Forming part with an inclined surface and its forming method

A method of forming a forming part with an inclined surface, the inclined surface used for forming the forming part with the inclined surface, the inclined surface is provided with an angle of inclination, the angle of inclination is an angle defined between the inclined surface and a forming base plate, the angle between the inclined surface and the forming base plate is an acute angle,

• the method comprising:
• obtaining a model of the part to be formed, wherein the model is provided with at least one inclined surface,
• performing a layer separating and slicing process on the model along a direction perpendicular to a deposition direction, thereby forming a plurality of forming layers;
• and
• performing scanning path planning on each forming layer of the plurality of forming layers, wherein the scanning path, after planning comprises an inner filling scanning path and a frame scanning path located on an outer periphery of the inner filling scanning path,
• wherein, in a plurality of forming layers forming the inclined surface, at least one layer to be formed has a suspended area protruding from a layer already formed and a non-suspended area, the frame scanning path comprises, a first path and a second path, the first path corresponds to the non-suspended area and the second path corresponds to the suspended area;
• based on the size of the angle of inclination, setting first process parameters for the first path and setting second process parameters for the second path;
• and
• using a laser melting deposition technique, printing the forming part with the inclined surface, layer by layer based on the set first and second process parameters for the first and second paths, respectively;
• wherein an energy density in the first process parameters is smaller than an energy density in the second process parameters.
