Playing a Big Part: Cummins Impacts Auto Parts Manufacturing With 3D Printing

What if you never had to hear, “They don’t make that part anymore” from your local mechanic?

That fantasy may soon be a reality for car owners thanks to the latest innovations at auto parts manufacturer Cummins. Having already embraced 3D-printing for heavy-duty engine repairs, the Indiana-based company recently sold their first 3D-printed auto part.

Now, they’re looking to disrupt the industry with mass production.

Industry 4.0 in 3D

The landmark part was merely a low-volume bracket, but its creation marks the beginning of Cummins’ strategy to incorporate additive manufacturing and 3D printing at a larger scale.

Investment into 3D printing seems like a no-brainer for Cummins: the Fortune 500 company designs diesel and natural-gas powered engines, power generators, filtration systems, turbochargers, fuel systems, and more.

Embracing 3D printing allows Cummins to “package” multiple, formerly-individual parts into one printed whole. This ensures the production of lighter, stronger, and more reliable parts, especially for components like joint assemblies and weldments. In the testing phase, the ability to just tweak the design file and then reprint also improves upon traditional manufacturing methods.

Beyond more efficient and exact analysis-led design, additive manufacturing also benefits the everyday consumer. According to Kelly R. Schmitz, Executive Director of New and ReCon Parts Engineering, “[3D printing] provides an avenue for customers looking for hard-to-find parts”, and that customers could soon get hard-to-find parts in days or weeks instead of months.

Impacts Beyond The Manufacturing Industry

Cummins’ developments could shake other industries too.

Classic car restorers are all too familiar with getting stuck needing a rare or out-of-production part, especially if they aren’t handy with metalworking themselves. 3D-printed auto parts would not only make the hobby more accessible, it would mean big business for whichever additive manufacturers can partner with well-known parts providers like McMaster-Carr and Classic Industries.

While it might be a stretch to imagine mechanics down at the local Pep Boys playing with 3D printers while your car is getting serviced, the relationship (and speed) between such businesses and their parts providers could change drastically.

Positive impacts could also be seen outside the car industry: Cummins says mass production using 3D printing would help the environment. Not only would there be less waste due to the elimination of the tool and die process, the ability to produce parts locally would cut down on the current environmental costs associated with transporting parts.

As for when we can start expecting parts in a jiffy (and not necessarily at Jiffy Lube), Cummins bets it will be faster than most of us think.

“I’m thinking as soon as five years. We are the start of a really interesting time in manufacturing,” said Director of Advanced Manufacturing Brett Boas. “With this technology, you can really unshackle the designer to do things you just can’t do using traditional forms of manufacturing.”

To prepare, Cummins has already hired their first dedicated additive manufacturing engineer—surely the first of many.

DEVELOP3D Magazine Holding Live Event

Each year, DEVELOP3D, a monthly print and digital design journal, holds a live US event all about product design. This year’s DEVELOP3D Live event will be held this coming Tuesday, October 2nd, from 8 am – 6:30 pm at Boston University.

“We have some really fascinating folks coming to celebrate product design in the 21st Century,” Martyn Day from X3D Media, which runs DEVELOP3D, told 3DPrint.com. “We are especially pleased to have Ti Chang from Crave, Tatjana Dzambazova from new metals 3D printing company Velo3D and Olympian, Jon Owen from Team USA Luge.

“Our day is split with MainStage presentations from designers and the industry, together with a track dedicated to Additive Manufacturing, with all the latest in metals 3D printing.”

Tickets are just $50, and include full access to the conference and all 30 exhibitors, plus refreshments, lunch, and drinks at a social mixer. There will be 20 speakers presenting in two separate streams, and topics include CAD, topology optimization, 3D printing, virtual reality, and product development.

3D Printed Fairing for Ego Corsa

Together, Italy-based CRP Group and its subsidiary Energica have been using 3D printing and Windform materials to develop components for electric motorcycles and superbikes for a few years now. In April, the Ego Corsa electric motorcycle completed its third demo lap, and at the last series of road tests before the first edition of the FIM Enel MotoE World Cup, the 2019 2019 Ego Corsa prototype hit the track with a new 3D printed fairing, manufacturing by CRP Technology with its laser sintering technology and Windform XT 2.0 Carbon-fiber reinforced composite material. The 3D printed fairing update has improved the Ego Corsa’s aerodynamics.

“We have had the fairing available in short time. Thanks to the professional 3D printing and CRP Technology’s Windform composite materials, it is possible to modify motorcycle components – even large ones – from one race to the next ones, in order to test different solutions directly on the track,” said the Energica technical staff.

“This fairing is not only more aerodynamic, but it also has a smaller frontal and lateral section. These improvements led to achieve increase in terms of performance and they led to achieve greater manageability in fast corners.

“The Windform XT 2.0 has once again proved to be a high performance composite material. We are very happy how the 3D printed new fairing behaved during the tests.”

