Inside 3D Printing Conference in New York – A Retrospective
Inside 3D Printing Conference
In a context that felt a bit like Mr. Smith Goes to Washington, this week 3D printing went to New York for the first ever Inside 3D Printing Conference. Over two full days at the Javits Convention Center in Manhattan, a broad array of industry leaders, innovators, academics and analysts gave keynotes, led seminars, and showed off their latest products to over 3,000 conference attendees. For many in the crowd, this was a crash course on a technology that has been exploding in the public consciousness over the past two years, and for others it was a chance to network, hear from big names in the industry, and get a sense for where 3D printing will go next.
In a role that seemed fitting given his company’s leadership in the industry and status as the conference’s primary sponsor, 3D Systems CEO Avi Reichental opened the conference with the declaration, “Complexity is free” in a 3D printed world. Never before, he underlined, has a manufacturing process been indifferent to geometric complexity, and to him this is the single biggest reason 3D printing will continue to grow and expand into sectors ranging from education to medical devices to automotive and aerospace.
Much of the conference’s focus was on these different segmentations of 3D printing, and breakout seminars throughout the two days took a deeper dive in a variety of subjects. Some of the more memorable seminars explored integrating 3D printers into K-12 education, topology optimization – a complex but very impressive design tool that appears to be a perfect match for 3D printing, consumer desktop and cloud 3D printing, and bioprinting human tissue for medical applications. Longtime industry analyst Terry Wohlers and Shapeways CEO Peter Weijmarshausen also gave keynote addresses highlighting their vision for the industry’s future.

Outside the seminar room the conference also had a distinctly hands-on element. A bustling exhibit hall hosted dozens of booths showing off a variety of consumer and enterprise 3D printers along with more curious technologies like 3D scanners and novel CAD input devices. 3D printing service companies were also eager to engage with potential customers, showing high quality parts available for remote ordering online.
While many sides of the industry were highlighted at the inaugural Inside 3D Printing Conference this week, the underlying theme was very clear: while 3D printing technology may have existed in research labs and niche applications since the 1980s and ‘90s, it is only now beginning to truly change our lives in meaningful ways. And from the number of times speakers said “Nascent,” “Just the first inning,” or “Only scratching the surface” to describe the state of the industry, it is clear that insiders see the eventual impact that 3D printing will make on the world to be profound, far-reaching, and on a larger scale than most casual observers can imagine today.

Topology Optimization in Additive Manufacturing: 3D Printing Conference (Part 5)
Topology Optimization Key to Additive Manufacturing
Topology optimization, an industry term that Wikipedia defines as “A mathematical approach that optimizes material layout within a given design space,” could be a critical motivator to create industrial designs specifically for additive manufacturing. In a captivating presentation at the Inside 3D Printing Conference in New York City, Jim Hassberger and Tony Norton from solidThinking explained how a technology inspired by bone structure research done over a century ago combined with the power of modern computing has led to a new way to optimize load-bearing structural designs.
The results of topology optimization are structures that have outward dimensions identical to normal load-bearing elements such as beams, yet have interior dimensions that look very different from traditionally manufactured parts. In place of triangular or circular voids, these parts have remarkably organic, almost bone-like shapes. The reason is, topology optimization software systematically analyzes the stresses on these shapes and then removes the most superfluous material from the design. This process is repeated over and over by the optimization software, and by the end the computer design leaves only a skeletal interior structure.

