Problems solved by technology

[0005] At present, the motor-assisted micro-injector type extrusion deposition manufacturing (MAM) device generally adopts an integrated structure for machining, that is, the bracket supporting the driving device, the back plate and the lower bracket are processed in an integrated manner. The cost is high, because a large amount of processing materials will be wasted in the processing process, and high processing accuracy requirements are required, thus limiting the production range of printer manufacturing

Embodiment 2

[0041] The technical solution of this embodiment is basically the same as that of embodiment 1, except that: figure 2 with Figure 7 As shown, two first screws 413 are installed on each connecting plate 411. When adjusting the coaxiality of the piston 13 and the barrel 14, it is necessary to loosen the corresponding two first screws 413 on each connecting plate 411. In this embodiment, since the two coaxiality adjustment components 40 are separated from each other, the two connecting plates 411 can be adjusted separately, which prevents interference with the other connecting plate 411 when adjusting one connecting plate 411 Happening.

Abstract

The invention relates to a 3D printer assembly. The 3D printer assembly comprises a back plate, at least one printing component and a coaxiality adjusting component corresponding to the printing component one by one, wherein the printing component comprises a driving device, a piston and a charging barrel; the driving device is mounted on the back plate to drive the piston to move along the axialdirection of the charging barrel; the charging barrel is arranged on the coaxiality adjusting component; and the coaxiality adjusting component is used for adjusting the position of the charging barrel at least transversely or longitudinally in the horizontal direction. According to the 3D printer assembly provided by the invention, the precision requirement during manufacturing is reduced, and when a certain part needs to be replaced, only the part to be replaced needs to be replaced, and the whole assembly device does not need to be replaced, so that the maintenance cost and the cost price are reduced.

Description

Technical field [0001] The invention relates to the field of 3D printing, in particular to a 3D printer component. Background technique [0002] At present, 3D printing technologies commonly used in biological manufacturing mainly include fused deposition manufacturing (FDM), selective laser sintering (SLS), inkjet printing, laser direct writing, extrusion deposition, droplet jetting and other forming technologies. [0003] Extrusion deposition manufacturing technology is a forming method based on continuous direct writing technology. Its working principle is to use compressed air or thrust generated by a motor to extrude the printing material from the barrel, and deposit it in a continuous filament manner through a nozzle. On the substrate, the three-dimensional structure is finally formed by stacking layer by layer. According to the different pressure generation methods, extrusion deposition manufacturing technology can be divided into gas pressure assisted microsyringe extrusio...
