Abstract

The field of electrostatics offers great potential for applying powder layers for powder-bed-based additive manufacturing processes like Laser based Powder Bed Fusion. In this paper, the possibilities of electrostatics are analyzed in order to derive a recoating system. Hereby, handling of various powder materials marks the main benefit of electrostatic recoaters. Different materials and powder properties can be processed within one building process. When using a photoconductor, powder materials can be applied selectively and thus enable the processing of several materials. The development of such a novel recoater poses many challenges. First, the suitability of the photoconductor material and the analogy of the electrophotographic process for additive manufacturing must be evaluated. Therefore, several experiments were conducted, and a recoater-prototype was designed.
