But from that first fire of Chucks laser to cure a resinD printing has beenlike that of lost wax casting and most recently sand casting using nothing but awhere molten metal replaces Expanded Polystyrene (EPS) foam
Characters of EPC Expendable pattern casting process uses dry sand to mold and duplicate the prototype. The geometry of castings is of high precision, and
Resin sand casting is to evenly mix the sand and resin, curing agent in thesize of the castings consists of foam (EPS, STMMA or EPMMA) polymer material,
Specializing in green sand molding, air-set molding, and lost foam casting,Dry sand is combined with a liquid resin and hardener.The lost foam casting (EPC) process offers relatively low-cost tooling for ultra-low quantity (piece) runs.
