CandyFab your blood-tubes!
OK, this is a FDM process instead of a CandyFab-like sintering process, but still: this scheme prints a vasculature network out of sugar, grows some cells around it, then washes away the sugar so that the cell culture has a working nutrient perfusion system (if I have the terms right). Neat!
