FORCE REPAIR Showcased at CMBBE 2025

The FORCE REPAIR project was recently presented at the 20th Anniversary of the Computer Methods in Biomechanics and Biomedical Engineering Symposium (CMBBE). The event took place in Barcelona, Spain, from 3 - 5 September and brought together experts in biomechanics and biomedical engineering.

Our partner, Vicomtech, and their researcher, María Basañez Elorrieta, presented the latest advances in optimizing extrusion-based bioprinting parameters, with a focus on computational modeling for tissue engineering. The participation not only increased the project’s visibility in the bioprinting community but also fostered new scientific exchanges and potential collaborations.

María Basañez Elorrieta, presented her poster titled Optimization of extrusion-based bioprinting parameters using CFD simulations and DoE showcasing how Computational Fluid Dynamics (CFD), rheology, and Design of Experiments (DoE) can be combined to better understand bioprinting. Key findings include:

• Bioink viscosity and nozzle geometry are dominant factors influencing wall shear stress during bioprinting, with conical nozzles strongly reducing shear stress compared to cylindrical ones.
• Outlet diameter plays a critical role, while piston velocity has only a minor effect within the tested range.
• A predictive model has been developed to estimate shear stress, offering a practical tool to guide bioprinting process planning.

The participation at CMBBE 2025 demonstrated FORCE REPAIR’s commitment to advancing computational modeling approaches for tissue engineering. The final conference poster is now available on the FORCE REPAIR Outcomes page.
