快速成型（RP）技术提供了从各种模型材料制造初始原型的能力。Stratasys熔融沉积建模（FDM）是一种典型的RP工艺，可以制造出ABS塑料的原型。为了预测FDM零件的力学行为，了解原始FDM工艺材料的材料性能以及FDM构建参数对材料各向异性性能的影响至关重要。本文对用FDM 1650加工的ABS零件的性能进行了研究。采用实验设计（Design of Experiment， DOE）的方法，研究了FDM的工艺参数，如光栅方向、气隙、磁珠宽度、颜色和模型温度。测量了定向制造样品的抗拉强度和抗压强度，并将其与注塑成型FDM ABS P400材料进行了比较。对于道路之间重叠0.003英寸的FDM零件，典型的抗拉强度范围为注塑成型ABS P400强度的65%至72%。抗压强度范围为FDM ABS注塑成型的80% ~ 90%，并根据试验结果制定了FDM零件设计的若干构建规则。
Rapid Prototyping (RP) technologies provide the ability to fabricate initial prototypes from various model materials. Stratasys Fused Deposition Modeling (FDM) is a typical RP process that can fabricate prototypes out of ABS plastic. To predict the mechanical behavior of FDM parts, it is critical to understand the material properties of the raw FDM process material, and the effect that FDM build parameters have on anisotropic material properties. This paper characterizes the properties of ABS parts fabricated by the FDM 1650. Using a Design of Experiment (DOE) approach, the process parameters of FDM, such as raster orientation, air gap, bead width, color, and model temperature were examined. Tensile strengths and compressive strengths of directionally fabricated specimens were measured and compared with injection molded FDM ABS P400 material, For the FDM parts made with a 0.003 inch overlap between roads, the typical tensile strength ranged between 65 and 72 percent of the strength of injection molded ABS P400. The compressive strength ranged from 80 to 90 percent of the injection molded FDM ABS. Several build rules for designing FDM parts were formulated based on experimental results.
