以氧化锆粉为主要原料,采用基于螺杆挤出的熔融沉积法在4种打印路径(单线、网格、单线+矩形、网格+矩形)下3D打印制备了孔隙率均分别为15%、25%、35%、45%的多孔氧化锆陶瓷。对多孔陶瓷的孔壁、打印层间结合、孔结构等...展开更多 以氧化锆粉为主要原料,采用基于螺杆挤出的熔融沉积法在4种打印路径(单线、网格、单线+矩形、网格+矩形)下3D打印制备了孔隙率均分别为15%、25%、35%、45%的多孔氧化锆陶瓷。对多孔陶瓷的孔壁、打印层间结合、孔结构等进行了显微结构分析,并检测压缩强度。结果表明:1)采用熔融沉积法可以3D打印制备孔壁结构致密、孔形状保持良好的多孔陶瓷;2)低孔隙率时,多孔氧化锆陶...

Porous zirconia ceramics with the porosity of 15%,25%,35% and 45% were prepared by 3D printing in four printing paths(single line,grid,single line+rectangle,and grid+rectangle)using zirconia as the main raw material and the fused deposition modeling method based on scre...MORE Porous zirconia ceramics with the porosity of 15%,25%,35% and 45% were prepared by 3D printing in four printing paths(single line,grid,single line+rectangle,and grid+rectangle)using zirconia as the main raw material and the fused deposition modeling method based on screw extrusion.The microstructure of the pore wall,the ...
