Not too long ago, our govt editor Joris Peels defined that, within the automotive trade, 3D printing is usually used most frequently for distinctive, mass-customized elements; very low-run manufacturing gadgets; “some weight financial savings components and intensely low-volume components on passenger vehicles.” Which may be altering, nonetheless, as he talked about in early 2021 that the “automotive trade is changing into enthusiastic about 3D printing.”
Whereas it could not all the time seem to be the know-how has fashioned as sturdy a foothold in automotive because it has in different sectors, 3D printing truly is used very often for some of these functions. We requested some trade specialists for his or her ideas on what AM within the automotive trade will appear to be this yr.
“Though not mentioned a lot, I’m assured that additive manufacturing for prototyping and tooling continues to be fairly vibrant,” 3D printing guide, author, and presenter Todd Grimm instructed 3DPrint.com. “The noticeable change in 2021 was within the space of collection manufacturing. The tide appears to have shifted as OEMs and suppliers create improvements and provoke disruptions that sidestep what has stymied additive manufacturing for years: unit value and annual manufacturing charges. I consider that the momentum of final yr will carry ahead in 2022 and past such that automotive functions for additive manufacturing aren’t relegated to racecars, hypercars, and ultra-high-end autos.”
As SmarTech Evaluation talked about in its final report on additive manufacturing for automotive components manufacturing, automotive 3D printing represents a $9 billion income alternative.
“This report assesses the general alternative for additive manufacturing within the automotive trade, together with upcoming steel and polymer processes and supplies which might be going to realize wider adoption throughout the 10-year forecast interval. These embrace main polymer in addition to new high-throughput steel and polymer AM applied sciences comparable to digital mild synthesis from Carbon, multijet fusion from HP, in addition to new certain steel filament and upcoming steel binder jetting processes,” SmarTech wrote.
Talking of HP, Guayente Sanmartin, World Head of HP’s MJF enterprise, stated that automotive is one among many industries “present process digital transformation” by shifting shortly to extra connectivity in autos, “provide chain localization, and provider consolidation.”
“HP is working with dozens of automakers, suppliers, and manufacturing companions world wide to design and develop sustainable components from prototyping to manufacturing,” Sanmartin defined.
For instance, in late 2021, Japanese CAD and 3D printing firm SOLIZE introduced that it will be utilizing HP 3D printers to make out-of-production end-use spare components for NISMO, which is Nissan’s tuning and motorsport division. The explanations for utilizing the know-how included versatile design, a digital stock, and sustainable on-demand manufacturing that helps cut back industrial waste and carbon dioxide emissions.
“On daily basis we’re seeing rising traction and extra mature 3D printed functions throughout many various industries, particularly in automotive. Automakers are forging forward as they broaden their use of 3D printing, changing conventional tooling with 3D printed variations, quickly iterating with useful prototypes, designing fully new personalised elements, and increasing short-run manufacturing of absolutely useful ultimate components,” Sanmartin continued. “Our clients are benefiting from the industrial-grade capabilities – effectivity, repeatability, half high quality, value effectiveness and extra – supplied by Multi Jet Fusion to ship on these rising alternatives.”
Sanmartin additionally referenced a latest US Council of Automotive Analysis (USCAR) report, which “outlines a roadmap for integrating additive manufacturing extra broadly into the trade’s high-volume manufacturing processes.” USCAR mentions that 3D printing “has but to turn out to be built-in into high-volume manufacturing processes” within the automotive sector, regardless that that trade has been utilizing the know-how for many years, as a consequence of challenges like costly tools, supplies, and operations, and a scarcity of the “pace and reliability wanted for top quantity functions.” However, the report additionally discusses the potential for progress, and potential advantages, of 3D printing within the automotive trade.

