Now that we have 3D-printers in the 20.309 lab, we can print our own in-house master molds to customize the PDMS microfluidic chips.
Mold Dimensions and Specifications
Cleaning Protocol
Leftover, uncured resin on the molds will prevent the PDMS chips from crosslinking and hardening — you'll end up with goopy chips. To ensure all uncured resin is washed off, consider the following advice and cleaning steps:
1. Do several short washes in the Form Wash Instead of one long 10-minute wash, consider interleaving shorter 5-minute washes with compressed air drying. The uncured resin likes to stick between the herringbone ridges
2. Let the parts soak in DI water overnight
