RepRapMicron uses fiber optics for micro-scale resin printing
Key Takeaway
The RepRapMicron project has developed a PIKA UV Head that uses fiber optics to achieve 3D printing resolutions down to 9 µm.
Summary
The RepRapMicron (µRepRap) project has introduced the PIKA UV Head, a specialized print head designed for microscopic 3D printing. By combining off-the-shelf optical fiber with UV LED modules, the system can cure resin in-situ to create extremely small structures. Recent demonstrations include a 0.5 mm Benchy boat printed with a resolution of approximately 9 µm.
Technical details of the PIKA UV Head
- Uses a single mode fiber optical cable (modified patch cord) to deliver light.
- Utilizes a 3W UV LED module to cure eSun Standard Resin.
- Achieves a printing resolution of approximately 9 µm.
- Requires standard SLA post-processing, including cleaning the part and the fiber from liquid resin.
Why it matters
This project applies the RepRap philosophy of accessible manufacturing to the microscopic scale using relatively low-cost components.
