With the continuous development of modern manufacturing industry, the continuous generation of advanced manufacturing modes and the innovation of the original technology, the old cutting process can not meet the requirements, particularly, the processing of precise and complex three-dimensional structures is not careful, and the additive manufacturing technology is gradually developed and occupies more and more important positions in the fields of scientific production and the like. The precise sample control device is indispensable to three-dimensional additive manufacturing, and the processing device itself can not move in a flexible way because of reasons such as structure, principle, wants to realize the precision finishing of different space coordinates departments, just needs positioner to carry out accurate motion control to the material to guarantee the accuracy of processing position and the shape stability of material itself, more nimble accurate controlling means can promote the range that additive manufacturing can be processed more, promotes the quality of product simultaneously.

Meanwhile, the additive manufacturing technology is a main processing mode of a high-performance micro sensor and printing electronics, and the maskless characteristic of the additive printing technology can be used for defining a more complex conductive line structure. Additive printing techniques are mature to date in the processing of planar microstructures. However, the two-dimensional planar structure has many limitations in the field of sensors, such as too large area, difficulty in miniaturization, and the like. The micro-diameter columnar structure has the advantages of large specific surface area, small volume and the like. Particularly in the field of implantable sensors, biosensors with micro-diameter columnar structures often occupy smaller volume to realize required functions, so that health monitoring and disease treatment of human bodies are realized under the condition of reducing the risk of immunological rejection of the human bodies. However, since the sample structure is a cylindrical three-dimensional structure, the structure is more difficult to fix and move than a planar structure, and multi-dimensional surface printing of the whole area is not easy to realize.
