公开了一种用于使3D打印操作能够与通过使用颗粒状原材料生产长丝同时进行的装置。 根据本发明的实施方式，原料的引入和丝的形成可以在一个装置中实现，并且用于制造丝的颗粒（原材料）直接引入而不使用应用于3D打印机的丝， 可以制造直接灯丝而不需要单独的灯丝制造工作，并且可以执行3D实现工作。

Using a raw material of the pellets at the same time as the manufacturing of the filament, the device that allows to implement a 3D printing operation is started. According to an embodiment of the invention, a bar that can be implemented in the formation of the raw material input as the filament in a single unit, without the use of a filament applied to the 3D printer, by introducing the pellets (starting material) for producing the filament directly, manufacturing filaments directly without separate manufacturing of filament operations and can perform 3D solid object implementation work.
