A method for producing a component (1) from hardenable material, wherein, in a first method step, at least one layer (2, 3) of the material is printed in a 3D printing process, in a second method step, multiple similar reinforcing elements (4) are introduced into the layer(s) (2, 3) and the two method steps are cyclically repeated until the component (1) is completed, characterized in that, with the exception of the two bottommost and the topmost layers, each reinforcing element (4) extends over at least three layers (2, 3), and the reinforcing elements (4) are arranged in strands (5) which extend through all the layers (2, 3) and have, in each layer (2, 3), at least three reinforcing elements (4), the lateral distance (A) of these reinforcing elements from each other within a strand (5) being a maximum of five times the largest lateral extent (D) of a reinforcing element (4).
Method for producing a component (1) from hardenable material, in a first step at least one layer (2, 3) of the material being printed in a 3D printing method, in a second step a plurality of similar reinforcement elements (4) being inserted into the layer(s) (2, 3), and the two method steps being cyclically repeated until the component (1) is complete, characterized in that, with the exception of the two lowermost and uppermost layers, each reinforcement element (4) extends over at least three layers (2, 3), and the reinforcement elements (4) are arranged in strands (5) which extend through all the layers (2, 3) and comprise at least three reinforcement elements (4) in each layer (2, 3), the lateral spacing (A) of which from one another within one strand (5) is at most five times the greatest lateral extension (D) of a reinforcement element (4).
Method according to any of the preceding claims, characterized in that the reinforcement elements (4) consist of a rigid material, in particular metal, in particular steel, and are inserted into the not yet hardened layers (2, 3) of the hardenable material.
Method according to any of the preceding claims, characterized in that the strands (5) extend perpendicularly to the layers (2, 3).
Method according to any of the preceding claims, characterized in that the reinforcement elements (4) are bar-shaped.
Component (1) made of hardenable material, which comprises a large number of layers (2, 3) produced in a 3D printing method as well as reinforcement elements (4) connecting said layers, characterized in that, with the exception of the two lowermost and uppermost layers, each reinforcement element (4) extends over at least three layers (2, 3), and the reinforcement elements (4) are arranged in strands (5) which extend through all the layers (2, 3) and comprise at least three reinforcement elements (4) in each layer (2, 3), the lateral spacing (A) of which from one another within one strand (5) is at most five times the greatest lateral extension (D) of a reinforcement element (4).
