Abstract

The invention discloses a multi-material surface exposure bioprinting device and a control method. The device includes a base frame, a mounting plate, a forming cylinder, a nested cylinder with multiple unit cylinders, a first forming platform, a second forming platform, and a forming platform. Control assembly, rotating platform, impurity removal unit, primary curing unit, secondary curing unit and rotary drive motor. The invention adopts the combination of the rotatable forming cylinder and the nested cylinder, so that the printing equipment has the function of multi-material rapid prototyping and the capability of single-material large-size parts forming.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing, in particular to a multi-material surface exposure bioprinting device and a control method. Background technique [0002] Additive manufacturing, also known as 3D printing and rapid prototyping, is a molding method that combines computer-aided design, material processing and molding technology. This technology is different from traditional subtractive or equal-material manufacturing through layer-by-layer processing, and can freely manufacture products of various specific shapes with less material loss. Additive manufacturing, as the fastest-growing new molding method in the past two decades, has gradually expanded its application in biomedicine by virtue of its advantages of personalized customization. [0003] However, a bioscaffold that can be applied is usually composed of regions that perform different functions, and these functional regions are formed of different materials ...
