At the AFS Additive Manufacturing for Metalcast-
ing Conference in October 2016, several of these experts dispense advice on what they have learned in designing cast components for this evolving technology. Here, Global Cast- ing Magazine shares 19 of those lessons.
Start Up Front
1 2
Perform your design and casting simulations up front, even though it adds time. Simulate the casting process as soon as possible, make it a priority and get as close to perfect as you can, given the time limitations of the cus- tomer.—David Weiss, Eck Industries
T e design phase is the most critical aspect of a component’s life. Many manufacturing and performance issues created at this stage have a long term impact on product cost. An integrated approach using computer based technology not only reduces lead time, it also improves the design. Technologies that assist creating samples quickly
will help maximize the evaluation time and decisions made during this critical phase.—Tom Prucha, MetalMorphisis

This complex prototype crankcase produced via 3-D printed sand cut 10 weeks from the program and avoided $60,000 in pattern and fi xture cots. Printed core surfaces do not require any draft, so the part weight and wall thicknesses were maintained exactly as designed.
