Welcome back to the VoxelMatters Podcast—where we shine a light on the people, the technologies, and the big ideas driving the world of additive manufacturing forward. I’m your host, Davide Sher, and today, we’re diving into a story that truly glows with innovation.

Imagine a world where your lighting fixture isn’t mass-produced in a distant factory, shipped halfway around the world, and sitting in a warehouse for months before reaching you—but instead, is 3D printed on demand, near you, for you, and made largely from recycled materials.

That world isn’t coming—it’s already here.

In this exclusive episode, we sit down with Bart Maeyens, Leader of 3D Printing at Signify—the company you might remember as Philips Lighting—to explore how Signify has turned the dream of distributed manufacturing into a global reality.

With over 3.5 million 3D printed luminaires produced across five continents, Signify isn’t just rethinking how we light our homes, workplaces, and cities—it’s reimagining how products are designed, made, and delivered. From the company’s myCreation platform, which lets customers design custom fixtures online, to its automated global printing network that sends digital files to the nearest production hub, this is a masterclass in sustainability and smart manufacturing.

Bart takes us behind the scenes of this transformation—from the early question that started it all, “Can we actually leverage 3D printing to volume?”, to the moment Signify realized that additive could do more than prototype—it could produce.

We’ll explore how the company is using waste materials to create beautiful, functional lighting, how its circular manufacturing model is reducing CO₂ by up to 30%, and why Bart believes we’re entering a decade where “the global economy won’t be as global”—a decade where local, digital production just makes sense.

And of course, we’ll talk about what’s next: the upcoming “Titan” platform that’s set to redefine the boundaries of design and performance in 3D printed lighting.

So grab your headphones, adjust your brightness settings, and get ready to see how Signify is illuminating the future—one layer at a time.

Get ready for an electrifying start to the new season of the VoxelMatters Podcast!

In 2024, we're diving headfirst into the boundless world of additive manufacturing, exploring an array of applications spanning industries, materials, and parts.

To kick off this journey, we've got an extraordinary story to share with you. Brace yourselves for a game-changing narrative about a company that's not just redesigning parts for AM but reimagining them – through code!

Meet LEAP 71, the pioneers of a revolutionary computational engineering approach to part design. They aren't just transforming the way we create some of the world's most cutting-edge products; they're also shaping the future of 3D printing, making it an indispensable cornerstone of tomorrow's manufacturing.

LEAP 71 has wowed us with their mind-boggling creations, working with industry giants like AMCM and the Fraunhofer Institute. While we've heard about parametric and generational design for at least a decade, LEAP 71 has taken a quantum "leap" beyond existing 3D design software.

In this episode, we sit down with the masterminds behind LEAP 71, who also happen to constitute the company’s entire workforce: Josephine Lissner and Lin Kayser. Together, we unravel how they're harnessing software algorithms to craft the next era of exceptionally complex physical products.

Some might not have realized it yet, but creating 3D models—whether for virtual worlds like gaming or for physical use in 3D printing—has recently become a heck of a lot more accessible. This shift is driven by a new wave of AI applications, like Tripo 3D, that can transform text prompts or 2D images into fully developed 3D models.

VAST, the company behind Tripo, emerged from an open-source collaboration among AI and 3D engineers blending virtual and physical 3D worlds.

In this episode of the VoxelMatters Podcast, Founder Simon Song tells us how he is making 3D printing truly ubiquitous.

Robert Higham, Director of AMS, explains how he’s working with Rolls-Royce to transform old Tornado parts into components for the new Tempest fighter, opening a world of opportunities for the Royal Air Force and beyond.

Our guest for this new episode of the VoxelMatters podcast is Jonathan Myer, CEO of APWORKS.

As an engineering company, Munich-based APWORKS has been at the forefront of advanced additive manufacturing for state-of-the-art materials – such as the increasingly popular Scalmalloy, which it brought to market - and applications used in motorsports and aerosapce, since it spun out of Airbus in 2016.

First as Chief Product Officer and now as CEO, Myer has responsibility for product strategy and implementation.

Before joining APWORKS he spent over a decade as Technology Roadmap Owner for Additive Manufacturing at AIRBUS, with responsibility for defining the AM technology strategy at the group level.  

Today APWORKS makes proven aerospace technologies accessible in many different industries. Focusing on metal PBF, the company covers the entire value chain, from optimized component and part design to the choice of

suitable materials, from prototyping to qualified serial production.

We now have the opportunity speak with Jonathan about very latest progress at APWORKS, including the new Genome toolset, which helps customers rapidly implement AM where it makes the most sense, and more generally to discuss about how AM is impacting the aerospace segment today and how it will continue to do so in the years to come.

