Raw material are put into 3D printer, are printed；S3. obtained printed product is made annealing treatment.
By step S3, the printed product being molded in step s 2 carries out each in high-temperature process, and then removal process printed product
Internal stress between individual composition so that the energy reduction inside printed product, effectively prevents finished product from splitting in use
Situations such as seam or fracture.
2. the 3D printing method that the present invention is provided, in the step S2, comprises the following steps：Raw material are heated
Processing so that raw material exist in liquid form；Liquid starting material is subjected to spraying shape in 3D printer along bob-weight force direction
Into sublayer, after after raw material cooling, the spraying operation of next sublayer is carried out；Calculate outer rim tangent line and the gravity side of adjacent two sublayer
Angle α between, if α>35 °, then the size of sublayer is adjusted, to reduce α size.
When the angle between the outer rim tangent line and gravity direction of adjacent two sublayer is excessive, printed product generally in stress not
Stable state, once stress, it is easy to occur damaged.By controlling α size, the stress of printed product can be concentrated on to weight
On force direction, mechanical stability is effectively increased.It can prevent that printed product caves in use.
