GelMA A is a result of a unique blend of GelMA and alginate, which provides the most advantageous gelatin-based bioink in the world. This blend exhibits unparalleled printability at room temperature with a minimal risk for nozzle clogging, even in bioprinting systems with no thermal control. Crosslinking is possible through either the UV activation of the photoinitiator or through the addition of our ionic crosslinking solution, which allows tuning the mechanical properties of printed constructs for the best match with desired engineered tissues.


GelMA A is compatible with most mammalian cells. It can be utilized as a base material for a wide range of tissues. This bioink has been optimized for use with the BIO X system and temperature controlled printhead with thermal nozzle cover and the use of a cooled printbed. While the bioink can be used with the INKREDIBLE+ system due to its ability to heat the bioink, secondary steps are necessary to cool the printed structure to pre-gel it prior to crosslinking. Clogging may still occur due to lack of temperature control at the nozzle. Therefore, it is not recommended to use the bioink with the INKREDIBLE system since the bioink will not perform as expected and resulting filament characteristics may be inconsistent.
