Ford is teaming up with HP in a bid to reuse spent 3D printed powders and parts, closing the loop and turning them into injection molded vehicle parts – described as an industry first.
The firms say the resulting injection molded parts are better for the environment with no compromise in the durability and quality standards Ford and its customers demand.
The recycled materials are being used to manufacture injection-molded fuel-line clips installed first on Super Duty F-250 trucks. The parts are said to have better chemical and moisture resistance than conventional versions, are 7 percent lighter and cost 10 percent less. The Ford research team has identified 10 other fuel-line clips on existing vehicles that could benefit from this use of material and say they are migrating it to future models.
Debbie Mielewski, Ford technical fellow, Sustainability, said: “Many companies are finding great uses for 3D printing technologies, but, together with HP, we’re the first to find a high-value application for waste powder that likely would have gone to landfill, transforming it into functional and durable auto parts.”
HP says its 3D printers are designed for high efficiency, with systems and structures to minimize the excess material they generate and reuse a greater percentage of the materials put into them. Working with Ford, which uses HP’s 3D printing technology at the company’s Advanced Manufacturing Center, the team created this solution that is said to produce zero waste.
“You get more sustainable manufacturing processes with 3D, but we are always striving to do more, driving our industry forward to find new ways to reduce, reuse and recycle powders and parts,” said Ellen Jackowski, chief sustainability and social impact officer, HP. “Our collaboration with Ford extends the environmental benefits of 3D printing even further, showcasing how we are bringing entirely different industries together to make better use of spent manufacturing materials, enabling a new circular economy.”
For its part, Ford says it is developing new applications and utilizing a multitude of different processes and materials for 3D printing, including filaments, sand, powders and liquid vat polymerization. The company already employs 3D printing for a variety of low-volume commercial vehicle parts, as well as fixtures used by assembly line workers use, saving production time and enhancing quality.
Ford has declared a goal to achieve 100 percent sustainable materials in its vehicles.
“A key to achieving our sustainability goals and solving the broader problems of society is working with other like-minded companies – we can’t do it alone,” Mielewski said. “With HP, we defined the waste problem, solved technical challenges and found a solution in less than one year, which is something in which we all take pride.”
Three other companies helped Ford and HP make the project outcome possible.
The firm SmileDirectClub, was one. It’s described as a “next-generation oral care company with the first medtech platform for straightening teeth” and it “operates the largest facility of HP 3D printing systems in the U.S.”. The company’s fleet of more than 60 HP 3D printers enables the production of more than 40,000 aligners a day. The used 3D printed parts are collected and recycled with HP to increase volume for Ford. Resin producer Lavergne, a longtime recycling partner of HP, transforms those molds and discarded powder from Ford’s HP 3D printers into high-quality recycled plastic pellets, suitable for injection molding. The pellets are then molded into fuel-line clips by Ford supplier ARaymond, which designs, engineers and manufactures assembly systems.
