3D Printer Patterns Evaluation for Direct Investment Casting

摘要

The term direct investment casting represents the employment of pattern fabricated by rapid prototyping technique have been reduce the cost and production lead time. The non-wax materials having robust ability on producing pattern in accuracy stability and clean burnout. However 3D printer(3DP) parts are powder based materials and not easily burnout during firing process. The purpose of this investigation were to evaluate the ZP150 powder materials as a sacrificial pattern to be used in investment casting(IC) process. Result shows powder based patterns of 3DP process failed to disintegrate completely even at high temperature during collapsibility investigations. However the pattern become brittle and easily remove by water pressure. Therefore the ceramic mould can be used for metal casting.
