Due to the alginate’s softening effect, GelMA A, a mixture of GelMA and alginate, offers a wider printability window than pure GelMA bioinks. Both photocrosslinking and the addition of an ionic crosslinking solution can stabilize GelMA A.

A shear-thinning bioink called GelMA A can be printed at low pressures and, after being deposited, forms filaments. Available at 0.25% with LAP photoinitiator.
