In Ford’s Silicon Valley Lab, Dave Evans creates a custom vehicle gauge and emails the 3D design to Zac Nelson in Dearborn. Nelson uses the MakerBot Thing-O-Matic at his workstation and prints up a physical prototype. The future of research and development is happening right here and now at the desks of these Ford engineers.
Just like laser printers today, expect 3D printers to be commonplace tomorrow. Engineers throughout the industry will have the ability to visualize a design on a computer screen and have the physical prototype show up at a colleague’s desk on the other side of the country in minutes. With this capability, the most qualified experts in each domain can make changes that feed into a tangible model. They can then share a 3D CAD design with the improvements.
“We’ve been shifting from the tangible world to the computer world, and the reality is that a hybrid model works best,” says K. Venkatesh Prasad, senior technical leader, open innovation, and a member of Ford’s Technology Advisory Board, Research and Innovation.
“There is nothing like having a tangible prototype, but it has always been time consuming and expensive to create. Now, at the press of a button, you can have the product or component at your fingertips," he adds. "With a model in one hand, you can then input your changes back into the computer model. The best decisions are made from the highest quality engineer and at the best pace.”
Currently thought of as a do-it-yourself tool for independent entrepreneurs and hobbyists, MakerBot enables users to design and produce products in various plastic materials.
Ford is using this low-cost 3D printing in similar ways to other technology companies, mainly for small developments like shift knobs, gauges and display modules.
Ford is using 3D printing in the manufacturing world, bridging the gap between abstract and practical. Large industrial rapid prototyping machines have made significant gains in the manufacturing world, and Ford is fully invested in the latest commercial 3D printing innovations.
Recently, many of the components for the 3.5-liter EcoBoost engine in the all-new Transit Van were developed with the aid of 3D rapid manufacturing. Cast aluminum oil filtration adaptors, exhaust manifolds, differential carrier, brake rotors, oil pan, differential case casting and even rear axles were prototyped with the technology, specifically utilizing selective laser sintering, stereolithography and 3D sand casting.
Additionally, Ford is a leader in a new variation on this technology: 3D printing with sand allows for the creation of casting patterns and cores with multiple printers in-house.
