3D printing sintering device

Abstract

The invention discloses a 3D printing sintering device, which includes a casing and a sliding door. The casing is provided with a sintering furnace, an electric unit, a strong cooling unit, a vacuum unit and a cooling water unit. The sintering furnace includes a furnace body and a furnace door, an electromagnetic lock is installed between the furnace body and the furnace door. The electric unit includes a DC power supply. The cooling water unit can cool the electric unit and the sintering furnace. The electric unit is connected to the heating body. The heating body can heat the sealed box. Thesealed box has a box door. The box door is opposite to the furnace door, the furnace door is connected with the sliding door, and the sealing box is connected with a dewaxing pipeline. The 3D printing sintering device of the invention has a compact structure and a small floor area. The vacuum unit can evacuate the cavity of the sintering furnace. At the same time, the sintering furnace is provided with a thermal insulation structure layer, a sealed box and a heating body. The heating body can heat the sealed box, and the heat insulation structure layer can reduce the heat exchange between thesealed box and the external environment, and can be widely used in laboratories, research and development departments and other institutions.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D printing sintering device. Background technique [0002] In recent years, metal parts that have been 3D printed using the binderjetting process have become more and more popular in the manufacturing industry. Compared with the traditional metal casting process, the cycle time is long and the mold manufacturing cost is high. In many cases, it cannot meet the needs of rapid iteration of manufactured products and the needs of cost control. The binder jet metal 3D printing technology can quickly manufacture metal parts in a short time, which significantly shortens the design and manufacturing cycle, especially in the rapid manufacture of stainless steel, cobalt-based, nickel-based, aluminum, titanium alloys and other metal parts. has significant advantages. The working principle of binder jetting 3D printing technology is to spread a layer of powder first, and then use the...
