## Summary

Daniel Farbode and Daniel discuss two recent advances in additive manufacturing: Carnegie Mellon University’s method of 3D printing ice to create high-fidelity microfluidic channels for biomedical devices, and MIT’s development of sensing architected materials using embedded air pockets and pressure sensors. The hosts explain how CMU’s ice printing solves support structure issues in resin casting, while MIT’s approach enables soft robotics and wearables to track complex deformations through internal pressure changes. They highlight the potential for these technologies to revolutionize soft robotics, tissue engineering, and motion-capture wearables.
