A 3D printing apparatus comprising a build platform (1), an extruder head (2), whose outlet is directed towards the lateral surface of the build platform (1), and at least one pushing element (3), which is positioned in the peripheral region of the build platform (1) so that it is adjacent to its side surface, a drive system (5) configured to cause rotation of the build platform (1) relative to the at least one pushing element (3) and the extruder head (2), wherein the at least one pushing element (3) has a pushing surface (7) positioned at a height greater than the outlet of the extrusion head (2) relative to the build platform (1), such that during the printing process, the rotational movement of the build platform (1) causes the pushing surface (7) to make contact with the extruded and hardened material at a position that forces the material to be pushed away from the extrusion head (2).

The present invention relates to a rotor (1) of an electric synchronous motor with permanent magnets, comprising: a substantially cylindrical rotor body (2) in which at least two receiving channels (3) are formed, in which at least two permanent magnets (4) are disposed, wherein the rotor body (2) has, in the region of the outer surface, a plurality of circumferentially disposed outer slots (5) in which outer bars (6) are inserted, and, in the region closer to the rotational axis of the substantially cylindrical rotor body (2), a plurality of circumferentially disposed inner slots (7) in which inner bars (8) are inserted, end rings (9) which electrically connect the outer bars (6) and/or the inner bars (8), forming an outer cage and an inner cage respectively, wherein the ratio of the electrical conductivity σ<ext> of the material of the outer bars (6) to the electrical conductivity σ<int> of the material of the inner bars (8) falls within the range of 0.17 to 0.35. The present invention also relates to an electric synchronous motor with permanent magnets comprising such a rotor.

The present invention relates to a method for producing a monoprotein nutritional product, especially for veterinary patients, comprising steps in which: a) selection (1) of meat raw material is carried out by selecting meat raw material from one type of tissue, derived from one animal, b) preliminary preparation (2) of the meat raw material is carried out, c) the meat raw material is preliminarily comminuted (3), d) the preliminarily comminuted meat raw material is freeze-dried (4) using a freeze-dryer, e) heat treatment (7) of the dried preliminarily comminuted meat raw material is carried out, f) final comminution (9) of the dried, heat-treated, preliminarily comminuted meat raw material is carried out, wherein in step d) a freeze-dryer with direct removal of water vapor by means of pumps is used, wherein step e) is carried out for at least 2h at a pressure in the range from approximately 0.4 mbar to approximately 0.5 mbar and at a product temperature of at least 72°C, and step f) comprises sieving the comminuted meat raw material through a sieve with a size of at least 120 mesh. The present invention also relates to a monoprotein nutritional product and the use of a monoprotein nutritional product.
