            Abstract: Synergies in bioprinting are appearing from individual researchers focusing on divergent aspects of the tech-
            nology. Many are now evolving from simple mono-dimensional operations to model-controlled multi-material, interpe-
            netrating networks using multi-modal deposition techniques. Bioinks are being designed to address numerous critical
            process parameters. Both the cellular constructs and architectural design for the necessary vascular component in digi-
            tally biomanufactured tissue constructs are being addressed. Advances are occurring from the topology of the circuits to
            the source  of  the of the  biological microvessel components. Instruments  monitoring  and control of these activates
            are becoming interconnected. More and higher quality data are being collected and analysis is becoming richer. Infor-
            mation management and model generation is now describing a “process network.” This is promising; more efficient use
            of both locally and imported raw data supporting accelerated strategic as well as tactical decision making. This allows
            real time optimization of the immediate bioprinting  bioprocess based on such  high value criteria as instantaneous
            progress assessment and comparison to previous activities. Finally, operations up- and down-stream of the deposition
            are being included in a supervisory enterprise control.
