缩短生产原型的时间是加快新产品开发的关键。今天的商用快速成型系统使用不同的技术，使用纸张，聚合物和蜡。快速成型领域（例如汽车行业）的一个重要目标是生产用于功能应用和测试的金属原型。生产金属零件的一种可能性是两步工艺（例如使用熔融沉积成型（FDM）工艺生产蜡原型，然后进行熔模铸造）。FDM系统自1993年3月起安装在弗劳恩霍夫应用材料研究所（IFAM）。另一种可能性是直接制造金属部件（例如不锈钢）。一种新的快速成型工艺，我们命名为“多相喷射凝固”（MJS）用于这项任务。这两种技术的经验和结果。
Reducing the time to produce prototypes is a key to speeding up the development of new products. Today's commercially available rapid prototyping systems work with different techniques using paper, polymers and waxes. One big goal in the field of rapid prototyping (e.g. in the automotive industry) is the production of metallic prototypes for functional applications and testing.One possibility to produce metal parts is a two-step process (production of wax prototypes, e.g. with the fused deposition modeling (FDM) process and subsequently investment casting). The FDM system is installed since March 93 at the Fraunhofer-Institute for Applied Materials Research (IFAM). Another possibility is the direct manufacturing of metallic components (e.g. stainless steel). A new rapid prototyping process which we name ''multiphase jet solidification'' (MJS) is used for this task. Experiences and results with these two techniques are presented.
