Abstract

The invention relates to the technical field of selective laser melting metal 3D printing, in particular to cuboid-shaped 3D printing equipment and a 3D printer. The cuboid-shaped 3D printing equipment comprises construction-forming device and a powder supplying system. A powder laying device is used for laying metal powder in a powder feeding device on an operation platform in a rolling-type powder laying mode. A powder flattening piece driving mechanism is connected with a powder flattening piece and used for driving the powder flattening piece to move on the operation platform in a reciprocating mode so as to flatten the metal powder on the operation platform. The powder flattening piece driving mechanism is electrically connected with a control system of the 3D printer. The power laying device lays the metal powder on the operation platform in a rolling-type mode, the powder flattening device flattens the metal powder on the operation platform, and accordingly the flatness of a metal powder layer on the operation platform is improved, the density and surface smooth finish of a component can be improved effectively, and the machining condition of a large-size cuboid-shaped component with the forming length being larger than or equal to 3 m is met.

Description

technical field [0001] The invention relates to the technical field of 3D printing of laser selective melting metal, in particular to a cuboid 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 melting, laser curing, and laser cladding. , using special software to slice and reduce the dimensionality of CAD three-dimensional configuration objects, and then print the object layer by layer is a new technology that is rapidly developing in the manufacturing industry. The Three Industrial Revolutions" is called one of the important symbols of the third industrial revolution. [0003] Laser selective melting metal 3D printing technology uses high-energy-density laser beams to scan under the control of computer programs, selectively melts the pre-laid metal powder layer...
