3D printing (additive manufacturing)
Based on the 3D model data, the SLM produces the implant which exactly matching with 3D model – fast and in high precision and quality. The parts produced are absolutely true to size, one hundred percent proof and require little post-processing. Compared to the conventional casting technique, producing with the SLM 50 starting at around 100 units per month is economically feasible.
COMPUTER NUMERICAL CONTROL (CNC)
5-axis machining is able to move a tool or a part in five different axes simultaneously. Basic machining operates on three primary axes, X,Y and Z; however, a 5-axis CNC machining tool can rotate two additional axes, A and B, which gives the cutting tool a multidirectional capability.

CNC Milling
This is just the opposite of 3D printing and is also known as subtractive manufacturing technology. IN this case, a block of solid material is being shaped by using cutters or rotating mills. These rotating mills work on digitally fed codes from CAM software and the cutters remove the unnecessary parts of the block all according to the codes. These cutting processes are very accurate. Several geometries can be shaped. In addition, machining has low tooling requirements – reducing fixed costs and lead time. Machining is usually the first choice for rapid, low volume manufacturing, and is used extensively for prototyping, tool production, and short-run production of end use parts. The pain point for machining is its high price and it does not scale well for high volume production. Further shortcomings are high material waste, expensive machinery, and the requirement for skilled programming time. In addition, for hard metals like titanium and tool steel, cutting times and tool wear are very high.