So what makes these specially designed parts so special? Why design a part that is so complex? The advantage of parts made with topology optimization is that the same strength characteristics can be created with less material, and this yields a greater strength to weight ratio, an important property across most industries related to transportation. As a practical example, structural rib elements in an Airbus wing designed with topology optimization saved over 500kg in structural weight, which translates to significant cost savings.
The computing power to run topology optimization software became available in the 1990’s, but the technology did not spared as imagined by its creators. Reflecting on its limited success twenty years ago today, Mr. Hassberger and Mr. Norton note that the real difficulty wasn’t in designing parts, but in producing them. Three-dimensional designs created in such a way were often highly irregular with strange voids and curved interior surfaces, making them all but impossible to machine or cast using traditional manufacturing methods. And that’s why they are so excited to reintroduce the technology today. Additive manufacturing, a process in which “Complexity is free” according to 3D Systems CEO Avi Reichental, makes producing these highly complex forms as easy as producing straight, right-angled beams.
While there is still some cost associated with adopting topology optimization, not least of which is a software license starting around $6000, a process that used to be “by PhDs for PhDs” and almost prohibitive to manufacture can now be incorporated into designs after only four hours of training and access to additive manufacturing. And as apparent proof of its value, these designs are already being incorporated into biomedical, Formula 1, UAV and traditional aerospace assemblies.
So will topology optimization be the latest catch phrase at the next Maker Faire you attend? Probably not. However it does promise to demonstrate to industry that additive manufacturing can bring even greater design optimization to existing products, and that is good news for everyone who hopes to see even wider adoption of this paradigm-shifting technology.

3D Printing Conference: Complexity is Free, or Costly?
Brian Evans, Metropolitan State University of Denver professor and 3D printing educator, struggled to get a 3D printing demo to work at today’s Inside 3D Printing Conference in New York City. Showing conference attendees the multitude of open-source 3D CAD and slicing software available, he also exposed the complexity facing those choosing to go the low-cost, open-source route to consumer 3D printing.
“Fail early and fail often,” he sheepishly said to the crowd when his part failed to begin printing. “This is the challenge of using open-source,” he admitted. Mr. Evans also praised higher end consumer 3D printer MakerBot for its easy-to-use user experience.
When asked which slicing software he recommended for slicing 3D files for 3D printing, he responded, “It depends on how dedicated you are. If you really like to tinker, I’d go with Slic3r.” Otherwise he recommends finding another program that takes some of the complexity out.

Keynote Declares “Complexity is Free”: 3D Printing Conference (Part 2)
3D Printing Conference Keynote: Complexity is Free
Avi Reichental, CEO of 3D Systems, the world’s largest 3D printing company, opened this week’s inaugural Inside 3D Printing Conference in New York City with the declaration “Complexity is free” in the world of 3D printing. For the first time in the history of manufacturing, he explained, “The machine doesn’t care how complex of an object it makes.” This was only one of many provocative and forward-looking declarations he made in his thirty-minute keynote to open the conference attended by over a thousand industry insiders, enthusiasts, investors and media followers.
Mr. Reichental’s address focused on the many industries that he sees being disrupted by 3D printing. In design and manufacturing, for instance, he said that two-thirds of professional engineers still do not use 3D printing at all, meaning there is considerable opportunity to further penetrate 3D printing’s traditional marketplace. However, in other industries ranging from medical devices to education to fashion to candy making, Mr. Reichental sees even more opportunity to expand 3D printing’s footprint and create fundamentally new and exciting products and businesses.
Other highlights from Mr. Reichental’s address:
- He predicts the 3D printing industry will grow by 8-10 times in the next decade.
- The combination of higher R&D spending, lower time-to-market, higher complexity, greater democratization, and increased focus on sustainability fuels the rapid expansion of 3D printing.
- No single 3D printing technology will address every solution; therefore multiple technologies need to be advanced.
- “Mass-complexity” of designs will fuel demand for 3D printers in industry as much as “mass-customization,” specifically in strength-to-weight concerned industries such as aerospace and automotive.
- Patient-specific medical devices will become the norm thanks to 3D printing.
While at times Mr. Reichental’s address was clearly promoting the achievements of his own company, he successfully made the point that 3D printing is expanding outward from its core in multiple directions and at a very high velocity. And at very least, he made the case for all the conference’s attendees that to better understand 3D printing is to better understand the future of multiple industries, and indeed a very worthwhile way to spend the next two days.
