Minimal invasives in-situ Bioprinting mittels schlauchbasiertem Materialtransport

Minimally invasive in situ bioprinting can potentially enhance the advantages of bioprinting, allowing the surrounding healthy tissue to be maximally preserved. However, the requirements for such a device are manifold and challenging to fulfill. We present an experimental bioprinting platform consisting of an extrusion system based on a tube mounted between an extrusion syringe and a dispensing nozzle. We investigated the influence of material transfer through a tube on the printing outcome. The results showed that it is feasible to form a continuous filament and print 3-dimensional structures using the developed platform.ISSN:0178-2312ISSN:2196-677