GE Additive 3D Prints Metal Beer Stein

Even though the month of October doesn’t start for another few days, Oktoberfest itself officially kicked off last Saturday in Germany. In order to celebrate the occasion, the AddWorks team at the GE Additive Customer Experience Center in Munich, which opened last winter, decided to take another look at the traditional glass beer krug; what we’d call a pitcher or stein in the US.

The unfortunate thing about glass is that it breaks. Obviously, if you’ve enjoyed too much beer at an event like Oktoberfest, the likelihood of breaking your glass drink container goes way up. So AddWorks decided to create a new prototype beer krug, but instead of using glass, they 3D printed it using a combination of stainless steel and titanium…and the result is pretty impressive.

Take a look at the video below, which stars the head of the Munich CEC (Matthew Beaumont), to see the whole process:

3D Printing News Briefs: August 7, 2018

We’re starting things off on today’s 3D Printing News Briefs with a little business and a little software, before moving on to more cool 3D printing projects and products. NextFlex has announced its Project Call 4.0, and we’ve got a closer look at a 3D print filament recycling system that was introduced at the Barcelona Maker Faire. OnShape has announced the latest updates to its CAD system. A university student 3D printed a car muffler, and Printable Science presents its 3D printed safety razor.

NextFlex Project Call 4.0

Last month, the NextFlex consortium, one of the leaders in the Manufacturing USA network, announced the award recipients of $12 million in funding for the latest round of its extremely successful Project Call program for Flexible Hybrid Electronics (FHE) innovations. This week, the consortium announced the $10 million funding round for its Project Call 4.0, which has a “very diverse scope of needs” that represent gaps in capabilities and technology in multiple application areas. Proposals should focus on several manufacturing thrust areas (MTA), such as flexible battery integration, FHE device encapsulation, evaluating and developing connectors for e-textiles and FHE devices, and advanced 3D electrical design software, among others.

“NextFlex’s Project Call process has proven to be extremely successful. We continuously tackle member-identified FHE manufacturing challenges, and with 31 projects already underway from three previous project calls, we expect this to garner even more interest from the FHE community,” said Dr. Malcolm J. Thompson, the Executive Director of NextFlex. “Topics in Project Call 4.0 build upon successful developments and learning from our previous project calls.”

OUROBOROS 3D Printing Recycling System

The Barcelona Maker Faire was held earlier this summer, and one of the many innovations on display at the event included an all-in-one recycling system for 3D printing called the OUROBOROS. The system shreds used plastic and extrudes the material into a 3D printable filament. According to YouTube user Joan Cullere, the OUROBOROS system includes a prototype shredder with a 24 V motor that’s almost completely 3D printed itself.

In addition to the economic and compact shredder prototype, the OUROBOROS 3D printing recycling system features a user-friendly filament extruder with better cooling, a new spooling system, and an optimized filament path. To see the new system for yourself, check out the video below.

Onshape System Updates

Modern CAD platform Onshape introduced the premium edition of its software in May, and delivers automatic upgrades to the system every three weeks. The latest updates, from July 12 and August 1, include many new improvements to the Onshape CAD system.

For instance, the July 12 update introduced a feature for adjusting the line thickness in drawings, which allows users to define the thickness for tangent, hidden, and visible edges. This update also added a new Drawing Properties panel icon, which replace the wrench icon and includes several new features. The August 12 update made it possible for users to change existing parts or assemblies to a revision, which means every stage of the workflow can be changed. In addition, users can now enjoy significant rebuild time improvements in the system’s complex multi-part Sheet Metal Part Studios. The next updates should arrive on August 23rd.

3D Printed Car Muffler

University student and YouTube user Cooper Orrock was inspired by another maker’s DIY project – a duct tape and cardboard car muffler – to make his own 3D printed version. He designed the two-component automotive part and 3D printed it in plastic; then, with the help of some friends, he prepared the part for installation on a vehicle. This included clearing out some of the holes on the rim of each part so it could be screwed together, and removing the original muffler from the car.

“Part of me thinks that it could possibly melt just because of all the heat from the engine and stuff, but part of me thinks it could work,” Orrock said.

To see if his prediction came true, check out the video below.

3D Printed Safety Razor

Printable Science, which creates “all the science that’s fit to print’ according to its Patreon page, creates all sorts of nifty 3D printed projects, like a socket nut driver, a mini hacksaw handle, and a USB microscope stand. Now, it’s moved on to a 3D printed, four part plastic safety razor.

“Forget the dollar shave club… forget paying shipping and handling… 3D print your own safety razor and be part of the 29 cent shave club,” a member of Printable Science said on the YouTube video.

He explained that the basic design of the safety razor has been mostly unchanged for about 150 years, and that with the design for this razor, you can make your own for just 19 cents. However, this isn’t the first 3D printed razor we’ve seen – in fact, the Gillette Company filed a patent for a 3D printable razor cartridge a few years ago, and was also one of the co-creators of a challenge to design a 3D printed razor handle. To see how Printable Science’s 3D printed plastic safety razor compares, check out the video below.
