Abstract


Synergies in bioprinting are appearing from individual researchers focusing on divergent aspects of the technology. Many are now evolving from simple mono-dimensional operations to model-controlled multi-material, interpenetrating 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 digitally biomanufactured tissue constructs is 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. Information 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.
