Additive manufacturing (AM) is a novel materials processing approach to create parts or prototypes layer-by-layer directly from a computer aided design (CAD) file.The combination of additive manufacturing and biomaterials is very promising,especially towards patient specific clinical applications.Automatic hardfacing and arcing on mill rolls.The FCAW process was applied in many mills under conditions where the variety of sugarcane,the cutting process,the ratoon,the size of mill,and the number of tandems were different.Results showed that the time spent on hardfacing was almost 70% less than the time spent on the traditional process known as Shielded Metal Arc Welding (SMAW).
