Lifeink® 240 from Biomatrix is a 35 mg/ml type I collagen bioink that has been specifically developed for extrusion-based FRESH 3D bioprinting. Lifeink® 240 is available with acidic pH and when FRESH printed into LifeSupport® provides a neutralized high-resolution collagen scaffold.

Lifeink® 240 is called an acidic Type I collagen bioink at a concentration having 35 mg/mL available for extrusion-based 3D bioprinting. The product seems to be a highly concentrated acidified collagen solution scheduled to be extrusion printed with the help of a FRESH bioprinting

Lifeink® 240 generates printed structures with a high-print resolution and good mechanical strength. The product has been developed in an acidic saline buffer solution.

As soon as the collagen has been printed into LifeSupport®, the pH and salts concentration of the printed structure turned out to be physiological. Further, cells can be seeded onto the printed structure enabling cellular remodeling and cell adherence of the 3D bioprinted structure.