In today's tech landscape, AI and manufacturing present great opportunities. Randy Altschuler, the founder of Xometry, a digital AI-driven manufacturing company, discusses its motivations, challenges, and prospects. Altschuler was inspired by the importance and potential of manufacturing and saw the opportunity to bridge the gap in the market using digital tools and AI.

One challenge is the lack of awareness about additive manufacturing (AM), which limits industry growth. Increasing awareness and education about AM is crucial for unlocking its full potential. Despite slower growth, the industry is progressing steadily, driven by education and awareness. Integrating AM education from an early age can equip future engineers to utilize these technologies effectively. Additive manufacturing has great allure. AM's automation capabilities make it attractive for reshoring production by countering labor cost advantages in overseas manufacturing.

Xometry creates localized manufacturing marketplaces in multiple languages to enhance resiliency. Their use of machine learning optimizes capacity and offers tailored solutions for customers. Randy envisions expanding the scope of AM, as Xometry becomes a global brand and redefines the manufacturing landscape to make advanced solutions accessible worldwide.

Mass production is the Eldorado of additive manufacturing. It is not easy to achieve and very few companies have been able to cost-effectively produce thousands and even millions of parts using AM technology.

One of these companies is OECHSLER, a major manufacturer of polymer (and ceramic) parts for various key industries, including automotive and sportswear. The German company achieved several

Now, under the leadership of Andreas Knoechel, Head of Program Management Additive Manufacturing, the company is going to the next level, targeting “lot size one” and highly customized products.

These include INSOLO, a 3D printed insole for the orthopedic market (and beyond), as well as multiple bike saddles. In addition, the company recently launched an advanced Online Ordering Platform, which empowers clients to place orders for 3D printed parts quickly and redefines the landscape of manufacturing by combining technology and convenience.

Today we welcome Brad Kreger, the new CEO at Velo3D, the largest US-based manufacturer of metal powder bed fusion 3D printers.

Mr. Kreger joined Velo3D in December 2022 as the Executive Vice President of Operations, and was tasked with transforming the company’s processes, consolidating them after a period of rapid – perhaps even too rapid – expansion.

When Benny Buller, the company’s founder, stepped down as CEO late last year (he remains on the Board of Directors), Mr. Kreger stepped up.

Today he is here to speak with VoxelMatters about his strategy to turn the company around, reassure investors, and “attack” the next phase of massive AM growth, starting with key Defense applications.

He intends to do this by leveraging the “industrialization” experience he matured working at large companies such as Thermofisher, where his responsibilities included taking startups and young organizations that had been acquired and bringing them through the industrialization curve.

In this episode, we will discuss two of the biggest additive manufacturing-related announcements coming from the Paris Air Show.

With these two major and highly strategic announcements, Oerlikon is consolidating its leadership in advancing metal AM part production for aero and space applications.

The company revealed it worked with Airbus to industrialize the AM process for serial production of antenna clusters, which resulted in a €3.8 million contract to additively manufacture these satellite components. In addition, Oerlikon AM and ArianeGroup signed a €900,000 order for the production of 3D printed sets of heat exchangers for the upcoming Ariane 6 rocket launcher.

Oerlikon is investing millions of dollars in developing a strong metal AM service offer that can cater to the extreme requirements of companies such as Airbus and ArianeGroup, even for the most safety-critical parts.

Executive Chairman Dr. Michael Seuss and CTO of Surface Solutions Sven Hicken are with us today to discuss the present and future implications of these deals for Oerlikon and the entire AM industry.

In this week’s episode of the VM podcast, we conversed with Andy Jeffery, a serial entrepreneur with a long-standing history in the 3D printing industry that stretches back to the early nineties. Jeffery’s journey through the 3D printing industry offers a unique narrative - encompassing the founding of companies, exploration of diverse materials, and an ever-evolving interest in sustainability.

Jeffery’s first venture into 3D printing was with a company called Specific Surface, which was one of the first licensees of the Binder Jet 3D printing process from MIT. This marked the beginning of Jeffery’s 3D printing career and spurred him to found numerous companies thereafter, with each new endeavor drawing on his initial experiences.

However, Jeffery’s restless entrepreneurial spirit wasn’t quelled, and his interest in wood led to the establishment of Forust, in 2019. Despite the global pandemic, Forust caught the attention of Desktop Metal and was acquired by them within a year. Jeffery’s work with Forust ignited his interest in sustainability and circular economies.

His current venture, Marvel Labs, focuses on sustainable materials like sawdust, coffee grounds, and seaweed. These materials offer innovative solutions for 3D printing and encourage circularity in the manufacturing process.

Join us as we delve into this absorbing conversation with Andy Jeffery, a pioneering figure who has reshaped the contours of 3D printing over the last few decades.
