同於利用傳統玻璃窯製手藝，需經過配料、熔製、成型、退火及整修等五個步驟煉製，製造過程簡單、成本低廉，能以低成本及高效率過程來取得玻璃零件有效地減輕市面上繁雜玻璃製程及高額成本問題，達到最高的效益。

In this research, the filament is a composite material of borosilicate glass powder mixed with polylactic acid (PLA). The combined mass ratio is 73% glass powder and 27% polylactic acid, and the filament density is 1.5g /cc. The production process is to use a 3D printing machine to produce the accessories to be used, and then put them into a high-temperature sintering furnace for heating. The sintering process cracks the polylactic acid component in the filament to extract pure borosilicate glass, and then conducts various experimental tests. The two major items are the surface morphology observation and the difference in mechanical properties measurement. By observing the changes in the characteristics of parts before and after sintering, the surface morphology and mechanical quality are measured and compared, including SEM observation, EDS analysis, object expansion and mass change before and after sintering, thermal conductivity, specific heat, hardness, wear resistance, etc. It can be seen from the experimental results that after the parts are sintered in this process, the composition of the parts is changed, and their thermal conductivity, thermal diffusivity and wear resistance are significantly improved. During the production process, the parts are placed in a high temperature environment for a long time, which leads to the nucleation of cristobalite crystals inside the glass, making its thermal and mechanical properties superior to those of traditional craft products.
