Abstract

The invention discloses a DLP principle based 3D printer. The 3D printer includes: a resin tank, the bottom plate of which is light-transmitting; a vertical lifting mechanism, which is in fixed connection with a forming platform and is used for adjusting the distance between the resin tank and the forming platform; a computer, which is used for processing a three-dimensional model and segmenting the three-dimensional model into several profile graphs with certain thickness sequentially, and is connected to an electrical control device for controlling automatic lifting of the forming platform by the vertical lifting mechanism and controlling irradiation of a DLP projector on the liquid level of light-cured resin in the resin tank; and the DLP projector, which is arranged below the resin tank and is connected to the computer, and makes the graph light path of the profile graphs transmit the bottom plate of the resin tank so as to irradiate the light-cured liquid resin. According to the invention, the DLP projection technology is adopted and the light cured material forming technology is combined to form a set for system. The system has the characteristics of simple components and compact whole structure, the formed products have improved precision, the manufacturing cost is low, and the product forming speed is faster.

Description

Technical field [0001] The invention relates to the technical field of 3D rapid prototyping, in particular to a 3D printer based on the principle of DLP. Background technique [0002] 3D printing technology is a kind of rapid prototyping technology (RP). It is actually a collective term for a series of rapid prototyping technologies. Its basic principle is laminated manufacturing. The rapid prototyping machine scans the profile of the workpiece in the XY plane. Shape, and intermittently displace the thickness of the layer in the Z coordinate, and finally form a three-dimensional part. [0003] The two corresponding technologies are cutting and casting, but compared with these two technologies, 3D printing technology has its own advantages, that is, it does not waste materials like cutting, and does not require the production of molds like casting. With only one drawing, it can quickly produce models or prototypes, which is widely used in the field of industrial design. And becaus...
