Organs-on-a-chip, or OoCs, are microfluidic tissue culture devices with micro-scaled architectures that repeatedly achieve biomimicry of biological phenomena. They well positioned to become the primary pre-clinical testing modality as they possess high translational value. Current methods fabrication have facilitated development many custom OoCs generated promising results. However, reliance on microfabrication and soft lithographic techniques has limited their prototyping turnover rate scalability. Additive manufacturing, known commonly 3D printing, shows promise expedite this process, while also making easier more reproducible. We briefly introduce common printing modalities before identifying two sub-types vat photopolymerization - stereolithography (SLA) digital light processing (DLP) most advantageous for future OoC development. then outline motivations shifting requirements printed be competitive current state art, several considerations achieving successful touching design techniques, including a survey commercial printers resins. In all, we aim form guide end-user facilitate in-house generation along translation these important devices.
