On the Ground at Velo3D’s New European Tech Center for Metal 3D Printing

Posted: 21 Jun 2022 08:33 AM PDT

Today, Velo3D (NYSE: VLD) opened a European Technical Center in Augsburg, Germany. The U.S. company has crossed over to Europe, where it can better educate and showcase its capabilities to new and prospective customers. The site also serves as Velo3D’s European headquarters and will house most of its European staff. I visited the opening and had a chance to interview Benny Buller, Velo3D’s CEO, and Dirk Rathsack, Managing Director of European Sales & Technical Sales. 

"Three years ago, we shipped our first Sapphire printer to our very first customer and since then, we've experienced tremendous growth across all of our key industries. Our new Technology Center in Augsburg will support our efforts in growing our presence in Europe in a similar manner and will feature an additive manufacturing solution capable of printing our customers' most ambitious designs,” said Buller at the facility’s opening.

Buller discussed in greater detail the importance of the move, telling 3DPrint.com:

¨In the U.S. we have become a very well-known brand in additive manufacturing. We are recognized for our capabilities there. Here, people don’t know about us. Here, we need to train people, train customers, and build test parts for European customers. Some don’t want parts to go to the U.S. We can now make them in Europe.

Additionally we saw in the U.S. that some of the most knowledgeable and experienced companies with AM know the limitations of the technology. So, when we tell them about Velo3D, they are often the most skeptical. Europe has a lot of history with additive. Europe is a very educated place about additive. There is this Mark Twain quote I really like, "It ain't what you don't know that gets you into trouble. It's what you know for sure that just ain't so.¨ For us to really show people what is possible, we have to show them, in person.”

Buller was also able to elaborate on the company’s choice for Augsburg, Germany. The pretty city near Munich already features its own Technology Center, which includes the Germany aerospace center DLR, as well as cold spray and other 3D printing technologies at the Augsburg Innovations Park. The site is located in the middle of an area with a lot of aerospace activity, with Premium Aerotec and Fraunhofer situated very nearby.

“My team picked Augsburg specifically because it is an important aerospace area and a good location. Many important aerospace businesses are here. Germany is also the largest industrial market in Europe. People here are also very quality minded,” Buller said. “I think the most difficult place for us to penetrate is Germany. That is why we are here. Our biggest competitor, EOS, is here and the next three biggest ones are here also. We have to be here. We have a very clear path in the States. We have a good momentum in the States, as well. Now, we have to crack opportunity in Europe, specifically the one in Germany, Italy, France, and the U.K.¨

In the U.S., Velo3D has a tight application-driven focus. I wondered if that would continue in Europe?

¨For Europe we see a lot of Aerospace, space, commercial aviation and defence opportunities. We also see a lot of possibilities in  oil and gas, power generation, turbo machinery and in nuclear as well. One vertical that we expect to be bigger in Europe is tooling such as die cast tooling and injection mold tooling.¨

In fact, Velo3D already has a launch customer in Europe.

Benny Buller Speaking to the guests.

was able to discuss the types of parts the company hopes to make for which customers, saying:

“We have a lot of interest from our existing clients but also new ones—mainly in space, hydropower, helicopters, aviation, wind energy, and hydropower. We have clients for additive worldwide now. Mastering additive manufacturing for us is a way to serve existing clients but also to diversify. We use this as a tool to bring to existing customers and as an alternative to traditional manufacturing. The most successful parts right now are impellers, mostly shrouded impellers, these are difficult to machine otherwise, especially with more complex geometries.”

The Schoeller-Bleckmann 3D Printing team of Jud and Wutzlhofer, the operators of the first Velo3D machine in Europe.

  would work with customers.

“We are interested in series of parts. We start with a prototype and then develop a part for series. In oil and gas, we can have parts in lots from 10 to 20, but also in the hundreds. Because we have all of the machining and post-processing in house, we can do both machining and additive in one location. We’re now seeing demand in new parts, MRO, tooling, and also in reshoring as companies withdraw from certain markets or want to diversify to reduce risk. We really want to show the possibilities of the additive manufacturing side of our business through an end-to-end process and true manufacturing,”

Dirk Rathsack is leading the commercial and support activities in Europe for Velo3D. We asked him what he aims to do for the company in Europe.

