Challenges and Materials in Artificial Organ Manufacturing

Additive manufacturing (AM), is also known as rapid prototyping, is considered as a revolution in field of manufacturing and fabrications and boosted the development in biomedical fabrication. The 3D printing technique is mostly utilized in the field of medical for the manufacturing of medical equipment and surgical equipment, especially 3D biomedical printing which means 3D printing of substance which are biologically compatible to human body, blood and cells in the field of tissue fabrications. The main aim of tissue fabrications and engineering is to produce the artificial organ which is functional and viable. To fulfill this objective, investigation of various manufacturing techniques and materials is required. The process is difficult as it includes multiple aspects of human physiology, like types of multiple cell culturing, vasculature, nerve innervation, and interactions with nearby cells. This paper objective is to find the suitable material, is difficult task and, need in-depth focus on why it is difficult & what are the factors influencing the negative role of effective utilization of 3D printing tissue engineering. Also, this paper focuses on comparative study of materials in economic perspective human organ manufacturing. At the end, the conclusion elaborates about the applications and challenges of additive manufacturing in medical field and the alternative materials for organ tissue manufacturing.
