ABSTRACT In this study, Polymer (Primecast® 101-EOS)patterns were produced with the EOS Formiga P110 system, and these patterns were compared with conventional wax patterns using their suitability for the investment casting (IC) method. Besides, Scanning Electron Microscope (SEM) and Thermal Analysis (DSC and TGA) were applied produced to investigate the properties of Primecast® patterns and their suitability for the IC. A356 aluminium alloy castings were produced in a Vacuum-Assisted Casting (VAC) machine, and graded precision casting method using conventional wax and Primecast® patterns and surface roughness and dimensional accuracy measurements were carried out on the patterns and cast parts. In light of the data obtained from the study, Primecast® powder is thought to have several advantages for the ceramic shell IC method.

用于熔模铸造 (IC) 的选择性激光烧结 (SLS) 方法生产的聚合物图案的表面质量和尺寸精度的研究

摘要 在本研究中，聚合物 (Primecast® 101-EOS) 模型是使用 EOS Formiga P110 系统生产的，并使用它们对熔模铸造 (IC) 方法的适用性将这些模型与传统蜡模型进行了比较。此外，还使用扫描电子显微镜 (SEM) 和热分析 (DSC 和 TGA) 来研究 Primecast® 图案的特性及其对 IC 的适用性。A356 铝合金铸件在真空辅助铸造 (VAC) 机器中生产，并使用传统蜡和 Primecast® 模型进行分级精密铸造方法，并对模型和铸件进行表面粗糙度和尺寸精度测量。根据研究中获得的数据，Primecast® 粉末被认为具有陶瓷壳 IC 方法的几个优势。
