摘要： Some embodiments relate to a heat transfer device for additive manufacturing to be used inside a working chamber in an environment with an atmosphere of an inert gas (for example nitrogen, argon, etc). The device can include multiple independent laser sources and an array of LED diodes designed to convey the electromagnetic radiation in the pre-established work area.

摘要： A multi-laser system for additive manufacturing can be used inside a working chamber in an environment with an atmosphere of an inert gas, consisting of multiple laser sources and a plurality of optical and/or optical systems scanning necessary to generate and convey the electromagnetic radiation beams within the predetermined processing sectors in which it is possible to remove the fumes and/or pollutants deriving from the selective powder melting process as close as possible to the melted layer or layer and introduce in the same chamber the process gases necessary for the processing of powder bed fusion or powder bed in a localized manner.
