Powder bed 3D printing processes for producing elastic molded silicone articles and silicone resin-containing powders suitable for the processes are provided. The processes comprise: a) layer-by-layer spreading of a powder in a powder bed 3D apparatus, wherein the powder contains a silicone resin of formula (I); b) applying a crosslinker solution to the layer of a) according to a printing pattern for the elastic molded article, wherein the crosslinker solution comprises a hydrosilylation catalyst and a silicone oil of the general formula (II); c) repeating a) and b) according to the printing pattern for the elastic molded body; and d) removing of the non-crosslinked powder.
