Nozzle exit area control method with the nozzle component of 3D printing equipment.
Background technology
Biological 3D printing refers to the principle and method by 3D printing, and biomaterial (is included natural biologic material and conjunction
Become biomaterial or cell solution) print the three dimensional structure becoming design.Can be made using cell and biocompatible materialses
Biological prepared Chinese ink.When carrying out 3D printing, moved by programme-control nozzle component, nozzle component moves and will biological ink from its spout
Juice sprays, and biological prepared Chinese ink is built mathematical model printing shaping according to the three-dimensional of default target three dimensional structure.
With the development of biological 3D printing technique, to prepare the tube chamber shape such as artificial blood vessel biological tissue by 3D printing technique
Development Trend and the focus in biological 3D printing field are become.
Taking 3D blood vessel printer as a example.3D blood vessel printer is that a kind of biological 3D for printing tube cavity-like biological tissue beats
Print machine.3D blood vessel printer generally includes nozzle component, rotation bar assembly and this three big module of motion platform assembly.
Nozzle component is mainly used in discharging biological prepared Chinese ink in order.Rotation bar assembly mainly uses itself rotary motion and connects
Receive biological prepared Chinese ink and thereon generate lumen structure.Motion platform assembly is used for driving nozzle component and rotation bar assembly to produce
Relative displacement.
For 3D blood vessel printer, after biological prepared Chinese ink extrusion, generally only need to the axial movement along rotation bar assembly
The biological prepared Chinese ink that instils can generate reservation shape, and compared to other 3D printers,, in print procedure, nozzle component need not enter for it
The displacement of row Y direction.Just because of this, existing blood vessel printer generally will not be adjusted in the single displacement of Y direction design
Mechanism's (as guide rail, linear electric motors etc.).By one Y-axis adjustment structure of few setting, can be difficult with reduces cost, simplify control
Spend and make 3D printer complete machine structure more succinct.
Accurately print to realize and shape, the spout of nozzle component of 3D blood vessel printer is necessary with rotation bar assembly
There is higher synteny.Synteny is that the center of the spout of nozzle component is put down positioned at same XZ with the axis of rotation bar assembly
In face.But actual manufacture and assembling process in, the synteny of the spout of nozzle component and rotation bar assembly often it is difficult to ensure that
's.For example：The factors such as the deformed or bent, rigging error of workpiece itself manufacturing tolerance, material or line rail, all can have influence on two
The synteny of person.
In prior art, when the spout of nozzle component deviation with rotation bar assembly in Y direction position, common
Way is by way of increasing cushion block between nozzle component and motion platform assembly, Y direction position to be finely adjusted.
During realizing the present invention, designer finds, to adjust nozzle component by the way of increasing cushion block
Spout has following weak point with respect to rotation bar assembly in the position of Y direction：
Regulation process is loaded down with trivial details, operation inconvenience, and the factor producing gap is numerous, and the thickness of cushion block is difficult to select and determines, can
Can increase and decrease cushion block repeatedly and correction, need repeatedly to debug and measure checking, process is very complicated, adjustment operation and adaptability
Poor.Although in addition, adjust wasting time and energy, the accuracy of regulation is often difficult to ensure that.
