Postprocessing is a necessary part of the additive manufacturing (AM) workflow in almost every instance, because 3D printing alone rarely yields a finished part ready for use. Depending on the materials and processes they choose, AM adopters have to account for depowdering, curing, heat treat, cleaning, dyeing, tumbling, machining and many other post-print operations. Coupled with the high-mix, low-volume production typical in AM, such steps are difficult to automate or optimize — leading many c...

A question from an audience member about competing production rates for a forged metal part that might be made through additive manufacturing instead got Pete Zelinski thinking about production rate in general, and what this rate does and does not tell us about productivity overall. Additive can win a production “race.” An example involving a 1,000-piece production run of parts otherwise made through molding was documented by Formlabs (more info below). However, is a head-to-head comparison like...

Formnext 2024 lived up to its reputation as additive manufacturing’s largest trade show, attracting more than 34,000 attendees to 54,000 m2 of exhibit space. It was also large in the sense of showcasing just how big 3D printing can go, with plenty of showpieces and demos running to illustrate the current scale of large-format additive manufacturing (LFAM) technology. But beneath the robotic arms and towering prints, there were also plenty of new machine introductions, software advances and appli...

Additive manufacturing and robots are parallel technologies, both digitally enabled tools for manufacturing that are advancing in adoption. But they also enable each other. 3D printing can provide the grippers, end effectors and other specialized tooling that robots require to serve production. And robots are driving AM forward as well. Collaborative robots or cobots are being used to tend 3D printer farms, sometimes mounted on autonomous guided vehicles (AGVs) for a fully mobile, as well as aut...

The 2024 edition of IMTS – The International Manufacturing Technology Show welcomed more than 89,000 attendees to Chicago last week. While only a portion of the show’s 1,500 exhibitors were offering additive manufacturing equipment or services, AM nevertheless had a significant footprint at this show. Conversations with speakers, exhibitors and attendees revealed insights about where additive is finding traction now, and where it is heading next. In this episode of AM Radio, I talk with Pete Zel...

Stephanie Hendrixson shares observations from her visit to learn more about two different manufacturing institutes under the umbrella of Carnegie Mellon University. First, she visited the lab facilities at Mill 19, a refurbished steel mill site, used by the Manufacturing Futures Institute. The MFI aims to accelerate the digital transformation of manufacturing, through work that includes things like robotics, digital twins and generative design as well as AM. She also learned about the Next Manuf...

When we first covered Model No. in 2020, the company was manufacturing furniture on its own large-format 3D printers, built to designs directly manipulated by customers through parametric options available on its website. Four years later, production looks a bit different. Gone is the user-facing design tool, as the company has discovered that conversation with customers is the more effective way to arrive at the right designs for its clients. More colors and materials are offered today, in part...

Succeeding with additive manufacturing from a technical perspective has to be followed by succeeding with AM from an organizational perspective. Additive is a different production process entailing different enterprise, workflow and costing considerations, not to mention different personnel, communication and cultural considerations as well. Dr. Tim Simpson and Peter Zelinski talk about all of this: how to organize for success when additive manufacturing is the production process. This episode o...

As a “born digital” technology, additive manufacturing intrinsically relies on data, more so than any other manufacturing process. That data reliance potentially exposes AM users to data security and cybersecurity issues; efforts are underway to help these users protect designs, print parameters, machines and even 3D printed parts. But beyond the dark side of data, figuring out secure ways of storing and sharing data also opens the door to more freely distributing manufacturing, sharing material...

Additive manufacturing offers significant promise for strengthening and simplifying manufacturing supply chains. We glimpsed this during the pandemic, when 3D printers provided a quick response for needed medical components for uses such as ventilators and personal protective equipment. What are the ways AM can answer supply chain problems longer term, and how close are we to realizing this promise? In this episode of the AM Radio podcast, I am joined by Penn State’s Dr. Tim Simpson as we discus...

With the arrival of resources such as ChatGPT and Dall-E, artificial intelligence (AI) is a widespread topic of discussion. But AI has been aiding additive manufacturing for years, to the extent that the applications are coming to seem pervasive. Stephanie Hendrixson and Peter Zelinski talk about the link between AI and AM, both as we see it today and as we expect to see it in the future. What AI and AM have in common is frictionlessness — in terms of offering instruction, as ChatGPT shows, and ...

A sign of the advancing understanding of additive manufacturing: Many of the previous misperceptions have gone away. Or they have at least dramatically declined. Few in manufacturing today believe 3D printing is as simple as "hit print," and most understand that the design of the part determines how well it can take advantage of AM. However, there are still pervasive misperceptions about AM among the manufacturers today who are just beginning to explore it. Tim Simpson and Peter Zelinski talk ab...

Bringing additive manufacturing to scale production also means scaling the workforce trained to design, manage and carry out that production. While some fundamentals stay the same across material and process, learning the intricacies of specific applications and industries takes time. What is the role of the university in preparing the next generation of additive manufacturers? What should industry expect in new hires, and how can companies upskill their existing workforce? And what are the “sof...

3D printing for repair and replacement is an underappreciated but potentially very valuable application for this technology. The ability to add material only where necessary and to do so in an automated fashion allows worn surfaces to be rebuilt with less human labor, keeping items such as aircraft blades in service for longer. Additive manufacturing offers an avenue for manufacturing parts no longer in inventory or production, by skipping over tooling to arrive more quickly (and often, more aff...
