Problems solved by technology

However, at present, there is no relevant 3D printing pharmaceutical software, let alone software that can directly print tablets according to the dose by setting parameters
The operator is required to set the thickness of the drug powder layer and the number of printing layers, and can only control the shape of the tablet, which cannot give full play to the advantages of 3D printing in personalized and precise medicine in pharmaceuticals

Abstract

The invention discloses a method for preparing a tablet with any dose based on 3D (three-dimensional) printing. A 3D printing technology is combined with preparation of medicinal tablets, three-dimensional modeling is started on a computer for controlling the printing process of a 3D printer, the medicine dose required by a patient is input after the density of a medicine preparation and the ratio of the radius to the height of the tablet are set, a 3D model can develop the appearance of the tablet which is to be printed, and the tablet with precise dose can be printed after pharmaceutical personnel confirm. The medicine with precision dose, which is required to be taken by the patient and is determined by a doctor according to the individual difference of the patients, the stage of the disease according to the disease degree as well as related physiological index can be prepared into tablets by the 3D printer, so the medicine safety is greatly improved, and customized design and personalized treatment are realized.

Description

technical field [0001] The invention relates to the field of computer-aided drug design using 3D printing, and more specifically relates to a method for preparing tablets of any dosage based on 3D printing. Background technique [0002] As a manufacturing technology, 3D printing has developed rapidly in many fields of science and technology. Due to its advantages such as simple operation, good flexibility, high repeatability, and wide adaptability, it has attracted the attention of drug formulation developers. In-depth research and wide application in high-end pharmaceutical preparations such as release preparations, implants and compound preparations. Since the process can be designed and controlled by computer, the production batch and production scale have less influence on the final product, making it more personalized. [0003] In recent years, 3D printing technology has been increasingly used in the field of pharmacy to prepare special solid dosage forms containing ac...
