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. Pierwszy wlot (24) gazu osłonowego lub/i drugi wlot (26) gazu osłonowego są przeznaczone do wytwarzania profilu przepływu, w którym w odniesieniu do kierunku poprzecznego względem głównego kierunku poprzecznego w bocznych, a zwłaszcza zewnętrznych obszarach płyty konstrukcyjnej wytwarzana jest większa prędkość przepływu niż w obszarze centralnym płyty konstrukcyjnej, aby utworzyć boczny strumień prowadzący.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. The first shielding gas inlet (24) or / and the second shielding gas inlet (26) are intended for producing a flow profile in which, with respect to the transverse direction relative to the main transverse direction, a greater flow velocity is generated in the lateral and especially outer regions of the construction plate in the central area of the building plate to create a lateral guide stream.
