Embodiment Construction

[0015] The invention discloses a new light-curing rapid prototyping system based on digital micromirror technology. The system consists of two parts: a processing and forming system and a digital micromirror device projection device. figure 1 And example the present invention is described in further detail.

[0016] like figure 1 As shown, the first part is a processing and forming system, including a protective cover 1 , a slider 2 , a guide rod 3 , a transparent material tray 6 , a stepping motor 7 and a forming table 10 .

[0017] The transparent material tray 6 is used to hold the liquid photosensitive resin 5, the guide rod 3 is located next to the transparent material tray 6, the slider 2 is installed on the guide rod 3, the forming table 10 is installed on the slider 3, and is located above the transparent material tray 6, The guide rod 3 and the stepping motor 7, the slide block 2, the guide rod 3, the transparent material disc 6 and the forming table 10 are all locat...

Abstract

The invention discloses a photocuring rapid prototyping system, the structure thereof is that: a transparent materials tray used for loading liquid photosensitive resin is arranged in a safety cover, a guide rod is arranged beside the transparent materials tray, a sliding block is arranged on the guide rod, a prototyping platform is arranged on the sliding block and above the transparent materials tray, the guide rod is connected with a stepper motor; a digital micro-mirror device is arranged below the transparent materials tray and in the emitting light path of an ultraviolet mercury lamps, and a snoot is covered on the digital micro-mirror device. By the invention, the prototyping efficiency and precision of products are increased and the hardware requirement and the running cost of the photocuring rapid prototyping system are reduced. The invention provides a novel rapid prototyping method for developing a new product with low cost, and has the advantages of low acquisition cost and running cost, thus being applicable to small and medium enterprises.

Description

technical field [0001] The invention belongs to the field of rapid manufacturing, in particular to a novel photocuring rapid prototyping system based on digital micromirror technology Background technique [0002] Stereolithography Apparatus (SLA) is one of the most researched, most mature and widely used rapid prototyping methods in the world. It uses the principle that the chemical and thermal effects of light energy can change the liquid resin material, selectively solidifies the liquid resin, and can produce the required three-dimensional solid model without contacting the liquid resin material. The traditional SLA method usually uses a galvanometer scanning system to scan the laser beam point by point onto the resin surface to expose and cure it. This forming system has the following disadvantages: (1) the laser light source is used, which has high cost and short life; (2) the use of The galvanometer-type point scanning method has slow scanning speed and low forming ac...
