Abstract
The invention relates to the technical field of selective laser molten metal 3D printing and particularly relates to cylinder-shaped 3D printing equipment and a 3D printer. The cylinder-shaped 3D printing equipment comprises a powder supply system and an establishing and forming device; the establishing and forming device comprises a ring-shaped workbench; the powder supply system comprises a powder laying device and a powder feeding device; the powder laying device comprises a powder laying piece and a powder laying drive mechanism; the powder laying piece is round; the diameter of the powder laying piece can be changed; and the powder feeding device comprises a powder feeding cylinder, the cross section of the powder feeding cylinder is of a ring shape, and the powder feeding cylinder is arranged outside the workbench in an enclosing manner. The workbench is set to be of a ring shape, metal powder on the workbench forms a ring-shaped working face, the diameter of the workbench can be set by a user according to the diameter size of a forming component, the problem that the forming size is limited is solved, a hollow cylinder-shaped component with a large diameter can be formed, and particularly, the hollow cylinder-shaped component with the diameter being two meters or above can be formed.
Description
technical field [0001] The invention relates to the technical field of laser selective melting metal 3D printing, in particular to a cylindrical 3D printing equipment and a 3D printer. Background technique [0002] Additive manufacturing 3D printing technology is based on digital model files (CAD), using powdered metal, PVC, resin, fiber and other materials, through fusion deposition, laser sintering, laser selective melting, laser curing, laser cladding, etc. This is a high-end manufacturing technology that uses special software to construct CAD 3D graphics to shape objects, slices to reduce dimensionality, and then prints structured objects layer by layer. It is an emerging technology that is rapidly developing in the manufacturing industry. "The magazine "The Third Industrial Revolution" is called one of the important symbols of the third industrial revolution. [0003] The powder supply system, construction room and work room of the laser selective melting 3D printer in...
