Abstract: A method for prepares low melting point metal particles, a conductive paste and a method for preparing the conductive paste, and relates to the technical field of functional materials. The method for preparing low melting point metal particles includes providing an organic resin carrier having fluidity, adding a low melting point metal material and the organic resin carrier into a sealed container for a vacuuming operation or filling a protective gas, making a temperature in the sealed container higher than the melting point of the low melting point metal and performing dispersion by stirring, and lowering the temperature, after performing the dispersion, to be below the melting point of the low melting point metal with continuous stirring during a cooling process to obtain low melting point metal particles dispersed in the organic resin carrier. Low melting point metal particles can be effectively prepared.

Abstract: Selective laser solidification apparatus is described that includes a powder bed onto which a powder layer can be deposited and a gas flow unit for passing a flow of gas over the powder bed along a predefined gas flow direction. A laser scanning unit is provided for scanning a laser beam over the powder layer to selectively solidify at least part of the powder layer to form a required pattern. The required pattern is formed from a plurality of stripes or stripe segments that are formed by advancing the laser beam along the stripe or stripe segment in a stripe formation direction. The stripe formation direction is arranged so that it always at least partially opposes the predefined gas flow direction. A corresponding method is also described.
