Abstract This paper introduces a new subject called bio-manufacturing. Bio-manufacturing combines life science with manufacturing science, and uses manufacturing method to form materials with bio-activity and biodegradability into scaffolds. In this paper, we discuss the hierarchy of bio-manufacturing: the lower grade uses undegradable bio-material to form permanent organ replacement such as auricular cartilage and the higher grade uses biodegradable bio-materials to repair organ damage or organ replacement which degrades after embedded in the human body. They all adopt jetting/ extrusion deposition process (fused deposition modelling or 3D printer), the distinct different point being the temperature of the forming chamber, The samples of bones and auricular cartilage produced by those processes had been practiced on dogs and rabbits, repaired their damage.
