Abstract

The invention discloses a printing method and device. The method comprises acquiring a vector graph file; identifying a first vector graph source contained in the vector graph file; Judging whether there is overlap between the first vector map sources, and fusing the overlapped first vector map sources to obtain at least one second vector map source; generating a print trajectory from at least oneof the second vector map sources; printing low melt point metal with a melting point not higher than 300 DEG C on the surface of the printed substrate according to the printing trajectory to form a printed circuit. By re-integrating the vector drawing source before generating the printing track, the invention avoids the problems such as scratching and overflowing of the low-melting-point metal ofthe solid state at normal temperature and the liquid state at normal temperature during / after the printing process, and guarantees the printing quality of the printed circuit.

Description

technical field [0001] The invention belongs to the technical field of additive manufacturing of electronic circuits, and in particular relates to a printing method and device. Background technique [0002] Liquid metal (also known as low-melting point metal) is a new material for additive manufacturing technology. Because it is far lower than the melting point of traditional metal materials such as copper, aluminum, and silver, the complexity, energy consumption, safety and environmental protection of the production equipment The supporting facilities are greatly simplified, which provides a basis for rapid on-site manufacturing of electronic circuits. [0003] As the carrier equipment of liquid metal additive manufacturing technology, the liquid metal printer can use the corresponding printing equipment to quickly manufacture the designed vector file on site. At present, the best printing effect among liquid metal printers is the liquid metal direct-write printer, which d...