The main challenge for us will be the growing pains: hiring people, managing people, transferring a lot of knowledge. We have already found 14 high caliber people, but we need more. Also, no one knows us well really. Some in France may think that we are a bike company rather than a 3D printing company. So, we have to do a lot of groundwork. We have to tell people who we are, why we exist. We have to establish a foundation, and then build up on that. We are doing a lot of webinars, trade shows, meetings. We have to explain what we can do and do what we say. At the end of the day we have to be a reliable partner. We can’t promise the moon and not deliver. We have to be straight, true, honest and tell the customer what they can expect. We have to deliver on promises.”

In the U.S., Velo3D´s focus Is on large companies that can buy a fleet of Velo3D machines. Germany has those as well, but also has a lot of mittelstand companies, often highly specialized, family-owned firms that are relatively small. Can these use Velo3D too?

“The mittelstand companies are in many ways very innovative and have many disruptive ideas. We hope to find them and let them grow with the technology. Midsized businesses have to be innovative to compete with low cost countries through innovation and technology. We want to help them to do this successfully and ramp up with those companies.”

If the company’s progress in Europe is at all like its work in the U.S., it may soon launch like a rocket. And I’m not just saying that because of all of the space customers taking advantage of Velo3D’s metal 3D printing to produce rocket parts for private space flight.

3D Printer Manufacturer MakerGear Is up for Sale

Posted: 21 Jun 2022 07:00 AM PDT

MakerGear has been making high-quality desktop systems for over a decade. Launching with the simple MakerGear Mosaic in 2011, Rick Pollack´s firm went on to develop sturdy machines with linear rails, strong chassis, enclosures, and a high degree of functionality. Never very flashy or braggadocios, the company was not very well known internationally, but it made some excellent 3D printers. Now, the Ohio-based firm is looking to be acquired.

Long lead times and supply chain interruptions have made it difficult for the firm to fulfill orders and keep printers in stock. Rick and the team have always been direct and honest, so they didn’t hide these issues but were up front about them to customers, even before they bought a new MakerGear product. The company also noted that, previously, the 2018 tariffs on Chinese imported parts hurt the firm, as well. Pollack explained the situation in the following message:

¨MakerGear is a small, self-funded business and the impact of major disruption after major disruption is more than we can absorb….In order to deal with these challenges, we have scaled back operations. At this moment, we are selling our existing printer inventory, trying to maintain a consistent stock of spare parts and providing technical support. As we sell out of printers, we do not know when (or if) we'll be able to restock.

For MakerGear to move beyond this transitional period, we are looking for new leadership. We are seeking an individual, team or entity to take over MakerGear. This could be either through a direct acquisition or it can be done through a transition plan (explained below).

This will require an individual or team with engineering, sales, marketing, and operational experience. MakerGear has solid existing product lines, thousands of customers and we are well established in the Additive industry. Our business model that focuses on building quality products, providing excellent customer service, and making as much as possible in the US has worked well for many years but the challenges over the last four years have seriously hindered our ability to innovate. The new team will need to be able to invest in innovation while engineering costs out of the existing products.

If you are passionate about what MakerGear does, have a vision for what we can be and, most importantly, have the demonstrable ability to execute that vision, we'd like to talk to you.

If you have capital and would be interested in directly acquiring MakerGear, please contact us.

If you have the experience and skills but lack capital, contact us as we are open to working out a transition plan for the right person/team. In other words, for the right person or team, we'll make the transition as painless and low-risk as possible.

