3D POWDER SINTERING TYPE UNIFORM POWDER APPLICATION DEVICE FOR METAL 3D PRINTER AND UNIFORM POWDER APPLICATION METHOD USING THE SAME

摘要

One embodiment of the present invention provides a uniform powder coating device for a powder sintering type 3D metal printer, which comprises a front blade, a rear blade, and a mesh to form synthetic resin, ceramic, and metal powder having a particle with an ununiform shape so as to form a uniform layer. According to one embodiment of the present invention, the uniform powder coating device for a powder sintering type 3D metal printer coats powder by three times to coat mixed powder. To increase powder coating uniformity, the uniform powder coating device coats first powder with the front blade, allows fine powder among the powder getting on the front blade to pass through the mesh by using vibration in order to arrange the ununiform powder coating occurring in the first powder coating so as to stack the fine powder on the first coated powder, and removes excessive powder with the rear blade.
