We report the fabrication of 3D polymer objects that contain electrical components interconnected by conductive silver/carbon nanotube inks printed conformally onto their surfaces and through vertical vias. Electrical components are placed within internal cavities and recessed surfaces of polymer objects produced by stereolithography. Conformally printed electrodes that interconnect each electrical component exhibit a conductivity of ∼2 × 10 S cm upon annealing at temperatures below 100 °C. Multiple 3D objects were created to demonstrate this hybrid additive manufacturing approach, including those with an embedded circuit operated by an air-suspended switch and a 3D circuit board composed of microcontroller unit, resistor, battery, light-emitting diode and sensor.
我们报告了 3D 聚合物物体的制造，这些物体包含通过在其表面和垂直通孔中打印的导电银/碳纳米管墨水相互连接的电气组件。电气组件放置在立体光刻产生的聚合物物体的内部空腔和凹陷表面内。在低于 100°C 的温度下退火时，相互连接每个电气组件的共形印刷电极表现出约 2×10 S cm 的电导率。制造了多个 3D 物体来演示这种混合增材制造方法，包括那些由气悬浮开关操作的嵌入式电路和由微控制器单元、电阻器、电池、发光二极管和传感器组成的 3D 电路板。
