Description
The Department of Veterans Affairs, Iowa City VA Healthcare System Research Department, is seeking information on 3D bioprinters for a research project. The project aims to use 3D bio-printed human corneal endothelial grafts as a renewable source for endothelial keratoplasty transplantations. The bioprinter should have specific features such as high-precision material deposition, UV/temperature/chemical/enzymatic/pH-sensitive crosslinking, and camera-guided printing.
Some key features of the required equipment include:
• High-precision material deposition on curved surfaces
• Combination of extrusion printing for high-viscosity biomaterials with droplet-based nanoliter deposition
• 5-way multi-crosslinking capabilities
• Camera-guided printing with a high-resolution camera
• Contact lens specific printing capability
• Software allowing real-time printing location determination via camera feed
