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.
