PCT No. PCT/EP93/00344 Sec. 371 Date Aug. 26, 1994 Sec. 102(e) Date Aug. 26, 1994 PCT Filed Feb. 12, 1993 PCT Pub. No. WO93/16865 PCT Pub. Date Sep. 2, 1993The invention relates to a process for the production of porous shaped articles having a predetermined pore structure by shaping a composition which can undergo plastic deformation and then be solidified, which is characterized in that the shaped article is built up in the form of layers by repeated sequence of the steps A. Production of a layer of the composition structured in an image-wise manner corresponding to the pore system, and B. Solidification of the layer the image structures of the individual layers being transferred from corresponding models. This process can preferably be used for the production of shaped articles having a three-dimensionally interconnecting pore system, and in particular for the production of shaped implants having the pore system of natural bone.
