This study presents an alternative approach of producing sheet metal forming dies that are suitable for application in a new sheet metal component development phase. It was found that the sheet metal forming dies can be fabricated within one day. The advantages of the proposed method for fabricating sheet metal forming dies include low processing time and low manufacturing cost. This study of 8 vol.% Zirconia filled into the Epoxy-based were mixed by ultrasonic vibration to improve powder agglomeration effects. The result show that the best time to disperse shock for 20 seconds, reducing the maximum particles size consists of 4 μm to 1 μm. However, Zirconia filled Epoxy compared with pure epoxy hardness increased by 57.3 % and compressive strength increased by 52.1 %. The surface roughness was 899 nm, wear of low-volume production decreased by 43.8 % and compared with commercial Aluminum filled Epoxy cost reduction of 72 %.
