Abstract
Over the last two decades 3D bioprinting has gained momentum to fabricate tissue mimicking constructs serving as tissue models, animal-free drug screening platforms and tissue replacements for regenerative medicine. Recently, the focus has shifted towards the development of light-based bioprinting methods due to its high accuracy and absence of nozzle-induced shear stress on printed cells. However, light-based bioprinting equipment can be costly and photo-sensitive materials difficult to optimize. In this work, we present the conversion of a masked stereolithography printer into a heated, humidified, and easily sterilizable bioprinter, with minimal financial investment (<350 € including purchase of the printer). We provide instructions on how to optimize bioinks and printing conditions and explore novel bioresin additives utilizing cell-friendly photon absorption and radical scavenging…
