GelMA A is a blend of GelMA and alginate, offering a larger printability window compared to pure GelMA bioinks due to the softening provided by the alginate. GelMA A can be stabilized through photocrosslinking, or through the addition of the ionic crosslinking solution. GelMA A is a shear-thinning bioink that prints at low pressures and forms filaments once deposited. Available with LAP photoinitiator at 0.25 percent.
