Additive printing of metal parts of complex shape

Additive printing of metal parts of complex shape.

 

 

Giving details of cellular (honeycomb) structures using additive layer technology print metals, in particular by selective laser melting reduces the weight of the resulting simple and Konopasevich parts by 50%, while maintaining its strength and other technical and functional characteristics.

 


Description:

Every detail represents the volume of a massive monolith, made of metal, a substantial amount of material which does not bear any functional load, that is, contains, in fact, superfluous metal. It is found that the load it carry and transmit, for example, only about ten points of the fasteners.

Giving details of cellular (honeycomb) structures using additive layer technology print metals, in particular through selective laser melting (selective laser melting). Technology layer-by-layer printing of metals, in particular, selective laser melting as a method of manufacturing complex metal parts is low cost and the ability to create objects of any shape.

It (the technology) allows to reduce the weight of the resulting simple and Konopasevich parts by 50%, i.e. almost half, while maintaining its strength and other technical and functional characteristics. At the same time parts with a cellular structure carry loads similar to conventional cast parts.

Relief items, for example, in the manufacture of engines of vehicles, leads to the reduction of consumption of fuel, the load on the roadway, reducing the amount of harmful emissions into the atmosphere, reducing the amount of metal to manufacture the part, etc.

The level of mechanical properties of parts with cellular (cell) structure depends on the configuration of cells, their elements and the volume of voids. The calculation type and configuration of cellular structures which allow the maximum level of functional and technical properties, by using specialized Russian software for topological optimization.
