Further, the air inlet end of the air blowing shell is provided with three air inlet openings, and air inlet connecting pipes are fixedly mounted at ports of the three air inlet openings.
Further, the air inlet of the air inlet connecting pipe is a standard phi 64 chuck joint.
Further, the air blowing system is made of stainless steel materials through 3D printing.
Furthermore, the apertures of the air inlet holes and the air outlet holes which are arranged in multiple rows are sequentially enlarged from top to bottom to be divided into small holes, medium holes and large holes.
Further, the insufflation system is made of 316L stainless steel.
Further, the cross-sectional areas of the gas inlet holes and the gas outlet holes are the same, and the resistance of the gas passing through the gas pipeline is the same.
A3D printer comprises the air blowing system of any one of the above items.
The invention has the beneficial effects that: according to the blowing system of the 3D printer, the molten slag can be sucked and blown out of the cabin body in time and cannot fall onto the surface of a printed workpiece by changing the distribution state of the airflow. Can in time clear away the slag that produces in the printing process, print the density of work piece and promote, intensity obviously increases, guarantees the density that 3D printed the work piece.
