Three-dimensional printing, also known as additive manufacturing, is an emerging rapid manufacturing technology with an ever-expanding range of applications. From the automotive and aerospace industries to lighting fixtures and accessories, 3D printers are increasingly becoming a part of our daily lives. So, what types of models can be produced using 3D printers?
　　1. Industrial prototypes.
　　In traditional industrial design, prototypes are typically manufactured using CNC machining. However, when a model’s complexity reaches a certain threshold, CNC machining becomes not only time-consuming but also results in a significant drop in precision. 3D printing technology works exactly the opposite way: the more complex the model, the faster it prints and the more cost-effective it becomes. As a result, it forms a highly complementary relationship with CNC machining, and 3D-printed models have become a vital solution in this field.
　　Model Toys and Ornaments.
　　For many individual 3D printing enthusiasts, creating 3D-printed model toys and ornaments is undoubtedly a great source of enjoyment. On one hand, it allows them to turn their imaginative ideas into exquisite physical models; on the other hand, it enables users to customize their favorite model toys at a lower cost. In particular, since the introduction of SLA 3D printers, 3D printing technology has also found its way into applications that demand high model precision, such as animation and handicrafts.

 
　　3. Creative Lighting Fixtures.
　　Compared to traditional manufacturing techniques such as CNC machining, 3D printing technology offers unique advantages in the production of creative lighting fixtures. Since 3D printers can directly print lighting designers’ creative concepts into three-dimensional physical models, the more complex the design, the more pronounced the time and cost savings become. According to industry statistics, 3D printing technology can help lighting manufacturers save at least 30% in time costs and 40% in production costs. Consequently, 3D-printed models of this type are also quite common.
　　4. Illuminated Advertising Letters.
　　The production of illuminated advertising letters is a typical example of small-batch, personalized customization, with the manufacturing of letter casings being a critical step. Traditionally, the fabrication of advertising letter casings required technicians to perform a series of labor-intensive processes—including cutting, bending, slotting, welding, and polishing—to complete the manufacturing of illuminated letter casings, which was both time-consuming and costly. Consequently, in recent years, 3D-printed letter casing models have become increasingly popular, and specialized 3D printers for advertising illuminated letters have emerged, significantly boosting production capacity in this sector.
