FDM介绍(国外英文资料) Rapid prototyping technology is a new advanced manufacturing technology developed in the late 1980s, is considered a major breakthrough in the field of manufacturing technology in recent 20 years, has significant and the profound influence on the development of manufacturing industry. Rapid prototyping technology from the inception, with significant technological advantage (the largest reduction of product development time and cost) has maintained the momentum of rapid development, has appeared in a number of mature commercial product, practical products with remarkable achievements. At present, people are not only satisfied with the needs of prototype production, but also the rapid manufacture of personalized and small batch parts. People are eager to make their 3D product models available in the office and even at home, and quickly and directly. Everyone who uses 3D modeling software (not just designers with strong financial backing) is eager to have a rapid manufacturing facility. Its like every people who use the computer using the printer will edit their own text print immediately into the same type. In this context, higher requirements for rapid prototyping equipment have been put forward: first of all, the capability of direct manufacturing of functional parts is not only satisfied with model making. Followed by cost pressures. Private or family financial resources are limited, and the cost of equipment procurement, operation and maintenance costs can be accepted by SMEs and even families. Thirdly, the equipment is easy to use and reliable. Finally, the cleanliness of the equipment, forming process does not cause pollution. These conditions require rapid prototyping equipment to work like a 3D printer. However, the commercialization of high-end RP system equipment is expensive, high operating costs, high environmental requirements, and requires special staff operations and routine maintenance. A three-dimensional printing forming based on injec
