Abstract

The invention discloses a rapid and continuous ultraviolet light curing stereoscopic prototyping system and method. The rapid and continuous ultraviolet light curing stereoscopic prototyping system comprises upper computer control software, an embedded controller module, an ultraviolet optical engine module, a prototyping lifting platform module, a position detection module, a resin container module and a focusing assisting module. During rapid prototyping, an ultraviolet optical engine and a stepper motor are controlled to work synchronously through mutual cooperation of the upper computer control software and the embedded controller module, pictures are projected to the bottom of a prototyping platform by the ultraviolet optical engine through an oxygen semi-permeable membrane at the bottom of a resin pool, the stepper motor drives the prototyping platform to move upwards continuously according to slicing parameters, thus, the time required for curing of each layer of a model is shortened, and the curing prototyping speed is increased.

Description

technical field [0001] The invention relates to the field of rapid prototyping, in particular to a rapid continuous ultraviolet light curing three-dimensional molding system and method. Background technique [0002] Rapid prototyping (RP) technology is an advanced manufacturing technology developed in the 1990s. It is a key common technology for the development of new products for manufacturing companies. Product competitiveness has a positive role in promoting. Since the launch of the first commercial rapid prototyping machine by 3D Systems in the United States in 1986, there have been more than a dozen different molding methods, among which the more mature ones are fused deposition modeling (FDM), powder sintering molding (SLS) and light curing molding (SLA). ) and other methods, while rapid prototyping technology has been widely used in the manufacturing industry in developed countries, and a new technical field has emerged. Among the many existing rapid prototyping met...
