It’s nearing 40 years since 3D printing was conceived in 1981, but widespread additive manufacturing is now close at hand. But scale will arrive in the next few years. Yes, the part/bed sizes of 3D printers and speed-to-volume still have room to grow. It is this final achievement in metal that will drive a systemic global impact. Plastics, composites, and now metals give designers a wide range of choices and capabilities in each basic material type. Last month ( MD July 18), this column cited industry data indicating that rapid prototyping technologies are on the cusp of achieving widespread additive manufacturing capabilities: 875% growth in five years, 30 new equipment manufacturers in the past two years, and companies with more than 100,000 3D-printed units already in the marketplace. The 6th Manufacturing Process: 3D Printing has arrived. If the choice of manufacturing process type was complicated before, that complexity is about to get multiplied. Is sales forecasting high volumes? Do we need a continuous production line(s), or will we make the product in discrete lots or batches? All the decades of “familiar decisions” that answered such questions quickly are about to get shaken up. There are economic considerations that precede design engineering. Great design engineers understand the nuances of these processes and tailor their designs accordingly. For decades there have been five basic types of manufacturing processes.
