Abstract

See full text

A process is described for producing a three dimensional structure, the process including the following steps a) applying of at least a first material M1 onto a substrate to build a first layer L1 on the substrate; b) layering of at least one further layer Ly of the first material M1 or of a further material Mx onto the first layer L1, wherein the at least one further layer Ly covers the first layer L1 and/or previous layer Ly−1 at 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 M1 or Mx provides 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 Mx is a powder. Also, a three dimensional structure is described which is available according to the process according to the invention.
