Rapid prototyping technology is a generic term for the rapid production of prototypes or parts based on CAD models. It integrates modern scientific and technological achievements such as CAD technology, numerical control technology, laser technology and material technology, and is an important part of advanced manufacturing technology. It can automatically, directly, quickly, and accurately model the design idea into a functional prototype or a direct-manufactured part based on a CAD model (electronic model), and generates almost arbitrarily complex parts without the use of molds and tools. Rapid docking from design to manufacturing. Therefore, the technology can quickly evaluate and modify the product design, effectively shorten the product development cycle, reduce the development cost, and meet the requirements of the rapid development and rapid manufacturing of new products in today’s highly competitive market. The product's market competitiveness and the company's comprehensive competitiveness.

Laser selective sintering is one of the important process methods in rapid prototyping manufacturing. The technology adopts the principle of layer-by-layer material addition to slice and process the 3D solid model to generate a laser sintering scanning path. Then, the laser beam is scanned along the scanning path by the xy laser scanning instrument, and the assimilation congener powder materials are sintered layer by layer ( Such as plastic powder, nylon powder, wax, ceramics or), mixed powder of metal and binder or metal powder, etc. After sintering and layer stacking, the desired three-dimensional workpiece is finally formed. This manufacturing method has the characteristics of fast molding speed, high precision, good surface quality, simple post-processing, and time-saving. It is a vital technology and creates a new method for the development of manufacturing technology.

The agricultural machinery production process is unique. Many parts have more complex shapes, such as farmland machinery, soil preparation machinery and harvesting machinery. In addition, there are many complex surfaces, such as the surface of the plough body, rotary blade of the rotary cultivator, water pump impeller, feed screw, and the like, and the shape needs to be adjusted accordingly according to specific production conditions. Therefore, the use of traditional mechanical processing methods to develop such agricultural machinery parts, not only the development of a long time, the processing process is complex, and it is difficult to achieve the desired results. The use of advanced laser rapid prototyping integration technology not only greatly shortens the development cycle of new products and reduces development costs, but also the manufacturing quality is superior to traditional manufacturing methods.