MakerGear is currently in year fourteen, we have thousands of customers and we have solid existing product lines. We are seeking the person or team that can take MakerGear beyond what we have been able to accomplish and provide continuity and a path forward for the MakerGear community. If this resonates with you, contact us.¨

The company urges people to email future@makergear.com to find out more. MakerGear is an excellent company, but a difficult business. The firm has been great at customer service, keeping promises and making actual 3D printers. As a true manufacturer of 3D printers, it is far better than nearly all of its competitors. It has never been excellent at marketing or making promises it can’t deliver on. Additionally, MakerGear has lacked the scale and capital to truly internationalize its business and grow. Even within the U.S., it could have had much better distribution and more partners. It could have also been more of a powerhouse online.

From the sturdy M2 to the great M3 and the enclosed, industrial Ultra One, MakerGear has a complete and quality lineup of devices. With some capital and a big marketing and PR push, the firm could definitely find a future for itself. Given its systems reliability and repeatability, as well as general sturdiness, they roughly have two options as an independent firm and several more as an acquired subsidiary.

If MakerGear Remains Independent, It Could…

Go Pro

MakerGear could make machines for manufacturing. Similar to 3ntr, the company could produce robust, repeatable manufacturing devices for factories, service companies, and machine builders. It could develop an excellent Service Lever Agreements and offer to replace machines next day, as well as offer 24/7 support. Truly modular manufacturing devices with high repeatability and reliability would be an excellent play. They’d have to look at how to make even more components in the U.S. and obtain good capital, but there is a lot of growth in this segment.

Go Military

MakerGear could become a specialized manufacturing tool maker for the US military. The company previously won Gold at the U.S. Air Force Rapid Sustainment Office (RSO) Advanced Manufacturing Olympics (AMO). It also has a number of U.S. government clients.

The MakerGear design language and way of making printers is very much about sturdy, reliable machines. A hardened, tough 3D printer built for active deployment would really be a beautiful tool for the U.S. military. No one owns this niche as of now. It’s easy to see how MakerGear could go on to dominate this niche if it managed to make even tougher 3D printers with all or almost all of its components sourced in the U.S.

This would take patience and a long view, but would be a very large business in the long run. Militaries are essentially UPS with guns and around six people serve one active soldier protecting them and all of their stuff in the field. Any FOB repairs, MRO, or similar work could save a lot of money. This could be especially true if MakerGear recycled all of the billions of PET bottles the U.S. military consumes as filament, for example. If engineers could then design battlefield upgrades suggested by soldiers to their kit, they could then be printed out near the frontline to make armies more capable of modifying their kit to fit the war.

If MakerGear Gets Bought, It Could Be…

A Foreign Subsidiary in the U.S.

The most obvious play would be for an overseas company that is seeking U.S. sales, service, and marketing support to buy the firm as its US arm. Similar to why Prusa Research bought PrintedSolid, a foreign business could instantly have U.S. employees, as well as vehicle for selling wares to the U.S. government and better serve U.S. customers. To me this would be a hell of a opportunity to an overseas firm, especially given the speed and low price concerned.

An In-House Manufacturing Firm

Another option would be for it to serve as a defense contractor or in-house 3D printing service and manufacturing unit for large industrial firms. Large businesses, such as auto, engineering, and manufacturing businesses will need to deploy hundreds or thousands of printers across the organization in the coming years. These companies could buy the systems themselves, but currently no one offers the service that they would need to maintain them. So, a conglomerate could build this capacity internally and then use it to serve other customers. Companies such as GM, Ford, GE, Wabtec, Lockheed, Exxon, Lear Corp, Patrick Industries, Dover, Fortive, Parker, ITW, Cummins and more would be well placed to have MakerGear as an internal service to supply it with 3D printers.

A Machine Tool Company

A machine tool company could easily expand its product lineup using the MakerGear 3D printers and sell to its installed base. Companies like Haas, Cincinnati (which is close by and has invested in 3D printing) and Gleason could easily enter the 3D printing market through such an acquisition.

On the whole, this story shows us that you really need to be aggressive in marketing and sales to survive in the current climate. I really like MakerGear and hope that they find the right partner with whom to grow.

COBOD Customer Completes “Largest” 3D Printed Building in Angola

Posted: 21 Jun 2022 06:30 AM PDT

Power2Build, an Angolan additive construction company that works with investors to fund and build affordable homes, has completed its second project. Power2Build built both homes with Danish company COBOD's flagship BOD2 printer.

