The obvious advantage of 3D printing is that it can directly generate parts of any shape from computer graphics data without machining or any molds, which greatly shortens the product development cycle, improves productivity and reduces production costs. At the same time, 3d printing can also print some appearances that cannot be produced by traditional production technology. At the same time, 3d printing technology can also simplify the entire production process, which is fast and effective.
                                                                                                  
1. There is no additional cost for making messy items. As far as traditional production is concerned, the more chaotic the shape of the object, the higher the production cost. For 3D printers, the cost of manufacturing objects with messy shapes is not increased. It takes no more time, technology or cost to make a gorgeous object with messy shapes than to print a simple box. And save material. There is no need to remove scraps, which improves the utilization rate of materials and reduces costs by abandoning the production line.

2. It can achieve high precision and high complexity, and can manufacture very complicated parts that cannot be manufactured by traditional methods. And it can automatically, quickly, directly and accurately convert the three-dimensional design in the computer into a physical model, and even directly manufacture parts or molds, thereby effectively shortening the product development cycle.

3. With a good design concept and design process, three-dimensional printing technology can also simplify the manufacturing process, and produce a single item quickly, efficiently and cheaply. Compared with machine-made parts, the printed product is 60% lighter and equally strong.

4. No assembly required. Three-dimensional printing can integrate parts. Traditional mass production is based on assembly lines, where machines produce identical parts, which are then assembled by robots or workers. The more components a product has, the higher the time and cost required to assemble it. The 3D printer can print the door and supporting hinges at the same time through layered manufacturing without assembly. Eliminating assembly shortens the supply chain and saves manpower and transportation costs. The shorter the supply chain, the less pollution.
