The third step for me to understand what it would take to 3D bio print an actual brain was to find exhibitions and seminars about 3D bio printing. Unfortunately, I was not able to find any exhibitions or seminars on 3D bio printing but I was able to find videos on the subject and I found that those were pretty close to exhibitions and seminars since they were explorative and explanatory. The videos are: https://www.youtube.com/watch?v=x1Q2oLxEOF8 (A relatively recent video on the 3D bio printing of leather and meat. It discusses how the process works but also talks about the effects 3D bio printing leather and meat has on the population), https://www.youtube.com/watch?v=d51HyGCVLJk (This video shows the process in which BBC News Researchers try to 3D bio print body parts and it focuses on the difficulties that come with trying to 3D print a body part) and https://www.youtube.com/watch?v=9D749wZSlb0 (This video talks generally about 3D bio printing and how cells would need to be arranged during bio printing to be successful).