Moreover, on the first project, Power2Build was the first company to use COBOD's D.fab material, which the latter company developed in partnership with CEMEX, the Mexican building materials giant. On the latest project, Power2Build used the BOD2 and D.fab to build a home well over twice the size of the first: 140 square meters (about 1500 square feet). Power2Build also managed to decrease production time from 48 hours to 30 — a reduction of almost 40%.

The advantage to D.fab is that the Magic Mix supplied by COBOD only constitutes 1% of the total printing material. The remaining 99% is comprised of locally available, regular concrete, which, according to COBOD, can lead to savings of up to 90% compared to materials typically used in 3D printed construction.

As the company points out in the press release, it seems to have no competition in Africa yet, with COBOD responsible for all six of the continent's 3D printed buildings thus far. The BOD2 has been used to build not only Africa's first 3D printed homes, in Kenya and Angola, but also its first 3D printed schools, in Malawi and Madagascar. In the press release, COBOD also notes that its customer, 14trees — which built the first 3D printed school, in Malawi — will, later this year, start work on "a double-digit number" of residential projects in Kilifi, Kenya.

It's significant that sub-Saharan Africa and India appear to be emerging as two regions where additive construction could scale up quickly. For one thing, it suggests that regardless of preference, the technology's best chance to succeed is in the areas that need it most. A 2021 study estimated that the housing shortage in sub-Saharan Africa to be at almost 50 million homes, while the housing shortage in India is estimated to be at over 70 million. Obviously, additive construction alone couldn't fill those gaps. However, thanks in large part to COBOD, it's starting to display real potential as a powerful tool that might aid conventional construction in gradually narrowing the shortages.

Another thing we can take away, from the increasing adoption of additive construction in the places in most urgent need of more housing, is that nonprofit and government subsidies will probably play a critical role in the sector's scale-up. This has also been the case in North America, where, aside from the military, Habitat for Humanity is one of the biggest proponents of the technology. The likelihood that these types of subsidies will continue to grow is reinforced by the fact that there's still so much room to see faster decreases in cost by increasing investment in the industry. That means that funders of 3D printed construction projects will be able to see for themselves, multiple, multi-year reductions in costs and build-times that would be unachievable with conventional methods.

US Army Chooses MELD to 3D Print Metal Military Vehicles

Posted: 21 Jun 2022 06:00 AM PDT

ASTRO America, the American Lightweight Materials Manufacturing Innovation Institute (ALMII), and the United States Army Combat Capabilities Development Command Ground Vehicle Systems Center (DEVCOM GVSC) have partnered to develop a large metal printer for the U.S. Army's Rock Island Arsenal. The printer will be made up of MELD’s Friction Stir Additive Manufacturing technique atop an enormous motion stage from Ingersoll Machine Tools.

The aim of this project is to industrialize the large scale manufacturing of military vehicles. Initially the focus will be on underbody hulls, traditionally hard to manufacture. Welds are key points of weakness in the hulls of tanks and armored vehicles. Specifically in Iraq and Afghanistan, US.. ground vehicles were particularly vulnerable to improvised explosive devices (IEDs) that flipped vehicles or penetrated them. It took far too long for the U.S. to up armor Humvees to resist IEDs. It took much longer to develop mine-resistant ambush protected vehicles that were much more resistant to IEDs through V-shaped hulls.

In wars against irregulars, the U.S. military is too slow to upgrade and improve its kit. If the insurgent can adopt new tactics and develop new IEDs quickly, then the U.S. needs to be able to adapt its vehicles quickly. The military is not set up to do this currently, with procurement being sluggish and cutting edge manufacturing technology not deployed in the most effective way possible.

Ingersoll, you may recall, has previously worked with ORNL to make a large-scale polymer 3D printer. This now serves as the basis for the new metal 3D printing system, which relies on Siemens industrial automation components. The MELD head applies heat of 60 to 90 percent of the metal feedstock to lay down tracks of 1 mm thick and 38 mm wide. In this project, an initial machine will make 1 x 1 x 1 m metal parts.

