In an attempt to build future vehicles or improve upon current models, many automakers have turned to 3D printers to create and test new prototype parts. Considering how important new cars are, you'd think automakers would spare no expense when acquiring such tools, but Ford is proving that 3D printers are not only affordable, but that they could someday become a household answer for many problems.
To show just how fast and easy the process works, Ford shows one of its engineers using a MakerBot 3D printer costing less than US$1,000 to create multiple prototype parts for a manual transmission shifter. This process allows the automaker create new parts to test in the real world. In the past, Ford has used its 3D printers to create everything from small components like the shift knob up to bigger pieces like an F-150 exhaust manifold or brake rotors for the Explorer.
Scroll down to watch Ford's MakerBot create the prototype shift knob out of thin air.
In Transit to 3D Printing Boom, Ford a Major Player in Digital Revolution
3D rapid prototyping enables Ford engineers to create workable parts right at their desks digitally – increasing global efficiency, greatly reducing development time and time to market, and saving cost
Ford is a leader in 3D printing, investing in efforts not only to enable engineers to create an entrepreneurial spirit through experimenting at their workstations, but also investing in one of the newest forms of 3D printing with sand to help develop production-representative parts
Manufacturing and desktop rapid prototyping converge as each Ford EcoBoost® engine – now available in the upcoming Transit Van, all-new Fusion, 2014 Fiesta and full-size F-150 pickup – utilizes the technology to develop parts
DEARBORN, Mich., Dec. 26, 2012 – 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.
"We encourage our engineers to have the same entrepreneurial and creative spirit that started this movement," says Prasad. "When we first got the machine, we made a scaled-down replica Model T and engineers have even made superheroes. We like that people are having fun with it and experimenting for it is that type of creativity that will lead to great uses and discoveries."
Where we are now
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.
The technology enables engineers to quickly create a series of evolving testable pieces with slight variations to develop the absolute best vehicle for mass production. This results in improved efficiency and time to market, reduced time spent waiting on iterations and increased cost savings.
Examples of 3D sand printing include:
C-MAX, Fusion Hybrid: Rotor supports, transmission cases, damper housings and end covers for the new HF35 hybrid transmission built at Van Dyke Transmission Plant in suburban Detroit
Escape: EcoBoost four-cylinder engines in the 2013 Escape built at Louisville Assembly Plant
Explorer: Brake rotors for the 2011 Explorer built in Chicago. The rotors were modified late in development to address a brake noise issue discovered in durability testing
F-150: Exhaust manifolds for the 3.5-liter EcoBoost built in Cleveland and used in F-150
Where this could lead
In the not-so-distant future, if a part breaks on your refrigerator, you may be able to scan the barcode or a model number, take the information to an in-home rapid manufacturing machine, and actually print up a useable replacement piece.
"Many have referenced this technology as ushering in a third industrial revolution," says Harold Sears, Ford additive manufacturing technical specialist. "While that is yet to be determined, we do know manufacturing is continuing to go digital, the speed of these technologies is increasing, and the variety of materials is expanding. This all leads us to believe the potential of micro-manufacturing presents great opportunity for the manufacturing industry overall."
