The utilization of meat by-products (e.g., heart, liver, kidney, intestines, and tongue) is necessary due to their adverse effects on environment. Livestock by-products represent about 52% of the cattle live weight. Since greater amounts of animals live weight is rendered unfavorable for regular consumption, it becomes important to develop technologies for the effective utilization of meat by-products. Furthermore, the large scale disposal of meat by-products in landfills raises environmental concerns. In this regard, their reuse in 3D printing technology could be an alternative.
