Member Question: Additively-Manufactured Product Launches

Earlier this year, a Member sent us a question: What portion of new products introduced in joint reconstruction and spine are additively manufactured?

This question had been on our radar for some time. Additive manufacturing (AM) has generated more interest than any other topic we’ve written about or presented at OMTEC in the last two years. Internally, we’ve wondered, is it just buzz or are companies actually adopting the technology? To investigate, we tracked products launches and regulatory announcements from January 2015 to 2017. Nearly two dozen companies were mentioned in ORTHOFLASH® during this time period. For your benefit, we’ve listed these companies, their market segments and products below. We’ve also included executive insight that we found to be valuable.

Our analysis leads us to state that >5% of joint reconstruction and spine products launched or about to be launched in the last two years incorporate additive manufacturing.

Work still needs to be done. This is not a comprehensive list of companies using the technology, nor does it represent all AM-related products on the market, but it is a start. We expect that more device and supplier companies will adopt additive manufacturing once more regulatory guidelines are established and patient outcome evidence is generated.

Spine | Announced FDA 510(k) clearance (and subsequent launch) of Tritanium® PL, a highly-porous posterior lumbar cage made via 3D additive manufacturing.
Spine | Results from a pre-clinical interbody fusion study of Stryker Spine’s 3D-printed Tritanium PL Interbody Cage demonstrated statistically superior range of motion, bone in-growth profile and greater average construct stiffness vs. PEEK and titanium plasma-sprayed PEEK cages.

“For the foreseeable future, at least the next three, four years or so, our focus is on innovative new products and not replacing our existing products with 3D printed products. The pipeline of innovative new geometries that can’t be made without 3D printing is the area of focus. It’s not about trying to replace our products and drive down cost. Over time, ten years from now, that could be the case, but in the near- to mid-term, it’s really a focus on innovative new products.”
—William R. Jellison, Stryker’s Vice President and Chief Financial Officer (retired)

“We're seeing [3D printing] impact two different divisions of Stryker: our knee business as well as spine, and we have a huge line-up of other divisions with ideas and prototypes to get into 3D printed titanium products.”
—Kevin Lobo, Stryker’s Chief Executive Officer


Zimmer Biomet (LDR)
Spine | Poly-Shape, a French manufacturing company specializing in laser sintering, entered into an exclusive agreement with LDR. The agreement combines LDR’s spinal focus and approach to implant design with Poly-Shape’s proprietary, additive manufacturing methods. The agreement was signed in 4Q15. Initial projects are underway, with the expectation to launch newly-designed spinal implants produced with Poly-Shape technology as early as mid-2017.

“What we are definitely looking for is patient-specific implants; how do we make implants which are complicated—not necessarily off the shelf—but where we would be taking information from a patient’s image and making an implant for that. We see a big application in that field.”
—Mukesh Kumar, Ph.D., Director, Advanced Process Technology, Zimmer Biomet


Other notable comments:

Andy Christensen, Additive Manufacturing Veteran
FDA first cleared an additively-manufactured 3D printed metal implant in 2010, and implants were 3D printed in Europe prior to that. FDA says that they’ve cleared ~80 devices that are 3D-printed medical devices. I think from their standpoint that this includes plastic parts as well as metal parts. Many experts predict that 3D printing in medical implants is going to grow by 20%+ over the next 5, 7, 10 years.

Bob Kinsella, President, Kinsella Group
Based on his perspective from working with manufacturers that are experimenting with it, Kinsella observed that additive manufacturing won’t be fully realized until companies get past viewing it as simply a tool and implement it for actual production of parts. Once that takes place, the technology or the human expertise associated with it will be ripe for more M&A activity at device and supplier company levels.
