Abstract

The invention discloses a composite support structure construction method and system based on metal 3D printing and an intelligent terminal.The construction method comprises the steps that all triangular patches in a model are traversed, and the triangular patches meeting a preset strategy are stored to form a triangular patch data set; on the basis of the triangular patch data set, combining and storing all the triangular patches which are adjacent in pairs to form a plurality of non-adjacent supporting areas; calculating the attribute value of each support area, and setting the surface precision of each support area; and based on the attribute value and the surface precision of each support area, calculating to obtain the composite support structure. The technical problems that a supporting structure is inconvenient to remove and poor in supporting strength are solved.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a method, system and intelligent terminal for constructing a composite support structure based on metal 3D printing. Background technique [0002] The net near forming technology supported by additive manufacturing technology can completely solve the difficult problem of local processing in conventional processing, endow the parts with comprehensive and excellent properties of isotropy, high density and high strength, and greatly improve the reliability and use of the parts. Longevity is a substantial breakthrough in traditional removal processing technology. Relevant studies have shown that metal parts produced by laser additive manufacturing (3D printing) have dense and fine structures, uniform composition, and mechanical properties reach or exceed the level of forgings. [0003] Among many 3D printing technologies, Selective Laser Melting (SLM) powder additive manufacturi...
