Description
GelMA bioink is a gelatin-methacrylate-based formulation designed for high cell compatibility and tunable mechanical properties. The bioink requires gentle heating prior to extrusion, ensuring smooth printing with temperature‑controlled printheads. GelMA bioink crosslinks through photocuring, allowinging for tailored construct stiffness and well‑defined 3D tissue‑modeling structures.
Recommended for use with BIO X, a temperature-controlled printhead and a cooled printbed, or INKREDIBLE+ with a heated printhead. Not recommended for use with INKREDIBLE.
Advanced formulations based off of CELLINK GelMA
