As a new type of rapid prototyping technology, 3D printing technology effectively solves the problems of large errors and waste of resources in traditional manufacturing technology. Compared with other technologies, DLP technology has the following advantages: high reliability, high brightness, rich and gorgeous colors, and is very suitable for portable devices. This article aims to study the application of embedded microprocessor-based DLP3D printing in automated precision manufacturing. This article puts forward the idea of applying DLP3D technology to more automated precision manufacturing. This article introduces the embedded microprocessor, 3D printing technology, and related algorithms in detail. At the same time, this article also conducts experiments on DLP3D printing technology. Through the analysis of samples printed by DLP3D technology, the experimental results show that the material deviation value of DLP3D printing based on embedded microprocessor is generally small, compared with other technology printing the deviation value of the material is also reduced by 15.6%.

Since the advent of polymeric materials, many structures have always been built for engineering purposes. On the one hand, the emergence of composites containing glass fibers has had a significant impact on reducing the weight of structures in various industries. On the other hand, with the advent of 3D printers, many limitations for the geometry of engineering structures were removed. In this research, due to the wide application of these two sciences, a new type of composite absorbers has been introduced. The presented absorbers have glass fiber-reinforced polymer cores (GFRP) or low-density polyethylene cores (LDPE), the shells of each sample are made of PLA or ABS. In this study, 24 different samples were tested under quasi-static loading. The samples were examined in three different groups. In the first group, no cores were used, but in the second group, GFRP cores were used, and in the third group, LDPE cores were used. Triangular, trapezoidal, semielliptical, and square sections were studied, and the results showed that the lowest maximum force was related to samples with semielliptical cross section, then the maximum force increased by changing the cross section from triangular to trapezoidal and then to a square. In addition, the maximum force was higher in the GFRP core than in the LPDE core.

3D printing, known as the “new industrial revolution,” has set off an upsurge in the scientific and technological field in recent years, and 3D printing of digital light processing technology has even improved the performance and efficiency of 3D printing. This technology uses the projection principle to form; no matter the size of the workpiece, the forming speed is not affected. It uses very cheap lamp radiation, the system has no injection-molded components, there is no nozzle clogging problem of traditional molding systems, and maintenance costs are greatly reduced. In this paper, based on digital light processing 3D printing technology, light-curing reactive functional materials commonly used in digital light processing 3D printing are prepared. In the past, most of these materials were imported. In this paper, by adjusting the DLP technology, a water-soluble photocurable reflection material is constructed, a method for shaping the reaction material. It conducts experiments on the preparation and performance research of water-soluble photocurable reaction materials through formulation and process optimization. It prepared a water-soluble photocurable reactive functional material and compared it with traditional imported materials. Due to the characteristics of UV curing and good mechanical properties and water solubility, it provides a new idea for the preparation of 3D printing-related functional materials.
