Zusammenfassung:	The invention relates to a method for preparing a fiber-reinforced article, having attached to at least part of its surface a layer of a material that is not fiber-reinforced, comprising the steps of 1) preparing a shell via an additive manufacturing technique, the shell-being of a material that is not fiber-reinforced; and-having a surface that corresponds in negative relief to a surface of the article formed in step 3); thereafter 10 2) applying-long and/or continuous reinforcement fibers; and-a curable resin to the surface of the shell that is in negative relief, to form a mixture of curable resin and long and/or continuous reinforcement fibers on the 1 surface of the shell, so that the surface of the mixture contacting the shell adopts the shape of the surface of the shell that is in negative relief; thereafter 3) curing the curable resin to form the fiber-reinforced article having attached to at least part of its surface a layer of a material that is not 20 fiber-reinforced.
