Abstract: A solution for monitoring the manufacturing of items with a 3D printer is presented. The solution comprises detecting (302) initiation of a manufacturing process where a 3D printer is used to manufacture an item; controlling (306) one or more sensors to obtain first information from the input materials to be utilised by the 3D printer during the manufacturing process; controlling (308) one or more sensors to obtain second information the 3D printer and the item being produced by the 3D printer during the manufacturing process; controlling (310) one or more sensors to obtain third information the item after the manufacturing process; storing (312) the first, second and third information; creating (314) from the first, second and third information an identification for the manufactured item.

Abstract: A method of additively manufacturing or repairing a part includes selecting a powder bed from one of a plurality of available powder beds, positioning a powdered metal within a space defined by the powder bed, selecting an energy source from one of a plurality of available energy sources, and selecting a robot from one of a plurality of available robots. The method also includes generating a 3-D model of the part within a design system and directly initiating the manufacture of the part using the selected powder bed, energy source, and robot from within the design system with operating instructions in G-Code or 3MF machine code language.

Abstract: A controller for three-dimensional laser beam machine having a head structure in which the machining point is unchangeable even when the rotation axis and posture axis are rotated, wherein the end position and posture of the nozzle are taught, and the machining is effected according to the teaching. The control is such that the nozzle-direction vector is calculated from the current angles of the rotation axis (14) and posture axis (16), the angle by which the posture axis (16) changes for a certain time is calculated, the angle by which the rotation axis (14) is rotated according to a change of the angle of the posture axis (16) in such a way that the X and Y directions of the nozzle-direction vector is kept unchanged, and the rotation axis (14) is made to rotate by the calculated angle.
