The authors developed a process for solid mold investment casting using ice patterns. The authors then collaborated with O’Fallon Casting Foundry, O’Fallon- Missouri, to implement the use of ice patterns for the shell mold investment casting process. Various castings of different dimensions and geometry were produced using the shell mold process. These included bolts, coin replicas, paper weights, and dental bars. The bolt castings were made from an M12 bolt pattern and were studied to analyze the quality of the developed investment casting process. The studies demonstrated the accuracy and repeatability of the process. A comparative study was done between the solid mold investment casting and the shell mold investment casting.
