I volunteered in a tissue engineering lab and we were working on trying to make a bio-ink with a decellularized pig heart.
We had researched previous inks and composition models and did what we had to do. At the end of it all, we were ready to put it through the printer and then we had realized that the printer heats up during the printing process for prolonged exposure and practically ruined our composition. We had spent the entire summer on the project and were so close to finishing but yet it was that simple factor we didn’t consider that put us back a full 4 months
