Rapid Microfluidic Device Fabrication Capabilities
Rapid Fabrication of Custom Microfludic Devices $90/part
Get custom microfluidic device fabrication quickly and cost-effectively with Potomac’s FAST TRACK manufacturing process. Our digital fabrication technologies are specifically geared to rapidly turning custom designs into functioning devices at a fraction of the time and cost it takes with traditional manufacturing processes.
Starting with prototyping, you can get a minimum of 10 parts for just $90 per part. And most importantly, if you need to modify your design, manufacturing is just a CAD file change away. Once you are ready to move to higher volume, unit price is typically less than $15 per part.
FAST TRACK includes generating and precisely replicating channel designs in your substrate, laser micromachining vias and holes, as well as bonding cover slips. Clearly, to keep prices this low, Potomac’s microfluidic device fabrication process has specific design parameters that are listed below.
For any microfluidic designs that don’t fit into the FAST TRACK design parameters, we are happy to work closely with you to develop a manufacturing process suited to your application. Please contact us today to discuss how we can help you manufacture custom parts for your next Microfluidic project.

Additional drawing and fabrication guidelines
- Draw closed structure dimensions 20 microns larger than desired fabricated dimension to compensate for fabrication tool size.
- All shapes should be closed and of the polyline (connected lines and/or arcs) or circle types.
- Be sure to account for wall draft. Your drawing will determine sizes at the bottom of the channel or well. Fabricated feature dimensions will be larger than drawn at the top of the channel or well.
- Hydrophilic cover adhesive will be used unless otherwise specified.
Full-feature product and process development
If you microfluidic device fabrication design does not meet the design rules for the FAST TRACK program, please contact us to discuss your application. We can work with you to develop suitable prototyping and production processes for other microfluidic device features, such as:
- Alternative materials: COC, COP, FEP, Polyimide
- Larger or smaller device sizes
- Larger or smaller feature sizes
- Alternative bonding methods: Thermal, solvent assisted
- Multilayer stacks
- Component integration
