Abstract
A process is described for producing a three dimensional structure, the process including the following steps a) applying of at least a first material Monto a substrate to build a first layer Lon the substrate; b) layering of at least one further layer Lof the first material Mor of a further material Monto the first layer L, wherein the at least one further layer Ly covers the first layer Land/or previous layer Lat least partially to build a precursor of the three dimensional structure; c) curing the precursor to achieve the three dimensional structure; wherein at least one of the materials Mor Mprovides a Mooney viscosity of >10 ME at 60° C. and of <200 ME at 100° C. before curing and wherein at least one of the first material Mi or of the further material Mis a powder. Also, a three dimensional structure is described which is available according to the process according to the invention.
