Concept of Prototype Rapid Prototyping Technology
Many people do not understand what rapid prototyping technology is. Below is a detailed introduction to prototype rapid prototyping technology: Rapid prototyping technology, also known as rapid prototyping manufacturing technology. Abbreviated as RPM. It has a history of over thirty years. The principle of rapid prototyping is a new technology that uses material stacking to form prototypes. Prototype rapid prototyping technology encompasses a wide range of disciplines, including mechanics, numerical control, CAD, 3D graphics, layered manufacturing technology, laser, and material technology. Prototype rapid prototyping is achieved by irradiating a material with a laser, which melts and accumulates layer by layer to form a solid model. Prototype rapid prototyping can use three-dimensional CAD graphics to directly convert the model into a part, with fast molding speed and low cost,
What are the processing methods and characteristics of prototype rapid prototyping technology?
There are two main processing methods for prototype rapid prototyping technology: first, photopolymerization rapid prototyping processing method. The material used for photopolymerization is powdery, and most plastics, nylon materials, transparent PC and PCMM materials can be used as photopolymerization materials. The advantage of photopolymerization materials is that they are suitable for many materials, providing customers with a wide range of materials to choose from. photopolymerization rapid prototyping method can process some large products, products with low precision requirements, etc. 2、 Laser selective sintering rapid prototyping processing method. The material used in laser rapid prototyping technology is photosensitive resin. The prototype of laser rapid prototyping is a prototype with good process requirements, accurate precision, and smooth surface.
The six major advantages of rapid prototyping of prototypes:
1、 The emergence of rapid prototyping of hand boards is relatively early, and after the precipitation of time, the maturity of the process is high.
2、 Rapid prototyping can directly obtain a complete solid model from CAD model drawings through a rapid prototyping system, and its molding speed is quite fast.
3、 Rapid prototyping technology can process any complex prototype model, which CNC cannot process or requires three-dimensional structure models. Rapid prototyping can achieve both, forming in one go without the need for secondary processing.
4、 Rapid prototyping technology can be networked and implemented in automated production through other computing technologies.
5、 CAD three-dimensional graphics visualize models, improve the accuracy of model production, and reduce the occurrence of errors.
6、 After obtaining the prototype through rapid prototyping, it can be directly compared with the original mold shape to promptly correct errors.
The main features of rapid prototyping technology for prototypes are:
Rapid prototyping can create models of any three-dimensional shape. Not affected by structural complexity, it can be formed in one go without the need for processing the parts. Rapid prototyping can even produce a prototype in half a working day, with high efficiency. Rapid prototyping technology occupies an important position in manufacturing technology, reflecting the intelligence and automation of modern technology.
