a method for producing three - dimensional sintered work pieces , in particular a stereo lithography method for application in a laser sinter machine , in which a sinter material , in particular liquid , pasty , powder or granular sinter material is applied in layers from a reservoir onto a backing and heated by partial irradiation of prescribed individual sections such that the components of the sinter material are combined to give the work piece by partial or complete fusion in regions dependent on the irradiation . the serially irradiated individual sections have a separation from each other , greater than or at least equal to average diameter of the individual sections .
