Description of the drawings
Fig. 1 is the structural schematic diagram of the rotary 3D printer of the utility model.
Wherein：1- prints receiving platform, 2- print heads, 3- material supplying devices, 4-X sliding rails, 5-Y sliding rails, 6-Z sliding rails
Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and examples.
Embodiment 1：
The present embodiment provides a kind of wire drawing type 3D printers based on wire drawing material, can realize the quick of micron scale construction
High quality is molded 3D printing.
As shown in Figure 1, the wire drawing type 3D printer includes：Gearshift, material supplying device 3 print receiving platform 1 and beat
Print head 2.
Material supplying device 3 is that material barrel is mounted on going out for material supplying device 3 for providing printed material, print head 2
Material mouth, printed material main body be can wire-drawing shape material, through stretching draw after can form micron order filament.Due to using wire drawing
Formula printed material is provided on the print head to ensure that the printed material for being drawn as filament can be disconnected reliably for that will stretch drawing
The filament of filament cut-out cut off structure, thus print head can uninterruptedly continuously print, and also can cut off structure in filament matching
Under conjunction, discontinuous printing.
Printing receiving platform 1 is used to receive printed material to form required stereochemical structure.
To print 1 place plane of receiving platform as X/Y plane, it is Z-direction perpendicular to the direction of printing 1 place plane of receiving platform, builds
Vertical three-dimensional system of coordinate.Gearshift for drive material supplying device 3 carry out X to, Y-direction, Z-direction linear motion, specifically include along X
To X sliding rails 4, the Y sliding rails 5 along Y-direction and the Z sliding rails 6 along Z-direction, three sliding rails independently drive by three motors respectively.In displacement
Under the drive of device, short distance fast offset can occur for print head, to which filament is stretched into printed material drawing in print procedure
After spray printing receiving platform on.
Printed material need to be drawn when due to printing and stretch into filament, to avoid air flowing from blowing filament, lead to filament
It disconnects or mobile, print procedure is completed in closed environment.
Print procedure is accurately controlled to realize, the motor by control unit control for driving three sliding rails, from
And straight-line displacement stroke and velocity of displacement of the control material barrel on three sliding rails.To ensure print head short distance fast bit
It moves, it is pre-set according to the relationship between acceleration distance and printed material wire drawing line weight in the control unit of gearshift
Acceleration distance continues the displacement completion printing that remains a constant speed after short distance accelerates displacement wire drawing；On the other hand, it is received in printing
Printed material is set in platform and initially accumulates position and excess stock recovery part.
The above-mentioned 3D printer based on wire drawing material can realize the fast and high quality molding 3D printing of micron scale construction, can
Micron order lines or any micron-sized biology or abiotic micro-structure are printed, is suitable for printing various based on micron order
The biological or inanimate stereochemical structure of lines.
