58 - The Postprocessing Episode

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 companies to develop innovative and often secretive internal processes. In this episode of AM Radio, Stephanie Hendrixson, Peter Zelinski, Jessica Pompili and Jodee McElfresh share examples of how additive manufacturers solve their varied postprocessing challenges and seek to answer some of the questions around these critical steps. Thanks to listeners who sent questions, left comments or lent their expertise to this episode, including Matt Havekost, Rick Beddoe, Miguel Valenzuela, Konstantin Rybalcenko, Rey Chu, John Whalen and those who responded anonymously.

57 - Does Additive Manufacturing Win the Race? Exploring AM's Production Rate

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 this the measure by which additive must succeed? Pete explores this question.

56 - Applications Reaching the Tipping Point, Semiconductors and Tungsten on the Rise, Costs Coming Down and More From Formnext 2024

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 application examples. Over the course of their time at the show, AM Radio cohosts Peter Zelinski and Stephanie Hendrixson noted more semiconductor applications than ever before, an increased use of tungsten, software developments aimed at solving AM's design bottleneck, various approaches to cutting cost per part, and indications that additive manufacturing has crossed various tipping points expanding where the production method makes sense, and is on trajectory to continue that advance. In this episode of the AM Radio podcast, hear observations from the show floor and takeaways for additive manufacturers.

55 - How 3D Printing Aids Automation, and How Additive Will Reach Farther With Robots

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 automated, solution. And robots are opening opportunities for larger and more complex part production, by providing the motion for a growing number of large format additive manufacturing (LFAM) systems. In this episode of AM Radio, Gardner Business Media Robots & Autonomy editor Julia Hider joins Stephanie Hendrixson and Pete Zelinski to discuss how AM and robots interact, and specific examples of this interaction.

50 - How Model No. Manufactures Sustainable Furniture with 3D Printed Polymers

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 because of a circular economy-focused project that Model No. completed with several partners. And there's one important change to how furniture is made--listen to the episode to learn how (and why) the company's 3D printing capacity has evolved in the last few years.

49 - Trip Report from Innovative 3D Manufacturing

We are trying something new on the podcast! Whenever one of us on Additive Manufacturing Media pays a visit to a manufacturer for the first time, we want to talk about the trip as soon as we return. Why keep this recap to ourselves? In this episode of AM Radio, here is Stephanie Hendrixson getting the full download just after I paid a visit to Innovative 3D Manufacturing in Franklin, Indiana. Innovative does contract production using 12 laser powder bed fusion machines, all from Renishaw. Just part of what struck me is this company's connection to foundry work — not just in terms of process, such as workholding technique, but also in terms of business opportunity, because Innovative is getting work due to foundry leadtime challenges. Listen to our conversation above, or on your favorite podcast app. And for even more on Innovative, read the article I wrote, which is linked below. - Peter Zelinski, editor-in-chief, Additive Manufacturing Mentioned in this episode: Pete's companion article on Innovative 3D Manufacturing, including photos from inside this facility Neighborhood 91, an AM industrial park in Pittsburgh More examples of production AM contract manufacturers
