Description
Technical field
This utility model relates to biometric print machine technology field, particularly to a kind of biometric print machine motion platform and biometric print machine.
Background technology
Biological 3D prints and refers to by the 3D principle printed and method, and biomaterial (including natural biologic material and synthesising biological material or cell solution) prints the technology of the three-dimensional structure becoming design.Compared with common 3D printing technique, biological 3D printing technique be characterized in that its biological tissue produced or organ also have certain biological function, the further growth being required to be cell and tissue provides condition, and, owing to building the cell of biological tissue, on microcosmic, the complex biological function of the transmission of intercellular signal and tissue only could be realized according to biological regularity exact placement, therefore, the process that biological 3D prints is except to allow except cell survival, in addition it is also necessary to constantly pursue realizing cell and more arrange accurately.Visible, biological 3D printing technique is faced with many particular technology problems being different from common 3D printing technique in development.
Biological 3D printing device adopts the biological prepared Chinese ink ejection that shower nozzle will be made up of active somatic cell, and biological prepared Chinese ink is arranged in preset structure along with the movement of shower nozzle on print carrier, ultimately forms biological tissue.At present, how to improve the printing precision of biometric print machine further, make cell arrangement more accurate, and how to improve the printing effect of biometric print machine, ensure that in print procedure, cell has higher survival rate and better physiological function, become the key technical problem that the biological 3D printing technique of restriction develops further.

Due to relative to general industry equipment such as the lathes being used for processing relatively large level product marble and the timber etc. of m (the such as magnitude be), the processing capacity of 3D printing device is minimum, stroke is short, driving force demand is also very low, therefore, existing 3D printing device is all only with the monolateral type of drive of Y-axis.And biometric print machine has less machining unit and shorter stroke relative to common 3D printing device, the blood vessel that such as biometric print machine prints only has cm magnitude, therefore, generally believe in the industry, biometric print machine motion platform also only need to adopt the monolateral type of drive of Y-axis, so, existing biometric print machine motion platform only includes a Y-axis driving mechanism.
But, inventor finds through research, and the biometric print machine motion platform of the monolateral driving of this Y-axis causes the printing precision of existing biometric print machine and the major reason that printing effect is relatively low actually just, and existing concrete analysis is as follows:
(1) the biometric print machine motion platform of the monolateral driving of existing Y-axis, it is difficult to meet the high-precision printing demand precisely being moved by shower nozzle and positioning.Due in biometric print field, three-dimensional structure scale of construction level is little, especially when shower nozzle is in time spraying biological prepared Chinese ink in the way of point-like injection, the cell to printing is needed to arrange more accurately, the positioning precision of biometric print machine motion platform is just proposed very high requirement by this, minimum error is likely to cause the defective of printed product, and the biometric print machine motion platform of the existing monolateral type of drive of employing Y-axis, its master end and slave end easily produce error, affect kinematic accuracy, thus being unable to reach the high-magnitude printing precision requirement of biological 3D printing device.Especially when Y-axis stroke is longer, this impact becomes apparent from, inventor finds through test of many times, when Y-axis haul distance is 300mm, the biometric print machine motion platform of the monolateral type of drive of Y-axis, slave end and master end error in Y-axis can reach 0.05mm, although this error is in general industry field, even common 3D prints field and broadly falls into only small error, but this error is for the cell of in biological 3D printing field tens to hundreds of micron, can have a strong impact on the exact placement of cell.
(2) and even more important, the biometric print machine motion platform of the monolateral driving of existing Y-axis, which limit the further raising of biometric print machine printing effect.Owing to biological 3D prints raw-material characteristic, in biological prepared Chinese ink, the activity of cell and survival rate can reduce with the increase of time-write interval, this just movement velocity and printing effect for biometric print machine motion platform propose very harsh requirement, and existing biometric print machine motion platform, moment needed for its motion and work provides by unilateral driving mechanism, under the premise of certain required precision, the mode of the monolateral driving of Y-axis cannot provide higher output power, and it is limited to the rigidity that biometric print machine is overall, existing biometric print machine motion platform acceleration in the Y-axis direction is also restrained.Visible, the biometric print machine motion platform of the monolateral driving of existing Y-axis is difficult to meet the requirement of the biological 3D print speed printed and printing effect.
