Development of Planar Technology "Anyone might say without any exaggeration that the issues of structural self-formation is the subject of natural science"[109].
All technological processes in planar technology may be classified as deposition, removal or transformation of material.
I.Prigogine Any real object can be seen as a complex of different materials arranged in a certain manner in Euclidean space.
Manufacture or development of such an object can be perceived as a rearrangement of these materials by either removing or adding new ones.

It is high cost to any parallel materials with good corrosion resistance and mechanical properties, and can not be widely used difficultly.
The process maturity can produce qualified products, but the main problems include: Process complexity and more manufacturing processes; Metal particles collection is low, less than 78%; High energy consumption, 22% of the leftover materials need to return to re-melt scraps, more than 22% more energy consumption; Stamping equipment is huge, strong repair capacity, low labor productivity; High capital investment of equipment; There is contamination of the finished metal particles.

If dimensions, material parameters and characteristic values for heat transfer are known structure-based thermal finite-element models can be derived for a machine tool.
The radiated power emitted by the object depends not only on the surface temperature TObj but also on the material and surface properties.
Τransmittance τ is practically zero for relevant metallic materials.