“We’re very excited in regards to the promise of additive for mass steel manufacturing, the quickest rising section of the normal 3D printing market. Based mostly on HP’s core Thermal Inkjet capabilities, our Steel Jet know-how permits the manufacturing from excessive quantity runs to really distinctive high-value components. We consider our modular system and built-in workflow delivers higher productiveness, decrease half value, and superior high quality,” stated Didier Deltort, the President of HP’s Personalization & 3D Printing enterprise. “For instance, I’m more than happy with our developments with Volkswagen. Volkswagen shared a latest use case highlighting HP Steel Jet produced components for the A pillar of the T-Roc Cabriolet. The structural components have handed crash take a look at certification and weigh virtually 50 p.c lower than typical elements. Auto producers are among the many most demanding on the earth. That is the primary time an automaker is utilizing steel binder jetting for structural elements. We’re persevering with to validate manufacturing functions with companions and clients as we transfer towards broader business Steel Jet availability in 2022.”
One other advantage of 3D printing, as talked about earlier, is sustainability, which HP has lengthy thought of a main precedence.
“As corporations look to fulfill the demand for extra personalised merchandise they’re additionally trying to ship extra sustainable merchandise and packaging. When HP surveyed world digital manufacturing and 3D printing resolution makers in late-2020, an awesome majority (89%) stated they have been altering their enterprise fashions, and at the least 9 out of 10 have been investigating new and extra sustainable provide chain fashions,” Deltort stated. “3D printing is offering extra sustainable manufacturing strategies from sustainable design that removes extra weight and waste to native manufacturing that results in a decrease carbon footprint.”

Not too way back, HP introduced that it was partnering with Ford to change how 3D printing waste is reused within the automotive trade. The 2 arrange a sustainability program that turns 3D printed components and powder into injection molded fuel-line clips, which is able to first be put in on Ford’s Tremendous Obligation F-250 vans.
Desktop Steel is one other firm targeted on sustainability in 3D printing, as the corporate’s Co-Founder and CTO Jonah Myerberg instructed us that corporations will likely be pushed to “embrace the 4th industrial revolution” as a consequence of sustainability expectations being launched by state and federal governments.
“The automotive trade has seen the best impression of inexperienced initiatives – from EV mandates within the state of California, to President Biden’s Construct Again Higher plans. This may bleed into different industries in 2022 together with retail, client items, aerospace, healthcare and extra—main corporations to extra absolutely embrace and understand the 4th industrial revolution,” Myerberg instructed 3DPrint.com.

Desktop Steel made headlines not too long ago when an unnamed main German automaker put in a $7.9 million order for its binder jetting additive manufacturing programs; the corporate’s 3D printers have been utilized by Ford as effectively. Myerberg additionally famous that as corporations proceed to face shortened provide strains, they’re on the lookout for new methods to deal with these challenges, and applied sciences like robotics, 3D printing, and AI “will play a key function.”
“Shifting into 2022, producers will look to embrace these applied sciences to assist shorten their provide strains, reimagine the manufacturing facility, and revolutionize how world enterprise is completed,” Myerberg stated.
The corporate’s CEO, Ric Fulop, echoed these ideas, noting that 3D printing will give corporations, together with these within the automotive sector, “the chance to re-shore manufacturing.”
“There was huge progress and consolidation within the additive manufacturing house, which is offering corporations the power to rethink their manufacturing operations and re-shore them again to the U.S. because it turns into extra inexpensive,” Fulop instructed us. “Now, corporations have entry to additive manufacturing wherever they need the components made and don’t must depend on consolidation and transportation internationally. This may lead to a rise in jobs inside the US, an emphasis on training for the workforce, and a lower in reliance on lengthy provide chains.”

Dr. Jeffrey Graves, the President and CEO of 3D Techniques, additionally agreed.
“As we enter 2022, I consider we’ll proceed to see AM play a crucial function in remodeling manufacturing workflows and provide chains. Important delays in logistics are hampering organizations’ means to ship services in a well timed trend. Having the ability to manufacture all crucial elements on the level of meeting, or level of care can streamline these actions,” Dr. Graves stated.
“I additionally anticipate AM’s means to allow mass customization will deliver huge worth to a number of functions to learn each industries and other people. From automotive to aerospace, semiconductor capital tools producers to service bureaus, and healthcare suppliers, AM has the ability to enhance efficiencies by concurrently producing quite a few distinctive, end-use components.”
Lastly, Nexa3D’s Co-Founder, Chairman, and CEO Avi Reichental believes that 3D printing within the automotive trade is certainly right here to remain, each in 2022 and past.
“Definitely the automotive sector stays among the many largest for 3D printing,” Reichental instructed 3DPrint.com. “The much less glamorous components of auto manufacture, tooling, jigs, and fixtures, will see extra adoption. These might be made particular for a specific make and mannequin, considerably rushing up the time it takes to construct vehicles. Widening choices for casting will even see polymer 3D printing take a bigger function within the automotive trade, as steel components might be made at decrease value than direct steel AM and with elevated complexity in comparison with conventional manufacturing.”
