Embodiment 1

[0030] See Figure 1-Figure 7 , the embodiment of the present invention provides a 3D printer for pharmaceutical preparations, including a printer body, the printer body includes a print nozzle assembly 1, a powder supply and powder spreading mechanism 2, a printing platform 28, and also includes a printer for driving the print nozzle assembly 1 The first driving device for mobile printing, the second driving device for driving the powder supply and powder spreading mechanism 2 to move the powder spreading; the first driving device and the second driving device share a group of tracks; the track passes through The supporting structure 35 is erected above the printing platform 28; the first driving device drives the print nozzle assembly 1 to move on the track; the second driving device drives the powder supply and powder spreading mechanism 2 move on the track.

[0031]It should be noted that, in this embodiment, the above-mentioned first drive device and the above-mentioned ...

Embodiment 2

[0060] The difference between this embodiment and Embodiment 1 is that at least one partition is arranged inside the powder supply tank 12 to divide the powder supply tank 12 into different powder supply areas, preferably two. All the other are identical with embodiment 1.

[0061] During use, according to the number of printed tablets, the drug powder can be selectively added to one or several areas of the powder supply tank 12 to realize partial printing. The printing method is the same as the embodiment.

Abstract

The invention provides a pharmaceutic preparation 3D printer which comprises a printer body. The printer body comprises a printing nozzle assembly, a powder supplying and spreading mechanism and a printing platform, and further comprises a first driving device used for driving the printing nozzle assembly to move for printing and a second driving device used for driving the powder supplying and spreading mechanism to move for spreading powder. The first driving device and the second driving device share one group of rails. The rails are erected above the printing platform through a supporting structure. The first driving device drives the printing nozzle assembly to move on the rails. The second driving device drives the powder supplying and spreading mechanism to move on the rails. By the adoption of the pharmaceutical preparation 3D printer, in the powder supplying and spreading process, the printing nozzle assembly does not work; and when the printing nozzle assembly works, the powder supplying and spreading mechanism does not move, i.e., powder spreading and printing mechanisms move respectively in the one-time printing process, so that the possibility that a printing nozzle is contaminated in the powder spreading process is reduced, the service life of the nozzle is prolonged, and the medicine printing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of 3D printing of medicines, in particular to a 3D printer for pharmaceutical preparations. Background technique [0002] 3D printing technology is also called additive manufacturing technology, which is to stack materials point by point to layer by layer stack way to manufacture the product. Compared with traditional subtractive manufacturing, it has the characteristics of short production cycle, less production process and digital production. From the perspective of low-carbon manufacturing, in 3D manufacturing technology, as much material as the product needs can be printed directly, with high resource utilization rate, energy saving and environmental protection. Therefore, it has a good application prospect and is currently a research hotspot in the world. [0003] The printing nozzle and the powder supply and spreading mechanism of the existing pharmaceutical preparation 3D printer are set on the sam...
