Official Abstract

#

“Microfluidic has emerged as a strong tool in several domains, including biology, chemistry, and medicine. However, manufacturing microfluidic devices using traditional techniques such as photolithography and soft lithography may be costly and time-consuming. In this research, we described a low-cost microfluidic device production approach based on a 3D printer. The 3D printer employs digital light precision technology to produce microfluidic devices with extreme precision and accuracy. Using this technology, microfluidic devices are created, showcasing its potential for usage in lab-on-a-chip and sensor applications. Our findings show that the 3D printer can produce high-quality microfluidic devices for a substantially cheaper cost than previous approaches.”

Technical Highlights & Key Innovations

#

• Digital Light Precision (DLP) Fabrication: Utilizes DLP resin 3D printing technology to achieve extreme accuracy and sub-millimeter microchannel geometry without inter-layer leakage.
• Replacement of Cleanroom Lithography: Bypasses conventional, expensive, and time-consuming cleanroom processes (such as silicon photolithography and soft lithography / PDMS molding).
• Rapid Prototyping: Enables high-speed iterative design of microfluidic architectures directly from CAD models to finished functional chips in a fraction of the time.
• Lab-on-a-Chip & Sensor Integration: Successfully demonstrated for chemical reactions, fluidic manipulation, and sensor integration (including real-time pH measurement).
