The invention relates to a machining module for a device for producing a molded metal body (1) by means of an additively generative manufacturing process. A sheet, wire, or pulverulent metal-containing starting material (2) is melted and applied in layers, thereby forming the molded body (1). According to the invention, in addition to a material supply device (9), the machining module comprises a protective gas supply device (11), which has an outlet opening arranged annularly about the material supply device (9), and a fluid supply device (3) for supplying coolant (4), having one or more nozzles (10) which are arranged spatially adjacent to the material supply device (9) such that the surface of the molded body (1) can be supplied with the coolant (4) in points or in a partial manner directly adjacent to the melt bath at one position or along a curve, each of which can be specified in a variable manner.

An additive manufacturing system including a two-dimensional energy patterning system for imaging a powder bed is disclosed. Improved chamber designs, multiple chambers, powder handling and re-use systems, and powder characterization methods are disclosed.

A system for separating the front and back outer glass layer from the casing/body of electronic mobile devices and for cutting mobile device screen protector sheets by way of laser burning and cutting comprises a housing, such housing containing a laser; a mirror galvanometer; a safety chamber enclosure; a metal plate with internal glass sheet; a chamber with opening and closing lid, lid button and lid sensor; a control printed circuit board with processor; a power inlet; a power supply; and an on/off switch.

Systems and methods are disclosed relating to welding-type power supplies. In some examples, the power supplies may have no vents, which may help prevent environmental contaminants from entering the power supplies. Instead, the power supplies include one or more thermal interfaces configured to conduct heat generated by internal circuitry of the power supply from the interior of the power supply to an exterior of the power supply. Additionally, the thermal interface(s) may be configured for attachment to one or more exterior heat dissipating devices.

Sensor data generated by a sensor of a computer numerically controlled machine can be compared with a forecast. The forecast can include expected sensor data for the sensor, over a course of an execution plan for making a cut with a movable laser cutting head. The sensor data can be generated during execution of the execution plan. During execution of the execution plan, the sensor data can be monitored and a deviation of from the forecast can be detected. It can be determined, based on the detecting, that an anomalous condition of the computer numerically controlled machine has occurred. Based on the determining, an action can be performed.

A three-dimensional deposition device includes a deposition head provided with a powder jetting port and a light beam irradiation port to form a deposited body by the powder being melted and solidified; a shape measurement unit that measures a shape of the deposited body; a deposited body cooling unit that jets cooling gas to the deposited body to cool the deposited body; and a control unit. The control unit causes the shape measurement unit to measure the shape of the deposited body, determines whether to cool the deposited body based on a result of measuring the shape of the deposited body, and causes the deposited body cooling unit to jet the cooling gas to the deposited body to cool the deposited body in a case in which the cooling determination unit determines to cool the deposited body.

A method for additive production and a correspondingly produced component made of a powdery base material, includes the thermal pre-treatment of the base material at a first temperature of at least 800° C. under an inert gas atmosphere, wherein the first temperature and a duration of the pre-treatment are further selected such that no sintering process of the base material occurs, subsequent cooling of the base material, and additive construction of the component from the thermally pre-treated base material. A corresponding device is for the additive production.

Additive manufacturing can involve dispensing a powdered material to form a layer of a powder bed on a support surface of a build platform. A portion of the layer of the powder bed may be selectively melted or fused to form one or more temporary walls out of the fused portion of the layer of the powder bed to contain another portion of the layer of the powder bed on the build platform
