Abstract: A printing method based on consumable management, a printing system, and a printing device are provided. The method is applied to the printing device including an image sensor and/or a near-field sensing component, and includes: receiving a print job; performing first identification on an image label of a consumable container by using the image sensor, to obtain first consumable identity information corresponding to the image label, and/or performing second identification on a near-field sensing tag of the consumable container by using the near-field sensing component, to obtain second consumable identity information corresponding to the near-field sensing tag; performing consumable verification based on the first consumable identity information and/or the second consumable identity information; and performing, by the printing device, the print job in response to a verification result being compatible with the print job.

Abstract: An aluminosilicate molecular sieve catalyst, its preparation and application thereof are provided. The catalyst shows a desorption curve having three peaks P1, P2 and P3 in its NH3-TPD pattern. The desorption temperatures corresponding to the summits of the three peaks P1, P2 and P3 are respectively in a range of 180-220° C., 250-290° C. and 370-410° C. The catalyst shows a higher activity, selectivity and stability when used for producing alkylaromatic hydrocarbons by gas-phase alkylation of aromatics with olefins.

Abstract: The present application provides a printing material uniformity adjustment method and a device. The method is applied to a printing device. The printing device is equipped with a forming module, and the forming module includes a platform assembly. The method includes: driving the platform assembly to stir printing material by moving. The present application achieves automated, efficient, and uniform stirring of the photocurable printing material without requiring an extra stirring component. The platform assembly can serve as a stirrer in addition to serving as a forming platform, reducing product cost, minimizing human intervention, and improving operational convenience.

Abstract: The present application provides a 3D printing method, a forming mechanism, and a printing device.

Abstract: A printing method is provided. The method includes determining whether the receiving cavity is sealed to a predetermined standard, and controlling the forming platform to move away from the light-transmissive assembly and filling the receiving cavity with gas to release the forming platform from the light-transmissive assembly. The method further includes controlling the forming platform to move to a next printing position to perform a light curing process light curing process. A printing device is also provided.

Abstract: Disclosed are an injectable sustained-release pharmaceutical formulation and a process for preparing the same. In some embodiments, the formulation comprises an active ingredient in a therapeutically effective amount, an amphipathic molecule, an organic acid and/or a salt thereof which is hardly soluble in water, and an oily solvent. The injectable sustained-release pharmaceutical formulation provides a good sustained-release effect for various active ingredients, in particular peptides, proteins, nucleic acids and saccharides.
