[0045] In the graphite type 3D printing system based on titanium and titanium alloy castings, the printing platform 1 is a horizontal swing platform, such as figure 2 As shown, it includes a working ...

[0049] A kind of printing method based on the 3D printing system of titanium and titanium alloy casting graphite type described in above-mentioned embodiment 1 and embodiment 2, comprises the following steps:

[0050] Step 1, three-dimensional modeling: according to the shape and size of the titanium and titanium alloy castings to be cast, design the shape of the graphite type, the parting surface and the casting port, etc.; make the designed three-dimensional model of the graphite type in the computer, and place the The three-dimensional model diagram is subjected to two-dimensional slice processing;

[0051] Step 2, prepare printing materials: prepare graphite powder or graphite powder and superfine powder blast furnace slag and / or high titanium slag powder according to the ratio of 10:1 to prepare powdered graphite material, the selection of this material reduces the material cost of the mold; Quartz sand and sodium oxide are prepared in proportion to obtain a sodium silica...
