The biggest challenge in tissue printing is the achievement of sufficient control over small scale structure to produce a vasculature that can supply the tissue as it develops. Without that capacity, tissue growth is limited to thin sheets and tiny organoids. Advances have been made in recent years, such as the work of Volumetric, but there is still a way to go before large tissue sections are regularly generated for use in medicine.
