Enhancing Bioprinting Precision through Real-Time Monitoring of Stand-Off Distance: a preliminary study

The rapidly evolving field of 3D bioprinting holds immense promise for tissue engineering and regenerative medicine, yet achieving high-quality structures remains challenging, making the development of monitoring techniques crucial. This work presents a cutting-edge real-time monitoring technique in bioprinting. Through a digital microscope it is possible to accurately assess the distance between the extruder and the substrate in real-time, providing crucial data for optimizing parameters. Experiments were performed using Gelatine Alginate at different concentrations. The sensor’s integration enables continuous monitoring, offering instant feedback on printing quality, enhancing overall bioprinted structure quality and moving towards automated, closed-loop control systems.
