Conventional photopolymerization-based 3D printing still requires developing a concise and cost-effective method to improve the printing resolution at the nanoscale. Here, we propose the use of a gaming console optical drive pickup unit for 3D photopolymerization. This mass-produced optical pickup unit features a finely adjustable diode laser, allowing us to adjust the printing resolution from tens of micrometres down to hundreds of nanometres without requiring oxygen radical scavenging or costly femtosecond lasers. We evaluate the 3D printing performance using a commercial photopolymer under different laser exposure parameters. The proposed printing system achieves a resolution of 385 nm along the lateral direction and XYZ nano-resolution linear stages enable a printing volume of up to 50 × 50 × 25 mm3. Finally, we demonstrate the fabrication of 3D stereoscopic microstructures. The substantially simplified optics proposed here paves the way for affordable high-resolution micro/nanoscale 3D fabrication.

使用游戏机上的光学头组件进行微米和纳米级3D打印
常规的基于光聚合的3D打印仍然需要开发一种简洁且经济高效的方法来提高纳米级的打印分辨率。在这里,我们建议使用游戏机光驱拾取器单元进行3D光聚合。这种批量生产的光学拾取器具有可调节的二极管激光器,使我们可以将打印分辨率从几十微米降低到数百纳米,而无需清除氧自由基或昂贵的飞秒激光器。我们使用市售光敏聚合物在不同的激光曝光参数下评估3D打印性能。拟议的打印系统在横向方向上实现了385 nm的分辨率,XYZ纳米分辨率的线性平台可实现高达50×50×25 mm 3的打印量。最后,我们演示了3D立体微观结构的制造。本文提出的大幅简化的光学器件为可负担的高分辨率微/纳米3D制造铺平了道路。
