It rises, the second closure tip does not block the second port, and the second device of rotation driving drives secondary conveying screw rod by the original of thawing
Material conveying downwards passes sequentially through fourth lane, Five-channel, the 6th channel and the outflow of the 7th channel, and pads and flowed out in third channel
Raw material below；Heating element pair second is heated far from side wall, so that the heating inclined-plane of lower end is had higher temperature, simultaneously
Heating element further heats the raw material in secondary print head, keeps the temperature of the raw material in secondary print head and mobility high
In the temperature and mobility of the raw material in main print head, i.e. the temperature and mobility of the raw material of the 7th channel outflow are above third
The temperature and mobility of the raw material of channel outflow, in print procedure, heating inclined-plane and the lower layer slightly printable layer of cooled and solidified
Contact, can be such that the upper surface of lower layer's printable layer melts, the raw material that the raw material pad that subsequent 7th channel is flowed out is flowed out in third channel
Between lower layer's printable layer of surface thawing, the raw material of the 7th channel outflow plays the role of the original glued, third channel is flowed out
Material and lower layer's printable layer natural fusion are integral, make to be not in apparent engagement between upper layer printable layer and lower layer's printable layer
Face, the engagement between adjacent print layer is more secured, while also ensuring the raw material in the third channel of main print head as shape
The properties such as the mobility at the main material of printout are constant, do not change the design parameters such as main material initial flow, and then really
It protects printout and is less prone to the case where deformation etc. influences quality in print procedure.When printing is completed, the first lifting driving
Device drives main conveying screw rod that the first closure tip is made to block the first port downwards, the secondary conveying of the second lifting drive driving
Screw rod makes downwards the second closure tip block the second port.Third channel, lower end share common sidewalls, the 7th channel and heating inclined-plane
Become smaller successively with the angle of horizontal plane, this structure can be such that main discharging gate and secondary discharging gate from top to bottom increasingly gathers, and be more convenient for
The raw material of third channel outflow is contacted and is combined with the raw material that the 7th channel is flowed out, and the angle of third channel and horizontal plane is
15-30 °, the raw material that the setting at this inclination angle is more convenient in third channel is flowed out and is laid on the raw material of the 7th channel outflow, is added
The angle of hot inclined-plane and horizontal plane is 5-15 °, the setting at this inclination angle be more convenient for heating inclined-plane take advantage of a situation with lower layer printable layer contact and
Effective heating surface (area) (HS is sufficiently large, the thawing for lower layer's printable layer upper surface of being more convenient for.Compared with prior art, product one of the invention
The three-dimensional printer that body combines, the integral type that can carry out melting completely formula to adjacent printable layer engage, and printout is whole
Property it is strong and more securely, it is highly practical.
