The orthopedic implants are the essential subparts where the patient gets mobility and increases the life quality after the surgery, before the successful implementation of the implant, every factor related to implant materials and machining process are very important. This report mainly describes the quality of machining technology for implants by the situation based upon the advanced machining. How to select a proper material that has biocompatibility, mechanical strength and it does not react with corrosion are the major part of this report. The abstract lists the main context by many advanced machining technologies, such as CNC machining, electrical discharge machining (EDM), laser machining and abrasive machining. The report tries to talk about the benefits, the limitation and the applications for each kind of process. Process optimization for implants manufacture may need consider the losing of data, the wear of tool and cooling strategy to lower heat damage that may happen during machining. Within the process of orthopaedic implant, the customized tolerance that needed depends on the material used, the sufficient machining technology are needed to get detailed and microscopic characteristics. The use of various speed machining and micro machining is important in order to produce implants need to have those attributes to auto the size and shape of artificial implants. In addition, the report talks about historically the development of additive manufacturing (AM) or 3D printing have a revolutionary impact on many markets. Instead of making a whole part piece one by one, 3D printing can create the end product directly. AM is similar to the fabrication of tissues in biological systems. AMA is defined as a general technology in which materials are joined or solidified under computer control to create three-dimensional objects, with material being added to build an object rather than removed as in traditional subtractive manufacturing techniques. In the end, the report suggests its future development can combine with bio fabrication to improve the production of the implants.
