Method for manufacturing a component from polyhedra having polyhedron edges which are formed from a semi-finished product, component and production facility. The method has the steps of: subdividing the component to be produced into a net of polyhedra, consisting of polyhedron edges, which are interconnected at the polyhedron node points thereof to form the net; providing a semi-finished product provision device, which provides the semi-finished product; providing a supply guide device for supplying the semi-finished product from the semi-finished product provision device and positioning the semi-finished product; providing a cutting and welding device or a welding device for welding and a cutting device for cutting to size the semi-finished product; supplying the semi-finished product by way of the supply device; constructing the net of polyhedra by positioning the supplied semi-finished product in the position of the polyhedron edge to be formed at the associated polyhedron node point of the net of polyhedra in each case, and fixing the semi-finished product at the polyhedron node point by welding.

In a three-dimensional printing method example, a liquid functional agent is selectively applied. The liquid functional agent includes an alloying agent. A metallic build material is applied. The liquid functional agent is selectively applied before the metallic build material, after the metallic build material, or both before and after the metallic build material. The liquid functional agent patterns the metallic build material to form a composite layer. At least some of the metallic build material is exposed to energy to melt the at least some of the metallic build material to form a layer. Upon contact or after energy exposure, the alloying agent and the build material alter a composition of the composite layer.

A three-dimensional shaping device includes: a discharge unit configured to discharge a shaping material; a weight measuring unit configured to measure a weight of the shaping material discharged from the discharge unit; and a control unit configured to control the discharge unit and the weight measuring unit to shape a three-dimensional shaped object by stacking layers of the shaping material in a shaping region of a stage, in which the control unit is configured to control the weight measuring unit to measure the weight of the shaping material discharged from the discharge unit, determine whether a predetermined amount of the shaping material is discharged from the discharge unit based on the weight measured by the weight measuring unit, and when it is determined that the predetermined amount of the shaping material is not discharged, control the discharge unit so that the predetermined amount of the shaping material is discharged from the discharge unit.
