Additive manufacturing (also known as 3D printing) has begun to spread for prototyping at-point-of-use biosensing platforms since allows the custom and decentralized fabrication for on-demand low-cost devices and actuators. Although this research is still in an early stage, 3D printing of bioanalytical platforms can offer enormous potential in several fields, including electrochemical and optical devices; however, some pivotal aspects must be solved in order to achieve active and stable 3D-printed biosensing systems. Accordingly, an overview of printing techniques and recent bio-functionalization of 3D-printed devices for biosensing applications is provided, pointing out the advantages, disadvantages and future opportunities of this technology for the determination of biologically active molecules readout by electrochemical and optical techniques.

增材制造（也称为3D打印）已开始普及，以在使用时的生物传感平台上进行原型制作，因为它允许按需定制和分散制造按需的低成本设备和执行器。尽管这项研究仍处于早期阶段，但生物分析平台的3D打印可以在多个领域提供巨大的潜力，包括电化学和光学设备。但是，必须解决一些关键问题才能实现主动和稳定的3D打印生物传感系统。因此，提供了用于生物传感应用的印刷技术和3D打印设备的近期生物功能化的概述，指出了该技术用于确定通过电化学和光学技术读出的生物活性分子的优点，缺点和未来的机会。
