This week’s work has focused on printing the gel in multiple layers. This is tricky, because the gel hardens slowly. If the next layer is deposited immediately after the previous, the ink merely flows into and inflates the previous layer. So instead, the printer must wait for some time before printing another layer. In that time, though, the print nozzle will cool and the gel inside will clog. Therefore, the nozzle must be reheated manually with a water vial before it can restart. Since the printer software itself doesn’t have settings for this, my solution will be to manually code the behaviors into the instruction file. While the process will now take much longer than an uninterrupted print job with this printer, I find it necessary to ensure a good quality product.
We are finalizing our elevator pitches and running through interview questions. We are practicing them with each other to prepare us for our final presentation at this week’s workshop. I’m shaping my words to be natural and conversational, so that it is engaging and inviting for the interviewer. With this coming workshop being the last, I hope to have a good product to show for what we’ve been working on.
This weekend the cohort made a trip to Busan. It is the second largest city in South Korea, and truly an impressive sight. I got a day off work and left Daejeon on Thursday night, while some of the researchers arrived a day before me and the rest a day later. We visited Haeundae Beach, the Peace Park, the Haedong Yonggungsa Temple, the Shinsegae Centum City mall (once the largest in the world; truly massive above ground and under), among many other things. We stayed in a hostel, which let us meet more strangers and foreigners.

I feel I only did a fraction of what the city has to offer. Who knows how long I could stay in Busan before running out of things to do?
