Rapid Prototyping (RP) technology breaks through the traditional processing mode and is a major breakthrough in the manufacturing technology field in the past 20 years. Rapid prototyping technology combined with technologies such as scientific computing visualization and virtual reality provides a new measurable and touchable approach between designers, manufacturers and users.
Rapid prototyping technology can automatically, quickly, directly and accurately transform design ideas into functional prototypes or directly manufacture parts (mold), effectively shortening the product development cycle, and is a powerful tool to improve product quality and reduce product cost. . At its core is a new forming technology based on digital. Rapid prototyping technology has a profound impact on the manufacturing model, prototype and formwork manufacturing.
RP systems can be divided into two broad categories.
(1) Forming techniques based on laser or other light sources, such as Stereo Lithography (SL), Laminated Object Manufacturing (LOM), Selected Laser Sintering (SLS), shape deposition manufacturing (Shape Deposition Manufacturing, SDM), etc.;
(2) Injection-based forming techniques such as Fused Deposition Modeling (FDM), Three Dimensional Printing (3DP), and the like. RP is characterized by high technology integration and high production flexibility.
