Description
Technical field
The present invention relates to a kind of 3D print system.
Background technology
3D prints and both need not paper using, it is not required that with black, but design a model as source with Computerized three-dimensional, by soft
Part is layered discrete and numerical control molding system, utilizes the mode such as laser beam, hot melt nozzle by metal dust, ceramic powders, plastics, thin
The special materials such as born of the same parents' tissue are successively piled up and are cohered, and final superposition molding produces entity products.Its advantage is to be greatly saved
Production piece Production Time, and the product that moulding is complicated " can be printed ".
Existing 3D based on FDM (Fused Deposition Modeling technique Fused Deposition Modeling) technology prints system
Based on unit, printhead or the two print head arrangement of constant spacing as unification, industrial 3D printer many uses SLA forming technique.
Fusion sediment (FDM) is sometimes otherwise known as fuse deposition, and thread heat-fusible materials carries out heating and melting by it, by with
Material extruded by the extruder of minute nozzle.Shower nozzle can move along X, Y, Z axis direction by workbench relatively, melted silk
Material can be bonded together with preceding layer material after being extruded immediately.After layer of material deposition, shower nozzle is pressed pre-relative to workbench along Z axis
Fixed increment rises a thickness, then repeats above step until the complete molding of workpiece.
The 3D printer of currently used FDM mostly is single head monochrome and prints, and along with the raising of printing precision, the time-write interval is several
What level rises.3D colour print is typically by using special printhead and being equipped with special special consumptive material and realize, and equipment becomes
This is higher.3D prints and mostly is mono-material printing, when object has multiple requirement to material, is typically all by by multiple unlike materials
Object be mutually combined and meet, need to additionally design the combinative structure between each object, add redundant structure and operation, improve
Design difficulty and cost.The 3D printer of single head, after consumptive material runs out of, it is necessary to break-off is to change consumptive material, and some prints
Machine even can cause printing unsuccessfully because consumptive material is finished.Common 3D printer is of a great variety, and function is the most different, but all cannot
Carry out function upgrading.One printer, the when of producing, its function determines constant the most substantially, at most carries out software
The optimization of aspect.If user needs other functions, can only select to buy another printer, the printer before bought just may be used
Idle article can have been become.
Therefore, there is inefficiency in existing 3D printer, it is impossible to uses while realizing multiple types color, material,
Cannot be carried out the shortcoming that function upgrading production capacity expands, practicality has to be strengthened.
Summary of the invention

The technical program is compared with background technology, and it has the advantage that
The present invention can carry out structure function upgrading according to actual needs and production capacity expands.By add print module number and
Printing the mode of number of print heads on module, the function of a 3D printer and production capacity can be by most basic single head monochrome list things
Body printing escalates into the polychrome many objects of many materials and prints in batch, to meet the different demands of different user different times.Specifically
Ground:
1. the present invention can use multiple printhead to print an object to be effectively improved printing effect simultaneously.Print each
Layer time, distribute respective print area give each printhead, make multiple printhead cooperation jointly complete the printing of an object.When
So, it is possible to multiple printheads print object respectively, printing batch is made to carry out, it is provided that printing effect.
2. the present invention can use the consumptive material of different colours to carry out colour print.During printing, beat multiple as required
Use the consumptive material of different colours to print same object on print head, enable the different parts of same object to present difference
Color.Exempt follow-up colouring operation.
3. the present invention can use the printhead of unlike material consumptive material to carry out the printing of many materials.During printing, as required
Multiple printheads use the consumptive material of unlike material to print same object, make the different parts of object have different spies

Connect one-body molded, improve product specification, avoid the waste of material, the number of components reducing product and production process number, be conducive to carrying
The added value of high product also reduces the production cost of product.
4. the present invention can uninterruptedly print, and will not interrupt because consumptive material used by printhead is finished printing.Printing
Before beginning, use corresponding identical consumptive material to standby printhead depending on the consumptive material surplus of the printhead of preparation.When work
Consumptive material used by printhead is less than time a certain amount of, and standby printhead starts to enable preheating.Complete can make in the preheating of standby printhead
Used time, the printhead of former work is replaced to continue print job.The printhead of former work quits work reset, waits consumptive material to be replaced.
Consumptive material can be made full use of, it is to avoid waste, ensure that print job is persistently carried out.
In the middle of 5.X shaft movement mechanism, connect seat and be in transmission connection with cross lead screw, compare tooth belt or tooth bar, it is possible to more
The effective degree of accuracy ensureing printing.Equally, in the middle of Y-axis motion, mounting seat is connected with longitudinal screw rod transmission, it is possible to more have
The degree of accuracy ensureing printing of effect.
6. connect seat, cross slide uses the mode of upper and lower cover structure to be fastened on screw mandrel, and mounting seat uses tiled configuration
Mode close and be buckled on leading screw slide bar, keep in repair, very convenient when changing.
7., when printing, use the printhead of relatively hand line nozzle when printing outline portion, protected by high-precision printing
Demonstrate,prove the fine of object surface；Printing the printhead of inner filling part timesharing use larger caliber nozzle, by low precision
Print and improve print speed.
