3D printing device for preparing cardiovascular stent and use method

Abstract

The invention discloses a 3D printing device for preparing a cardiovascular stent and a using method, and belongs to the technical field of 3D printing equipment, the 3D printing device comprises a material base, the material base is fixedly mounted on one side of a 3D printer main body, a plurality of storage mechanisms are detachably connected to an inner cavity of the material base, and a vacuumizing mechanism is fixedly mounted at the top of the material base; the vacuumizing mechanism is movably connected with the bottom storage mechanism, and the air curtain mechanism is fixedly installed on one side of the storage mechanism. By means of the designed storage mechanism, vacuum storage of consumables in a wire disc is achieved through vacuumizing treatment on a vacuum cover, the influence of external water vapor on the consumables during storage is reduced, the storage requirement of the self-water-absorption consumables is met, meanwhile, a heating jacket is arranged on the front portion of the mixing mechanism in advance, the pretreatment length of the consumables after discharging is reduced, and the storage efficiency of the consumables is improved. The storage safety of the wire rod after 3D printing is stopped is improved, the wire rod pretreatment adaptive capacity of small-amount multi-frequency printing is met, and the instant storage effect after consumable material treatment is improved.

Description

technical field [0001] The invention relates to the technical field of 3D printing equipment, in particular to a 3D printing device for preparing a cardiovascular stent and a method for using it.

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a 3D printing device for preparing a cardiovascular stent and a method of use to solve the problem that the cardiovascular stent proposed in the above-mentioned background technology is easy to adhere to the surface of the rotating shaft. Stress collapse occurs due to the deflection of the cardiovascular stent, and the cardiovascular stent lacks relative support capacity, which leads to the problem of low yield rate during the printing and processing of the cardiovascular stent
