Digging into metal additive manufacturing quickly reveals how expensive it can be, as some parts produced using incumbent technologies, such as laser sintering and binder jetting, can cost thousands of dollars. If there’s one lesson Matt Sand, President of 3DEO, a Los Angeles, California-based metal AM parts supplier, has learned over the last few years, it’s that cost is everything when it comes to serial production.
“If you’re not in the ballpark on cost, you might as well not even play the game because there’s no way to get into production without being cost competitive with conventional manufacturing techniques,” Sand says. “If you are not cost competitive, you’re not at the table,” So, to get the total cost structure down, 3DEO developed an end-to-end manufacturing process around Intelligent Layering, a very low-cost metal additive manufacturing technology the company’s founders invented. Based on binder jetting technology, Intelligent Layering uses a proprietary spray system to bind the entire layer, and then uses a CNC end mill to cut the perimeter of the part and any internal features.