This is similar to Sciaky‘s electron beam process, wire arc additive manufacturing, and other directed energy deposition (DED) technologies. However, later on, the team will develop a machine with a build volume of 10 x 6.5 x 4 meters. This has perhaps been done on large truss structures for specialized military vehicles, but that is not a capability that has not yet been publicly disclosed.

The printer combines MELD with subtractive machining to finish the part, making it possible to scale up a relatively safe and cheap technology for large components. By relying on MELD, the team avoids having to try to build a football-pitch-sized heated chamber with powder and argon gas, which would be very dangerous if not cost-prohibitive. It also means that the process would work in the open air, without the need to come up with a complex method for heating a part or its surroundings, as some other DED solution would likely require.

Additionally, the team can use cheap feedstock. MELD is also said to achieve good part properties, via good grain structure, part strength and more. Therefore, fully dense parts that suffer less from cracking, porosity, and thermal stress are a possibility with this process.

This project is a huge win for ASTRO America, a brain trust of advanced 3D printing folks that is also involved in the AM Forward program announced by the Biden administration. The team includes LJ Holmes, who was previously at the U.S. Air Force Research Laboratory; Michael Maher who lead a number of key 3D printing projects at the Defense Advanced Research Projects Agency; former Defense Intelligence Agency officer Jason Gorey; and Pentagon manufacturing leading light Neal Orringer. ASTRO board member Jim Williams led Paramount Industries, a very early adopter of 3D printing for defense. The project is also a huge win for MELD, largely overlooked so far by many, but whose efforts in the defense establishment have been consistently nurtured by ASTRO.

This project is a concrete step towards making the U.S. more versatile against threats in the future. By focusing on 3D printing underbody hulls, this collective is pioneering valuable work for the U.S. military.

Launcher Assembles Its First 3D Printed Spacecraft for Upcoming Mission

Posted: 21 Jun 2022 05:30 AM PDT

California-based space startup Launcher is assembling its satellite transfer vehicle and hosted payload platform Orbiter ahead of its first mission, SN1. This flight hardware is scheduled to hitch a ride on SpaceX's Falcon 9 in October 2022, carrying payloads for the company's first ten customers. As Launcher's first-ever spacecraft is getting ready for testing, the company revealed that everything in the assembly (except for the fasteners) was designed and manufactured in-house and that Velo3D's Sapphire 3D printing system produced the most challenging metal components.

When SpaceX SmallSat Rideshare Program carries Launcher's Orbiter satellite transfer vehicle and platform into space, it will deploy up to 400 kg worth of CubeSats and small satellites per mission and precisely place them into whatever orbit their owners desire. However, beginning in 2024, the company will also start offering its own launch service via a liquid-fueled rocket called Launcher Light that will carry 150 kg and 105 kg payloads into low Earth orbit (LEO) and sun-synchronous orbit (SSO), respectively.

Orbiter is the top end of the rocket's three-stage design and was supposed to be the last part of the vehicle to be developed. However, when SpaceX announced in early 2020 that it would begin selling payload space on its Falcon 9 rocket, the Launcher team realized they could make their satellite deployment system compatible with it and other launch platforms and decided to fast-track that part of the project.

Achieving a goal

For Orbiter's propulsion system, Launcher licensed the drawing of a rocket engine for a space-proven turbopump, then set about improving its design using additive manufacturing (AM) technology. When no metal AM equipment provider could produce many necessary components, the team, led by former SpaceX AM manager Tim Berry, turned to Velo3D.

As part of this new challenge, the first part Velo3D created for Launcher was the engine's shrouded impeller, an extremely critical and complex Inconel part that spins at 30,000 revolutions per minute (rpm) and must withstand more than 300 bar of outlet pressure, and is filled with notoriously hard-to-print zero-degree angle surfaces. However, Berry said his team was up for the task and ended up with a finished part that "exceeded all of our performance objectives."

