All of these systems use high-power beams as heat source to melt and process raw materials, so the price of products, cost of maintenance and usage of these equipments are expensive.
The plasma arc has lots of advantages, such as higher energy density, arc temperature, welding velocity, arc stability, smaller heat affection, wider material applicability, and no splash problem.
Welding torch, wire feeder and three-dimensional worktable work corporately under the control of computer, and the X-Y two-dimensional worktable scans the tracks of the filling according to the geometry shape of current layer, and then fills the molten material.

The noise control was usually associated with sound absorption materials inside to absorb the noise of engine as much as possible and prevent noise from radiating.
Referring to the sound insulation ability of usual single-layer and double-layer materials [6], the 6 mm thick organic glass was chosen as the sound insulation plate, with its length was 135mm, and width was 120mm. when all the working units worked at the rated speed without load, a third octave spectrum of the noise at the driver’s ear after adding the acoustic panel was shown in the Fig.6.

While there are many modern materials with excellent properties, the number of materials which are currently approved for use in surgical practice is far more limited [1].
The value of friction coefficient was similar for both investigated materials.
The passive range, important for metallic implant materials, was significantly shorter.
