Realize the Quick-forming of part 3D solid.Do not needed in 3D printing technique manufacturing process complicated technique, do not need it is huge
Lathe, do not need numerous process flows, effectively reduce the complexity of manufacture, shorten the process-cycle of part,
It gradually promotes and applies and comes in the industrial production.
Although 3D printing technique have many advantages, such as it is above-mentioned, there are still many insufficient in industrial production application,
Middle comparison be typically a variety of 3D printing techniques need in the print procedure of part model to some hanging of model or
Tilt position and necessary support construction be set, just can guarantee product successfully " successively stacked " during 3D printing get up or
Prevent local excessive deformation, such as laser from choosing melting (SLM), resin Stereolithography (SLA), plastic molten melt deposition (FDM)
Deng.Although current such support construction can guarantee to print successfully or control deforms, need to remove after printing is complete
Often there is great limitation when these supports, be embodied in can not be economical removal support or removal difficulty is big, process
Complexity etc..It is capable of the support construction of quick, easy, economic removal after therefore, it is necessary to design a kind of 3D printing process,
To meet industrial low cost, high efficiency needs.
