制造纹理材料和设备的可能性，从设计阶段控制表面特性，而不是机械加工过程或化学攻击的结果，是将先进功能纳入广泛的微米和纳米系统的关键因素。最近开发的高精度增材制造技术，以及与计算机辅助设计工具相关联的分形模型的使用，允许精确定义和控制广泛应用的最终表面特性，尽管基于这些资源的更大系列的生产仍然是一个未解决的挑战。然而，快速原型，与控制的表面形貌，可以被用作原始的母版，用于获得微模具插入使用微注射成型的复制品的最终大规模系列制造。在这项研究中，提出了一个原始的程序，旨在连接快速成型与微注射成型，为两个不同的微纹理微系统的大规模生产，与组织工程任务，使用不同的热塑性塑料作为最终材料。
The possibility of manufacturing textured materials and devices, with surface properties controlled from the design stage, instead of being the result of machining processes or chemical attacks, is a key factor for the incorporation of advanced functionalities to a wide set of micro- and nanosystems. Recently developed high-precision additive manufacturing technologies, together with the use of fractal models linked to computer-aided design tools, allow for a precise definition and control of final surface properties for a wide set of applications, although the production of larger series based on these resources is still an unsolved challenge. However, rapid prototypes, with controlled surface topography, can be used as original masters for obtaining micromold inserts for final large-scale series manufacture of replicas using microinjection molding. In this study, an original procedure is presented, aimed at connecting rapid prototyping with microinjection molding, for the mass production of two different microtextured microsystems, linked to tissue engineering tasks, using different thermoplastics as ultimate materials.
