The primary objective was to develop a functional microfluidic cartridge that effectively demonstrated Gener8’s ability to design and manufacture complex fluidic systems. The cartridge needed to integrate a variety of microfluidic features, including:

• Microfluidic channels

• Rotary, slider, and check valves

• Laser and ultrasonic weldments

• Hydrostatic venting

• On-board liquid buffers

• Integrated pumps

We followed a structured approach to achieve the project’s objectives:

• Designed a user-friendly fluidic workflow incorporating essential microfluidic features.

• Engaged with many engineers at Gener8 to determine the most impactful design elements to include.

• Created 3D models of the cartridge using SOLIDWORKS.

• Utilized rapid prototyping methods, including 3D printing & laser cutting, to validate design concepts.

• Ensured the design was optimized for injection molding to facilitate efficient manufacturing.

The final microfluidic demonstration cartridge featured a robust design that enabled fluid metering and directional control via integrated pumps and valves. Additional project outcomes included:

• Development of laser welding, ultrasonic welding, and heat staking processes and fixtures for cartridge assembly.

• Creation of detailed work instructions for manufacturing and assembly.

• Deployment of the cartridge as a demonstrative tool to highlight Gener8’s expertise in microfluidic product development.

By successfully designing and fabricating the microfluidic demonstration cartridge, Project Maverick provided Gener8 with a compelling proof of concept for prospective clients. The cartridge not only demonstrated the company’s technical proficiency but also served as a key asset in customer engagements, illustrating the potential applications of Gener8’s microfluidic technology in real-world scenarios.
