The group of Prof. Juergen Brugger (LMIS1 - Laboratoire de microsystèmes 1) demonstrates an optimized 3D inkjet printing process for structuring alginate into a tissue-like microvasculature capable of supporting physiological flow rates. Optimizing the reaction at the single-droplet level enables wet hydrogel droplets to be stacked, thus overcoming their natural tendancy to spread and coalesce. Live cells can be patterned using this process and it can be extended to a range of other hydrogels.