Four of Launcher's Orbiter engines, additively manufactured with Velo3D's technology. Four of Launcher's Orbiter engines are additively manufactured with Velo3D's technology. Image courtesy of Velo3D/Launcher.

Since then, Velo3D went from Launcher's subcontractor to a collaborative partner, especially now that Launcher has invested in its own AM equipment and other metalworking machinery. A move that Launcher founder and CEO Max Haot described as a game-changer, giving the company fast, flexible, and cost-competitive manufacturing advantages. This is crucial for a company that is determined to have its Orbiter spacecraft deliver the lowest cost in the industry for the highest propulsive capabilities. But to achieve that, it was critical for Launcher to have in-house design and manufacturing capabilities.

Berry says that "every time you buy a separation ring, propulsion system, or support structure from a third party, your costs and lead time easily rise by a factor of ten. So instead of the week or so it takes us to design an engine, print, and test it, we would spend maybe two or three months with an outside provider. It's prohibitive."

Until last year, Berry oversaw all AM production and development at SpaceX, including applications, process, and operations engineering, and managed one of the world's largest printer fleets spanning four platforms to support Falcon, Dragon, Starship, and Raptor 2 programs. So if anyone understands how to solve AM challenges in the private space industry, it's probably Berry.

The expert pointed to the fuel tanks as one typical example. He says that if anyone tries to shop around for a space-graded tank able to withstand 3,000 pounds per square inch (psi) of pressure, they will probably hear lead times of eight months to two years, especially if they are custom-made.

"That's not an option in our environment, so as with many of our components, we took the approach of designing based on our available tools," highlights Berry.

In this case, the Orbiter's 22-liter tanks match Sapphire's build volume, so Launcher began by printing the parts out of Inconel. Even though they performed pretty well, Berry and his team wanted to optimize the design by moving to lighter-weight titanium, which worked perfectly for the spacecraft.

"The Velo Sapphire, with its ability to reliably print complex geometry, made it very easy for us to pivot in the face of shifting priorities," said Berry. "That's a benefit of additive technology in general, but especially when you're using a highly-capable print platform."

Having in-house printing capabilities allowed Launcher to continually push for more aggressive designs and higher performance without sacrificing time and money. Today, the company is 3D printing a range of components on its Sapphire systems, including brackets and other secondary structures, combustion chambers, and injectors, all of them at the 24,000 square feet factory floor in Launcher's new Hawthorne, California headquarters. The company is even selling a low-cost, ready-for-integration, 24" separation ring (flight hardware developed in-house to separate Orbiter from the SpaceX Falcon 9) as a component to other startups.

Space access

Now that Orbiter SN1 integration has begun at the company's clean room, it feels like its plans to provide space logistics are finally falling into place. This milestone for the company is a great example of how startups go "from 0 to 1," says Haot; from a research and development stage to a designed, produced, and assembled product in orbit with paying customers. Less than a month ago, Launcher released the list of customers for Orbiter's inaugural flight, including satellite developers Skyline Celestial, NPC Spacemind, and Innova Space, as well as student-run space research groups Cal Poly Pomona's Bronco Space and Stanford's Student Space Initiative.

Due to the in-house design and production of most of the structure, propulsion, and avionics components, Orbiter is offered to its customers at an industry-leading price of $400,000 per dedicated vehicle (excluding SpaceX flight cost). While launch and orbit transfer services are also provided to Orbiter rideshare customers at a per kilogram price of between $8,000 and $25,000 (including SpaceX flight cost), depending on the mission requirements.

According to Haot, the upcoming inaugural flight will illustrate a need for transfer and hosted payload services, one that shared resources available from Orbiter can provide very efficiently. With less than 110 days to go, the upcoming launch is one of the most exciting this year, especially for a company like Launcher, which adopted AM technology from the outset.

