Thus, alternative process is prominent and DLP projector has been seen capable of polymerised photopolymer materials.
Thus, there is a need to explore the possibility of using DLP projector as it was proven before that DLP projector had succesfully polymerised a photopolymer materials [6].
Curing is a process to crosslink the polymer materials.
ZArcing is the result of excessive charge build-up in metallic materials in the presence of standing wave patterns.

Abstract.
Cycling is an important project accounting is accounting for warranty costs, maintenance and minor repairs categories of diversity of the frequent maintenance expenses of management as weak, with real-time settlement system, strengthening the process of consumption Bus maintenance control, improve material consumption transparency, the main question of the contract specifications settlement relationship, with clear, repair both sides Zequan Li, reflecting the cost and value of consistency, to eliminate the occurrence of waste, materials, fixed by changing the existing settlement pattern, each maintenance operation project must be confirmed both mechanic and pilot, and description section of the distribution system reform, the pilot of the pilot material savings incentives, and the material has been effectively monitored, making financial accounting segment, management processes and further transformation.

With this emerging technology, it is possible for the first
time to rapidly deposit thin or very thick layers (mm to cm+) of a wide range of metals, and even some
composite materials, without melting or vaporization, at or near room temperature, in an ambient air
environment.
Introduction Cold spray [1-7] is a new coating method for the deposition of metal, alloy, polymer, or composite powder material onto various substrates.
The cold spray process was developed in the mid-1980s at the Institute for Theoretical and Applied mechanics of the Russian Academy of Science in Novosibirsk.
As shown in the figure, the distinguishing feature of the cold spray is the ability to produce coatings with the jet temperature range between 0 and 700͠, which is always lower than the melting point for the candidate powder and substrate materials.

Effective method of the solution of this problem is direct processing of mineral raw materials with receiving composite materials according to the main conclusions of a mineralogical materialogy [1, 2] consisting in need of reduction of the periods between a cycle of receiving raw materials, its processing and a cycle of receiving materials, and also reductions of the periods in each cycle, at the expense of use of high technologies, i.e. receiving materials in the region of production of raw materials.
