Summary
This paper evaluates a resin-printing workflow for making reusable microfluidic templates. The study compares fabrication constraints, template performance, and practical requirements for PDMS chip prototyping.
Key findings
- Resin 3D printing can support rapid microfluidic template prototyping when cleanroom access is limited.
- Channel geometry, feature size, and print behavior need to be measured rather than assumed.
- The method is most useful when speed, cost, and iteration matter as much as perfect fabrication precision.
Methods
The workflow uses resin 3D printing to fabricate molds for PDMS microfluidic devices, then assesses whether the printed templates can support reproducible channel formation at lower cost.
