Background technology
The 3D printer difference maximum with conventional printer is that " ink " that it is used is raw material true, heap
The form of folded thin layer has varied, available for the medium wide variety of printing, from various plastics to metal, ceramics and rubber
Gelatin substance.Some printers can also combine different medium, and one, the object that order is printed is hard and other end is soft.
Some 3D printers use the mode of " ink-jet ".Printer head is used by one layer of very thin liquid plastic material
It is sprayed on mold pallet, this coating is then placed in being handled under ultraviolet.Mold pallet declines minimum distance afterwards,
So that next layer of stacking is come up.
Use one kind also is called the technology of " fused deposition modeling ", and whole flow process is that plastics are melted in shower nozzle, Ran Houtong
The mode for crossing depositing plastic material fiber just forms thin layer.
Also some systems are called the technology of " laser sintered " using one kind, and print media is used as using powder particle.Powder
Particulate is sprayed one layer of very thin powder bed of formation on mold pallet, and then founding is glued into designated shape by the liquid sprayed
Mixture is solidified.
What is had is then to utilize the electron stream fusing powder particle in vacuum, and complexity as hole and cantilever is included when running into
Addition gel or other materials are accomplished by during structure, in medium to support or for taking up space to provide.This amount of powder is not
Can be by founding, it is last that only need to fall supporter with water or gas washout just can form hole.
But, above-mentioned used consumptive material is pasty state or solid powder, easily blocks the nozzle of shower nozzle, is influenceed
The effect of printing.
