3D printing establishes a new era for sustainable manufacturing.
These days, there are several companies that put sustainability in the driver’s seat. If they intend to realize a net zero carbon, fully regenerative economy while reducing overall environmental footprint, sustainability must underscore everything.
Any company aiming to remain competitive and viable beyond this decade is redefining its business priorities around accelerated, expansive change that is also better for the planet. More and more leaders are asking themselves whether the world can be transformed by rethinking their approach to design and manufacturing. However, true resiliency requires looking beyond a company’s own operations to its entire ecosystem.
When HP surveyed global digital manufacturing and 3D printing decision makers in late 2020, an overwhelming majority (89%) said they were changing their business models, and at least nine out of 10 were investigating new and more sustainable supply chain models. One reason is because supply chains are a conduit to widespread sustainable innovation, but only where there’s a willingness to redefine manufacturing paradigms.
GE Aviation has projected cost savings of 35% after switching the production of four land/marine turbine bleed air parts from casting to metal 3D printing.
The aerospace company worked with GE Additive to additively manufacture the four bleed air components, with the cost savings expected to be enough to retire the old casting moulds forever. Harnessing 3D printing, GE Aviation also saw significant time reductions through the conversion process, getting to a final prototype inside ten months, where as it has previously taken between 12 and 18 months when developing turbine parts.
Researchers debut a new technique that proves pills can be designed for individual patients.
The objects are almost beautiful. The surfaces appear faceted and woven, catching the light like ornate jewelry. But they are not jewelry. They are pills, and possibly the most high-tech pills ever designed, in fact. These tablets are artisanal, tuned for just one person, to release a small medicine cabinet of different drugs at the right time.
Developed by researchers at the University of East Anglia (UEA), these pills are produced by a breakthrough in 3D printing. Today, that printing is done in a lab. Tomorrow, scientists suggest, the work might be done by a pharmacist, hospital, or almost any entity other than separate pharmaceutical companies, each of which currently churns out millions of doses of the same drugs in one-size-fits-all pill formats.
There is a tremendous opportunity for additive manufacturing to help overcome the semiconductor shortage, and once again, strengthen supply chains.
Global supply chains have felt the impact of the pandemic for quite some time and continue to face challenges navigating the disruption of production lines even as more regions of the world and business centers gradually re-open and bring more personnel back on-site. The biggest challenge that will remain for the foreseeable future is the shortage of semiconductors, and the signs have been there for months.
Last December, Volkswagen said that semiconductor bottlenecks meant it would produce 100,000 fewer cars in the first quarter of 2021, as its parts makers were unable to secure supplies. Nissan, Renault, Daimler and General Motors are also struggling with the shortage, which may lead to production being reduced by as much as 20% per week.
Shapeways, a leader in powering digital manufacturing, continues to disrupt the traditional manufacturing market through end-to-end digitization and automated workflows that lower manufacturing barriers, alleviate critical supply chain bottlenecks and speed delivery of quality products worldwide. The company’s purpose-built software, proven production capabilities and global network of certified printer, materials and manufacturing partners are transforming manufacturing while boosting supply chain resiliency.
“Global supply chains continue to face massive disruptions caused by unforeseen events—from a traffic jam at the Suez Canal to a year-long pandemic that upended sourcing, procurement and production,” said Miko Levy, chief revenue officer of Shapeways. “Digital manufacturing is the key to meeting escalating demands for supply chain resilience with unprecedented agility and flexibility.”
Ford and HP are looking to make 3D printing technology more sustainable. The giants of industry are teaming up to reuse spent 3D printing parts and powders for vehicle parts, minimizing waste in the process.
Ford and HP are testing the process by making injection-molded fuel-line clips for the Ford F-250 Super Duty. According to Ford, the recycled parts are lighter, less expensive, and more resistant that conventional fuel-line clips. Because the project has panned out successfully so far, Ford is looking to bring its innovation to as many as 10 new vehicles.
The push toward going all-in on EVs creates a natural pivot point to leverage industrial 3D printing, also known as additive manufacturing.
In the past year, we’ve seen a drastic shift across the automotive industry and among consumers with a growing appetite for electric vehicles.
General Motors, Ford and other OEMs have made recent announcements signaling they’re pursuing EVs more heavily. President Biden signed an executive order requiring the replacement of the entire fleet of federal vehicles, about 645,000 cars, trucks, and vans, with U.S.-made electrics.
This push toward going all-in on EVs creates a natural pivot point to leverage industrial 3D printing, also known as additive manufacturing (AM). Here’s why:
A dynamically controlled surface with moving metal platforms can cut material usage in 3D printing by reducing the need for “wasteful” printed supports, its developers have said.
Printing times could also be shortened thanks to the new technique, said the researchers from the University of Southern California (USC).
As conventional 3D printers create custom objects layer-by-layer, they often need to print supports to balance the product. These supports are manually removed after printing, which requires finishing by hand and can result in shape inaccuracies or surface roughness. The materials the supports are made from often cannot be reused, so they are discarded and contribute to the growing problem of 3D-printed waste material.
Ultimaker has released its 2021 3D Printing Sentiment Index (3DPSI), showing that awareness and adoption of 3D printing went up during 2020, and that companies used it in a more integrated way. While the study doesn’t delve into the reasons behind these developments, Ultimaker anecdotally linked them to the challenges posed by COVID-19 and a disrupted global supply chain.
The 3DPSI covers three broad categories: sentiment, awareness, and adoption. Awareness covers how much people know about 3D printing, sentiment covers whether people feel 3D printing is or will be useful, and adoption covers how much people are already using it at their workplaces.
This year’s 3DPSI was conducted online by independent research firm Savanta in December 2020. It polled 2,525 professionals across diverse fields like healthcare, manufacturing, architecture and education. These professionals came from twelve “key markets” across the world: the US, Mexico, United Kingdom, Germany, France, Switzerland, Italy, the Netherlands, China, Japan, South Korea and Australia. Both South Korea and Australia were new this year.
Manufacturing system provider Ingersoll Machine Tools has partnered with aviation company Bell to 3D print a 22 foot-long vacuum trim tool – a mold used for the production of helicopter rotor blades.
The project, which resulted in major lead time savings, was completed using Ingersoll’s own large-format hybrid MasterPrint system, a gantry-based 3D printer with integrated 5-axis milling functionality. According to Ingersoll, the MasterPrint is the largest polymer 3D printer in the world. Designed specifically for the production of extra-large production parts, the system can be found at Ingersoll’s headquarters in Rockford, IL.
“We are continuously testing and advancing MasterPrint in our Development Center” said Chip Storie, CEO at Ingersoll. “Among Ingersoll’s short-term objectives is for MasterPrint to 3D print molds for aerospace that preserve the geometrical properties and tolerances, vacuum integrity and autoclave resilience normally obtained with traditional technology, but with the cost and time reduction only additive manufacturing can offer. The relentless progress our MasterPrint process has made in 2020 has finally made this target attainable.”