GM’s New Cadillac CELESTIQ to Feature Over 100 3D Printed Parts

Posted: 21 Jun 2022 05:00 AM PDT

The Cadillac CELESTIQ is the wildest car name ever—like the name of a futuristic rocket vehicle from Spy Kids. It’s like a name for a space ship or a fever dream robot warrior. In all actuality, it will be a hand-built electrical vehicle (EV) from GM´s Cadillac unit and feature over 100 3D printed parts.

GM will invest $81 million to manufacture the car at its Global Technical Center. The vehicle will be built on GM’s Ultium Platform, which consists of a common architecture, including batteries, drive units, motors and electronics all underpinning Cadillac’s next generation of EV cars. The firm hopes to reap scale rewards from common components and manufacturing processes for EV assembly across different manufacturing sites.

"As Cadillac's future flagship sedan, CELESTIQ signifies a new, resurgent era for the brand. Each one will be hand-built by an amazing team of craftspeople on our historic Technical Center campus, and today's investment announcement emphasizes our commitment to delivering a world-class Cadillac with nothing but the best in craftsmanship, design, engineering and technology,” said Mark Reuss, president of General Motors.

The CELESTIQ will feature over a 100 3D printed parts, both metal and polymer, including structural and cosmetic components. The firm will also deploy 3D printing for jigs, fixtures, and other production tooling. This will help GM's Additive Industrialization Center scale its 3D printing prowess. Previously, GM’s Blackwing CT4-V and CT5-V cars featured one shifter piece, two ducting components, and a harness part, all made with 3D printing. The project also comes off the heels of a recent emergency usage of additive for 3D printed spoiler parts on GM SUVs.

"This investment is a great example of our commitment to GM's EV transformation as we apply our manufacturing expertise to a one-of-a-kind, ultra-luxury vehicle for the Cadillac brand. The advanced manufacturing technology and tools we are utilizing on CELESTIQ will help our team deliver the highest quality vehicles to our customers,” said Gerald Johnson, executive vice president of Global Manufacturing and Sustainability at GM.

We’re seeing a bit of a protracted 3D printing race between the car companies. For a long time, it seemed like BMW, Mercedes, and Volkswagen had a commanding lead over other businesses. Stellantis also has parts in production already. Generally, the US based firms were very far behind.

The European companies are also known to produce many 3D printed jig and fixture components worldwide. BMW revealed that it has produced over $1 million components using 3D printing. That company also used a 3D printed roof bracket for the i8 and had a Mini mass customization program that extensively used 3D printing. Volkswagen has also deployed the technology widely across the firm.

Mercedes probably has the most advanced capabilities in metal printing, due to its extensive Formula 1 involvement. Meanwhile, BWM´s polymer prowess is the most advanced, given the long time involvement that firm has had with powder bed and other technologies. Volkswagen, meanwhile, was ramping up investments in multiple brands to a hereto unseen level.

Now, GM is putting together a very public project managing to best them. Overall, 100 3D printed parts in a car is a significant public commitment. Additionally, relying on several additive technologies at once is complex. At the same time, it is also very advantageous in terms of understanding the technology. But, in terms of volume on existing passenger vehicles, the company has been bested already. I believe that some European automakers may actually have more parts in circulation.

I advocate that companies implement 3D printing in walled-off, manageable projects to see how the technology works. I’m not sure I’d ever want to commit to using these parts in public like this.  If 3D printed structural components are bearing loads continuously, they may be problematic. Given the high variability in part structure, depending on toolpaths and placement in the printer, parts can respond to stresses remarkably differently over time.

Currently, we’re in a time of electrification. This means that the time is ripe to change towards 3D printing as new platforms are made and put into production. Especially with tooling, we know that additive is cheaper and more versatile that competing technologies. On production parts, the technology is still too expensive on the whole. However, this can be fixed if car companies put enough volume behind 3D printed parts and couple this with smart automation.

On the whole, this is a very exciting project. We know from videos that GM’s Additive Industrialization Center has EOS, HP,  and Stratasys machines, as well as those from Formlabs. I can’t wait to see how other firms outdo GM with similar claims, projects, and showcases. I’d love for 3D printing to drive competition and showmanship by large car companies.
