Abstract: An additive manufacturing system, in particular a 3D printer, including a bottom element. The bottom element includes at least one funnel and/or air outlet, wherein at least one sieve and/or grid element is arranged in the area of the funnel and a plate element is arranged opposite the sieve.

Abstract: The present invention relates to a fluid supply system for a 3D printer including a fluid pressure generating device for generating a pressurized fluid flow and with a fluid heating device for heating the fluid flow, wherein the 3D printer has at least one construction chamber which is delimited by a construction chamber with respect to the surroundings of the 3D printer and is sealed in a fluid-tight manner, wherein the fluid pressure generating device, the fluid heating device and the construction chamber housing are in fluid connect ion, whereby the fluid flow can flow through the construction chamber, and wherein the fluid pressure generating device, the fluid heating device and the construction chamber housing define a closed fluid circuit for the fluid flow which is heated by the fluid heating device before entry into the construction chamber.

Abstract: The present disclosure relates to a positioning system for an additive manufacturing system, in particular for a 3D printer, the positioning system being a positioning system for positioning a print head, wherein the positioning system allows movements in several degrees of freedom and the positioning system is of two-part design such that a part of the degrees of freedom is made possible by a first part of the positioning system and a further part is made possible by a second part of the positioning system. The present disclosure further relates to an additive manufacturing system, in particular a 3D printer, comprising at least one positioning system.

Abstract: The present disclosure relates to a print head for an additive manufacturing system, in particular for a 3D printer, comprising at least one temperature control element, in particular a cooling element, which is arranged adjacent to the print head. The present disclosure further relates to an additive manufacturing system, in particular a 3D printer, comprising at least one print head.
