Abstract: A three-dimensional product is produced by providing a support medium in a container, introducing a production material into the support medium by means of the at least one insertion nozzle, and curing the production material. In the process, the support medium contains particles made of solid matter.

Abstract: A method for producing a 3-dimensional object having a base body which is produced in an additive manufacturing process, in which a base body material in a flowable state is introduced into a support material by at least one insertion needle (10) and cures therein at least partially, wherein the method has the following steps: Providing data of the object to be produced, which contain information about its 3-dimensional shape, determining printing parameters from the data provided, wherein a printing path is determined along which the insertion needle is moved through the support material, and a volumetric flow rate of the base body material inserted into the support material and/or the velocity of the insertion needle at each point along the printing path are determined, producing the base body by means of the additive manufacturing process using the determined printing parameters.

Abstract: A method for producing at least one wall of a three-dimensional object includes an additive manufacturing process in which at least one manufacturing material is fed in a free-flowing state from at least one feed-in opening of at least one feed-in needle into a supporting material and then cures. The wall extends along a course which comprises a first lateral surface and a second lateral surface opposite the first. The feed-in needle is moved through the supporting material along a printing path, and the printing path corresponds to a path of progression along the course of the wall on which a texturing path is superimposed.

Abstract: The invention relates to an orthopaedic socket for bearing on and for receiving a limb stump or a limb, having at least one socket wall (2), a proximal access opening (3), a distal end (4) and at least one fastening device (5) which is arranged for fastening at least one distal orthopaedic component (6) to the socket (1), wherein at least one stiffening element (40) is arranged or formed on or in the socket wall (2), said stiffening element being assigned an adjustment device (30) and by means of which a stiffness of the socket wall (2) is reversibly variable at least in certain regions.

Abstract: A method for producing a three-dimensional object by an additive manufacturing process includes introducing at least one manufacturing material fed in a flowable state from at least one feed-in opening of at least one feed-in needle into a supporting material. After being fed in, the at least one manufacturing material is cured, but it remains flexible or elastic after curing. The contour and/or position of at least one part of the three-dimensional object within the support material is detected by at least one sensor.
