In, so as to avoid in print procedure, since material silk heats the phenomenon that fusing water boiling generates bubble, substantially improve increasing material
The print quality and effect of manufacturing equipment 100.
In conclusion increasing material manufacturing method provided by the invention have the following aspects the utility model has the advantages that
Increasing material manufacturing method provided by the invention, including installation part material silk and backing material silk, dry part material
Silk and backing material silk completely cut off part material silk and backing material silk with outside air respectively by heated drying system 160.
Finally start model printing.The increasing material manufacturing method is easy to operate, and dry hot-air is filled with material by heated drying system 160
In material conveying tube, the moisture removed in material silk can effectively prevent material so that material silk is constantly in dry hot-air
Expect that silk is contacted with external world's unlatching, avoids in print procedure due to the water boiling generation when melting of the moisture in material absorption air
The phenomenon that bubble, is effectively improved print quality, improves product qualification rate.Secondly, controlling entire increasing material system using control device 170
The printing operation of manufacturing apparatus 100, high-efficient, precisely, high degree of automation, intelligence degree are high for control.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the present invention can have various changes, combination and variation.All within the spirits and principles of the present invention, made
Any modification, equivalent substitution, improvement and etc. should all be included in the protection scope of the present invention.
