The biggest change in our plan was the fabrication of the heart prototype. It was delayed more 3 weeks than what we expected. The major problem was the arrival of our molding materials. Due to a shipping accident, we couldn't get the materials at the expected time. Because of this, we had to spend a lot of time for searching other local distributors.
We did some additional works which was not included in original project plan, such as creating a control circuit, 3D printing of our mold positives and FEA validation. We also spent an extra week for Flow Tuning. The two figures below are the original time table which we expected at the beginning of this quarter and the time table reflecting the our actual progress throughout the spring quarter.
