Description
Technical Field
The invention relates to the technical field of 3D printing, in particular to a large-format digital projection type photo-curing 3D printer.
Background
The photocuring molding process which is used for realizing commercialized application in a 3D printing system at the earliest time has the characteristics of high molding precision and high molding speed, and has wider application potential along with the continuous abundance of composite photosensitive resins such as ABS, heat-resistant resin, ceramic resin and the like in recent years. The digital light projection forming (digital light processing, digital light) can complete the forming of the cross section outline of a part by one-time projection, has the advantages of high forming speed, high precision, high surface smoothness and the like, and is widely applied to industries such as precision casting, aerospace, biomedical treatment and the like. The constrained digital light projection molding is an important research and development direction because of the characteristics of high material utilization rate, small deformation of a workpiece, simple equipment structure and the like.
The main problems existing at present in the constraint digital light projection molding are as follows: (1) Limited by the projection size of the digital light projector, it is difficult to complete large area print jobs; (2) Excessive peel force when the cured layer is separated from the constraining substrate can cause printing defects and failure of the printing process, thereby reducing printing efficiency and process reliability, and the problem of peeling of the cured layer is further exacerbated by large-area printing. Aiming at the problem of limited printing area, researchers propose to adopt a plurality of digital light projectors to project simultaneously, control the mask images projected by the digital light projectors on the surface of liquid resin to be spliced seamlessly, improve the printing area, but the number of the projectors is increased along with the increase of the printing area, so that the printing cost is too high, and engineering application is difficult to realize; researchers have also proposed using a single projector to achieve large area printing by controlling the relative movement between the resin bath, projector, print pallet. However, in the constraint digital photo-molding, the peeling force of the cured layer from the substrate increases sharply with the printing area, and the current large-area digital photo-printer does not mention the process reliability problem caused by the peeling force of the cured layer. In addition, in the scheme using a single projector, the problem of printing accuracy caused by the problem of motion synchronization and the problem of parallelism of the projector and the resin tank also need to be solved.
Accordingly, there is a need to improve one or more problems in the related art as described above.
It is noted that this section is intended to provide a background or context for the embodiments of the invention that are recited in the claims. The description herein is not admitted to be prior art by inclusion in this section.
