对立体光刻法制备的管状单通道氧化铝膜的形貌设计进行了初步研究。使用计算流体动力学计算优化膜的环形图案内表面的几何形状，并在铜绿假单胞菌的水性悬浮液的微滤测试中进行验证。管状膜的内表面的图案化有助于在较高的平均错流速度值下减少滤饼的形成。结果突出了立体光刻为基础的方法的陶瓷膜的形态设计的好处。
A preliminary study was carried out on the morphological design of tubular single-channel alumina membranes prepared by stereolithography, an additive manufacturing process. The geometry of the ring-patterned inner surface of membranes was optimized using computational fluid dynamics calculations and validated in microfiltration tests with aqueous suspensions of P. aeruginosa. Patterning of the inner surface of tubular membranes helped reduce cake formation at a higher value of the average crossflow velocity. The results highlight benefits of stereolithography-based approach to the morphological design of ceramic membranes.
