Preferably, the consumptive material that the present invention uses selects granular polyether-ether-ketone-PEEK, and polyether-ether-ketone is a kind of hypocrystalline
The special engineered material of aromatic thermoplastic possesses numerous excellent performances, itself high temperature resistant, nontoxic, light, intensity is high, resistance to
Burn into low friction has had widely in aerospace, automobile, energy field as a kind of high-performance special engineering plastics
Using especially having unique advantage in terms of micro-structured form, the printing of PEEK is more suitable for carrying out under low charging rate, energy
Enough utilization rates for utmostly improving consumptive material.
In use, the consumptive material of different colours can be transported in the sub-material chamber 78 from different feed pipes 74, institute is entered
The consumptive material stated in sub-material chamber 78 enters in the conveying channel 11 from the discharge port 781, moves to the feeding still further below
In chamber 14, by controlling control valve 75, the consumptive material for selecting suitable color is used.
The driving motor 10 drives the screw rod 9 to rotate, and the screw rod 9 squeezes and the consumptive material is pushed to move downward,
When consumptive material is moved downwardly in the hot melt chamber 23, being melted by the high-temperature heating of the heating device 2 is molten condition, finally quilt
The discharge head 5 squeezes out, for printing.
Typical FDM printer is mainly made of radiating block, trunnion, heat block, nozzle, print head using frictional force as
Power, the material that rear is not melted are pushed ahead, so that the material that leading portion is melted is squeezed out from nozzle, since throat inner radius is big
In consumptive material diameter, in printing not in time such as trunnion heat dissipation, the consumptive material of leading portion fusing can not only be squeezed out from nozzle, will also be in trunnion
Gap between consumptive material, which is formed, flows backwards, so that the frictional force between consumptive material and trunnion be made to increase, even results in material from trunnion
Rear end is overflowed, and not wire vent is caused, since what is relied on when consumptive material is squeezed out from nozzle is the forward thrust of the non-melted material in rear, with
The growth of print time, if the temperature of trunnion rear end reaches material glass temperature or more, consumptive material softening, forward thrust becomes
Small, then spinning amount reduces, and consumptive material squeezes out width and narrows, so that element precision reduces.Particularly with the high performance polymer such as PEEK,
One side material large viscosity, tolerable gap flows backwards distance and is inherently shorter than ABS, PLA, and material melting point is high in addition, nozzle
Generally at 350 DEG C or more, traditional radiating block heat dissipation is difficult to that trunnion rear end temperature is made to be reduced to material glass temperature print temperature
Therefore degree is hereinafter, usually there is " plug " phenomenon.
For the high-melting-points such as PEEK, high viscosity material, existing print head structure is unable to satisfy the cooling requirements of trunnion, no
The long-time for being able to achieve such material continuously finely prints, and needs to reduce trunnion temperature in time, improves in high temperature print procedure
Gap is flow backwards, to keep stable printing precision in continuous print procedure for a long time.
These are only the preferred embodiment of the present invention, is not intended to restrict the invention, for those skilled in the art
For member, the invention may be variously modified and varied.All within the spirits and principles of the present invention, it is made it is any modification,
Equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
