Transparent stereolithographic rapid prototyping (RP) technology has already demonstrated in literature to be a practical model construction tool for optical flow measurements such as digital particle image velocimetry (DPIV), laser doppler velocimetry (LDV), and flow visualization. Here, we employ recently available transparent RP resins and eliminate time-consuming casting and chemical curing steps from the traditional approach. This note details our methodology with relevant material properties and highlights its advantages. Stereolithographic model printing with our procedure is now a direct single-step process, enabling faster geometric replication of complex computational fluid dynamics (CFD) models for exact experimental validation studies. This methodology is specifically applied to the in vitro flow modeling of patient-specific total cavopulmonary connection (TCPC) morphologies. The effect of RP machining grooves, surface quality, and hydrodynamic performance measurements as compared with the smooth glass models are also quantified.
透明立体光刻快速成型（RP）技术在文献中已被证明是一种用于光流测量的实用模型构建工具，如数字粒子图像测速（DPIV）、激光多普勒测速（LDV）和流动可视化。在此，我们采用了最近可用的透明RP树脂，并省去了传统方法中耗时的铸造和化学固化步骤。本说明详细介绍了我们的方法及相关材料特性，并突出了其优点。采用我们的程序进行立体光刻模型打印现在是一个直接的单步过程，能够更快地对复杂的计算流体动力学（CFD）模型进行几何复制，以进行精确的实验验证研究。该方法专门应用于患者特异性完全腔肺连接（TCPC）形态的体外流动建模。还对RP加工凹槽、表面质量以及与光滑玻璃模型相比的流体动力学性能测量的影响进行了量化。
