Definitions
- the present invention relates to a method for producing a copper-containing component by means of selective laser sintering. Furthermore, the present invention relates to a copper-containing component which has been produced by means of the method according to the invention. It is known from the prior art that selective laser sintering is used for producing a copper-containing component. Due to the high reflectivity of copper over a wide wavelength range of laser radiation, high power lasers must be used to cause reflow of a copper-containing metal powder.
