The authors introduce a highly flexible powder layer forming process using the electrophotographic principle. The focus is on full-area powder attraction by electrostatic mass transport of a typical gas atomized PBF-LB/M steel alloy (20MnCr5). A simulation model was created to predict the formation of the electric field. This model was used to determine parameter preselection for experimental validation. After successful full-area powder attraction, a selective powder attraction approach was investigated.en537journal article
