介绍了９０年代出现的快速制造零件的“渐增材料制造法”，包括原理、特点及应用．着重介绍了几种比技成熟的具体工艺：立体印刷法、局部激光烧结法、立体底片固化法、三维印刷法、叠层制造法、熔融沉积造型法、循环掩模沉积工艺等． This article introduces the “incremental material manufacturing method” of rapid manufacturing parts appearing in the 1990s, including principles, characteristics and applications. Several specific techniques that are more mature than technology are introduced emphatically: three-dimensional printing method, partial laser sintering method, stereolithography method, three-dimensional printing method, laminated manufacturing method, fused deposition modeling method and cyclic mask deposition process.
