Micro and nanoscale 3D printing using optical pickup unit from a gaming console

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