Abstract

Wynalazek dotyczy urządzenia (10) do wytwarzania addytywnego części, zwłaszcza do selektywnego stapiania laserowego, z komorą procesową (12), która jest otoczona obudową (14), umieszczoną w komorze procesowej (12), a zwłaszcza opuszczaną płytą konstrukcyjną (22), przy czym na płycie konstrukcyjnej (22) warstwowo formuje się wytwarzany przedmiot poprzez laserowe naświetlanie złoża proszkowego, co najmniej jednym pierwszym wlotem (24) gazu osłonowego, przez który gaz osłonowy wpływa laminarnie do komory procesowej (12), korzystnie zasadniczo równolegle do płyty konstrukcyjnej (22), co najmniej jednym drugim wlotem (26) gazu osłonowego, który jest umieszczony powyżej pierwszego wlotu (24) gazu osłonowego i jest przeznaczony do wytwarzania drugiego strumienia gazu osłonowego, aby utrzymać laminarny przepływ gazu osłonowego z pierwszego wlotu (24) gazu osłonowego w kierunku płyty konstrukcyjnej (22), co najmniej jednym urządzeniem odsysającym (28), które jest przeznaczone do odsysania wprowadzonego gazu osłonowego, przy czym wloty (24, 26) gazu osłonowego i urządzenie odsysające (28) są umieszczone w odniesieniu do płyty konstrukcyjnej (22) na przeciwległych stronach. Proponuje się, że w odniesieniu do kierunku poprzecznego względem głównego kierunku przepływu gazu osłonowego w bocznym, a zwłaszcza zewnętrznym obszarze płyty konstrukcyjnej (22) znajduje się co najmniej jedno urządzenie z dmuchawą do wytwarzania bocznego strumienia prowadzącego. Wynalazek dotyczy również sposobu wytwarzania addytywnego części z wykorzystaniem ww. urządzenia.The invention relates to a device (10) for the production of additive parts, especially for selective laser melting, with a process chamber (12) which is surrounded by a housing (14) located in the process chamber (12), and in particular a lowered construction plate (22), with what is formed on the construction plate (22) by the laser irradiation of the powder bed with at least one first shielding gas inlet (24) through which the shielding gas flows laminar into the process chamber (12), preferably substantially parallel to the construction plate (22) ), at least one second shielding gas inlet (26) which is located above the first shielding gas inlet (24) and is intended to produce a second shielding gas stream to maintain laminar shielding gas flow from the first shielding gas inlet (24) towards a construction plate (22), with at least one suction device (28), which e is intended to suck off the introduced shielding gas, wherein the shielding gas inlets (24, 26) and the suction device (28) are located relative to the construction plate (22) on opposite sides. It is proposed that with respect to the transverse direction relative to the main shielding gas flow direction in the lateral and especially the outer region of the building plate (22) there is at least one device with a blower for producing a lateral guide stream. The invention also relates to a method of producing an additive part using the above-mentioned devices.
