I.e. 3D printing forming method of the invention uses a kind of forming method of decanter type, in print procedure, with life
Into the increase of thing, base station can settle into liquid bath, so as to be stepped down for newest one layer of part to be formed.So print repeatedly more
Layer product, you can form the shape of solid, therefore flat shape can not only be printed using sedimentation, solid can also be printed
Shape.
In certain embodiments, the first printhead is not immersed in liquid bath, therefore by controlling the lifting of base station so that first
Printhead discharges the first raw material to the liquid level of the second raw material.It can so cause the first raw material in the very first time being released
Just contacted with the second raw material, avoid the first raw material from spreading the problem of causing molding effect bad or even can not being molded.
And in further embodiments, the first printhead is immersed in liquid bath, i.e., the first raw material is released the rear very first time just
Can be with the second raw material contact moudling.In such an embodiment, base station can be without lifting, and uses traditional 3D printing control
Method processed, the motion of the first printhead is individually controlled, realizes stereo shaping.
Preferably, the 3rd raw material is discharged by the second printhead, wherein the second printhead is accordingly set with the first printhead
Put.
As shown in figure 1, the second printhead 52 can discharge the 3rd raw material, the 3rd raw material can be a kind of additive, such as
Dyestuff or drug ingedient etc., the 3rd raw material is added into the finished product of product composition, to realize various effects.
For example, when printing facial mask, drug ingedient can be added to the predetermined portions of facial mask by the second printhead 52, carried
The effect of high facial mask.
In further embodiments, printing equipment can be not provided with liquid bath, but former by the second printhead release second
Expect to mix with the first raw material of the first printhead release, and product is formed on base station.
