Abstract

Wynalazek dotyczy urządzenia do wytwarzania obiektów trójwymiarowych zawierającego: laser emitujący selektywną wiązkę laserową, obszar docelowy (31), gdzie wytwarzane są obiekty, środki dozowania proszku do obszaru roboczego, środki do przemieszczania wiązki laserowej i modulacji lasera selektywnego do spiekania proszku w określonych granicach warstwy proszku dostarczanego do wspomnianego obszaru docelowego (31), zespół sterujący dostosowany do przeprowadzania selektywnego spiekania w kolejnych warstwach proszku prowadzący do powstania obiektu trójwymiarowego, przy czym świeży proszek z obszaru roboczego do obszaru docelowego (31) drukowania przesuwany jest przez wałek (32), którego przynajmniej jeden z końców przymocowany jest do prowadnicy (33) charakteryzującego się tym, że przynajmniej na jednym z końców wałka (32) znajdują się wałki pomocnicze, a pomiędzy nimi przechodzi linka rozciągnięta wzdłuż prowadnicy (33) i przymocowana do przeciwległych ścianek urządzenia, przy czym linka ta umieszczona jest na wałku (32) i jest do niego dociskana przez dwa sąsiadujące wałki pomocnicze w taki sposób, że przy przesuwaniu wałka (32) powoduje jego ruch obrotowy w kierunku przeciwnym od jego ruchu liniowego.The invention relates to a device for producing three-dimensional objects comprising: a laser emitting a selective laser beam, a target area (31) where objects are produced, means for dispensing powder into the working area, means for moving the laser beam and modulation of a selective laser for sintering powder within defined boundaries of the powder layer of the control unit supplied to said target area (31) adapted to perform selective sintering in successive layers of powder leading to the creation of a three-dimensional object, whereby fresh powder from the working area to the printing target area (31) is moved through a roller (32), at least one of the ends is attached to a guide (33) characterized in that at least one of the ends of the shaft (32) has auxiliary rollers, and between them passes a cable stretched along the guide (33) and attached to the opposite device walls, where the cable is placed on the shaft (32) and is pressed against it by two adjacent auxiliary rollers in such a way that when the shaft (32) is moved, it causes its rotation in the direction opposite to its linear movement.
