Additive manufacturing opens unique design freedoms. Fillets and radii are always pos- sible, machining a relief area can be incor- porated easily, no draft requirements leads to lower weight, and cores can be eliminated where used due to back draft.—Shah


Isolated hot spots can be fed with spot risers. —Shah


Bottom gating is possible for uniform filling with the least turbulence.—Shah


Designers don’t have to account for core split lines, flash or veins. There is flexibility with the placement of feeding aids such as chills, risers, filters, gates, in-gates, and zircon facing cores.—Shah

A functional machined casting for a rear housing in a dual clutch transmission was produced in three weeks using 3-D printed sand technology. This enabled the customer to evaluate several designs quickly and achieve short time-to-market.
