近年来,美国继续保持其在快速原型制造(RP)技术领域内的领先地位。由于政府、各大公司(如Genemotor、IBM等)以及军事部门的大力支持,提供了大笔资金,使得许多高校的RP实验室吸引了大批人才,装备更加齐全。特别是材料与工艺科学研究水平的大幅度提高,一方面使得许多原有工艺更为 In recent years, the United States has continued to maintain its leading position in the field of rapid prototyping (RP) technology. Thanks to the strong support from the government, major corporations (such as Genemotor, IBM, etc.) and the military department, a large sum of money has been provided to make RP laboratories in many universities attract a large number of talents with more complete equipment. In particular, material and technological research greatly improve the level of science, on the one hand makes many of the original process more
