the advancement of polymers made many previously machined components unnecessary. “So it’s certain that additive manufacturing will negate the need for some machining operations and—in the cases of some prototypes and patterns—it already has,” Sivitter said. “It’s also worth noting that production speed and build window will always be a restriction for 3D printing. However, new machines such as the DMG Mori La- sertec 65—which can deploy metal powder, weld with a laser, and mill in fi ve axes— can improve production and costly reworking procedures.” Developments on
GibbsCAM include the integration of 3D printing as another machine and process that manufactur- ing companies will need to consider and support in the future for integration into their processes, Gibbs said. “In my opinion, the future of manufacturing is Digital Fabrication. This is not my term, I fi rst heard it used by Avi Reichental, CEO of 3D Systems,” Gibbs said. “He uses it to describe the growing integration of func- tionality from part design through multiple integrated manufacturing steps all the way to a fi nished part. The separate component pieces exist today, but not in a single, coordinated solution. “The dream is smart, integrated software that
perfect programs before they get to the machine, eliminating human error from endless edits. “Many CAD/CAM software systems can do some pieces of this. But the fully integrated Digital Fabrica- tion environment promises so much more than a

hodgepodge of patched together software,” Gibbs stated. “Working towards this goal has to be the most important trend in CAD/CAM today. It is a mighty undertaking. But you can see major companies ac- quiring the technologies they need to pursue it.”

allows engineers to design with full consideration of optimal, integrated manufacturing,” Gibbs said, “including seamless transitions from 3D printing to whatever CNC processes are required.” Some aspects of what that software would look like include managing with the entire process from a single software package and the inclusion of manufacturing knowledge-based assistance for designers and manufacturing engineers, Gibbs added. “It would make standard full associativity to automatically reprocess changes in the design, all the way through the manufacturing processes. It would support the most advanced multiaxis CNC machines, while providing simulation and digital prove-out to
