Molds or cores are made by spreading a blended silica sand and dry acid binder mixture on a flat surface. The bed of blended sand is swiped with a leveling bar as the print head passes and deposits a chemical activator to create the printed shape.Molds or cores are made by spreading a blended silica sand and dry acid binder mixture on a flat surface. The bed of blended sand is swiped with a leveling bar as the print head passes and deposits a chemical activator to create the printed shape.moulds and cores in refractory materials such as silica sand. The main properties of silica sand that are essentially related to the traditional moulding and core-making processes are size , and refractoriness. The silica sand used for 3DP must be appropriately selected also for the layerbased manufacturing process involved in 3DP.
