Systems, devices, and methods for additive manufacturing are provided that allow for components being manufactured to be assessed during the printing process. As a result, changes to a print plan can be considered, made, and implemented during the printing process. More particularly, in exemplary embodiments, a spectrometer is operated while a component is being printed to measure one or more parameters associated with one or more layers of the component being printed. The measured parameter(s) are then relied upon to determine if any changes are needed to the way printing is occurring, and if such changes are desirable, the system is able to implement such changes during the printing process. By way of non-limiting examples, printed material in one or more layers may be reheated to alter the printed component, such as to remove defects identified by the spectrometer data. A variety of systems, devices, and methods for performing real-time sensing and control of an additive manufacturing process are also provided.

Various embodiments of the teachings herein include a method for determining a radiation intensity and/or a wavelength of a process light, wherein the melt pool underlying the process light can be generated by irradiating a metal material with an energy beam along a path, wherein the energy beam can be moved in accordance with a power profile along the path. The method may include: providing a power profile for a section of the path as an input variable for a machine learning model; training the model using historical and/or synthetic power profiles and associated historical or synthetic radiation intensities and/or wavelengths of the process light for the metal material; and determining the radiation intensity and/or the wavelength of the process light as an output variable of the model.

Laser processing head (20) of the present disclosure includes housing (30), transparent protector (40), and temperature sensor (70). Housing (30) includes an optical path of processing laser light (LB). Transparent protector (40) is detachably fixed to housing (30), passes processing laser light (LB), and suppresses dust of work material (W) entering into housing (30). Here, the dust is generated from the work material (W) irradiated with processing laser light (LB). Temperature sensor (70) detects the temperature of transparent protector (40).

A double-sided machining laser machine tool is provided for machining a workpiece having opposite first and second machining surfaces. The machine tool includes a laser machining apparatus and a mechanical arm. The laser machining apparatus includes a laser source, a light guiding-and-focusing lens assembly, a three-axis moving stage, an optical inspection device, and a control device. The control device drives the three-axis moving stage moving the workpiece to a machining horizontal coordinate and a machining altitude according to a current horizontal coordinate and a current altitude of the work piece. The control device drives the laser source and the light guiding-and-focusing lens assembly focusing the laser light to the first machining surface. The mechanical arm is controlled by the control device. When the machining of the first machining surface is finished, the mechanical arm flips over the workpiece to allow the laser machining apparatus to machine the second machining surface.

The present disclosure relates to a method for creating a job from a central operator software for various laser types, in particular a laser plotter or a galvo marking laser, for engraving, marking, lettering and/or cutting a preferably flat workpiece, in which at least one beam source in the form of a laser is used in a housing of the laser device for processing the workpiece. The workpiece is deposited in a defined manner in a processing chamber on a processing table and a laser beam emitted by the beam source is sent via deflecting elements to at least one focusing unit, by which the laser beam is deflected in the direction of the workpiece and positioned accordingly. The control is effected via control software running in a control unit, in which software a so-called job is processed.
