Problems solved by technology
Most of the solutions now are to purchase secondary curing machines on the market for secondary curing. The power is small and cannot meet the needs of rapid secondary curing.
In addition, the curing machine is separated from the additive printing equipment, which not only increases the cost, but also is very inconvenient to use
[0003] Therefore, the defect in the prior art is: in the prior art, the model is subjected to secondary curing, usually using a secondary curing machine for curing, and its power is small, which cannot meet the needs of rapid secondary curing
In addition, the curing machine is separated from the additive printing equipment, which not only increases the cost, but also is very inconvenient to use

The invention provides an additive manufacturing system-based secondary light path secondary curing formation device. The device comprises a digital micromirror device (DLP) projection system, whereinthe DLP projection system comprises a DLP and a control circuit, the control circuit is connected with the DLP and is used for controlling rotation of the DLP to obtain a main light path and a secondary light path, at least one steering optical component is arranged at a light reflection position of the secondary light path, and the steering optical component is used for reflecting light of the secondary light path to a model needed to be reinforced and cured for secondary curing. The device provided by the invention is integrated onto n additive manufacturing system; the steering optical component is arranged in the secondary light path, the model is secondarily cured by light of the secondary light path, no extra molding structure design is needed, no extra ultraviolet light is needed to be bought, and no extra power supply is needed, thus, the cost is greatly reduced, the problem of stray light collection of the secondary light path is solved, and the device is very convenient to use.
Description
technical field [0001] The invention relates to the field of optics, in particular to a secondary curing molding device for a sub-optical path based on an additive manufacturing system. Background technique [0002] In the existing technology, additive manufacturing has subverted the traditional material-removing manufacturing method with its advantages of zero waste, short molding time, and diverse molding shapes, and has innovated the manufacturing theory. It has developed rapidly in recent decades. Among them, the SLA molding machine utilizes the principle of photosensitive resin curing under ultraviolet light to achieve rapid prototyping. Under normal circumstances, the mold formed by the SLA molding machine needs to be cured again under the irradiation of ultraviolet light. Most of the solutions now are to purchase secondary curing machines on the market for secondary curing. The power is small and cannot meet the needs of rapid secondary curing. In addition, the curi...
