A flow system and a flow arrangement for flowing a building material in a building field of a manufacturing device for additive manufacturing includes an outer flow guide having an opening connectable to a gas discharge for discharging gas from a process chamber of the device, and a second flow opening connectable to a gas supply for supplying gas into the process chamber, the outer flow guide and a central flow guide are outside the building field, the building field extends radially from a building field recess not usable for manufacturing, wherein the outer flow guide is outside of the building field, and the central flow guide is in a central building field recess region, which is arranged outside in an inward radial direction of the building field, to generate gas flow running in radial flow direction over the building field.

Radial flow over a construction area

The invention relates to a method for the additive manufacturing of at least one three-dimensional object () by means of a system comprising a coating unit () and at least two irradiation units (), the irradiation areas of which partially overlap or are adjacent to each other, wherein the irradiation areas are adapted so that a total irradiation period for selectively solidifying one or more layers of applied build-up material () is minimised as required. The invention further relates to a system for additive manufacturing of three-dimensional objects and a computer-readable storage medium.

Additive manufacturing method and system

A method for the additive manufacture of at least one three-dimensional object by means of a system, wherein a coating unit is moved onward through any number of segments and/or subsegments such that the coating unit performs at least one idle run. A system for the additive manufacture of three-dimensional objects, and a computer-readable storage medium are also disclosed.

Method for additive manufacture, and system

The invention relates to a method for additively manufacturing at least one three-dimensional object () by means of a system, wherein a coating unit () is stopped in a segment (A; B; C; D) and/or one of its sub-segments (A; A; B; B; C; C; D; D) as a parking segment. Furthermore, the invention relates to a system for additive manufacturing of three-dimensional objects and a computer-readable storage medium.

Process for additive manufacturing and system

An apparatus for manufacturing a three-dimensional object by a layer-by-layer solidification of building material at the points corresponding to the cross-section of the object to be manufactured in a respective layer. The apparatus includes a process chamber in which the object is to be built up layer by layer by selectively solidifying layers of a building material in a build area, a gas supply device, and a recirculating air filter device, wherein the apparatus comprises a pressure stabilization device configured to keep the pressure in the process chamber substantially constant.
