OTW POD Episode 15 - 3D Systems

In this episode, TJ sits down with Ben Johnson from 3D Systems, who leads their medical device division and brings a fascinating perspective shaped by his journey from chemical engineering into the cutting edge of additive manufacturing. Ben shares how his early work on drug-eluting stents and transcatheter heart valves led him to discover the transformative potential of 3D printing when he needed patient-specific anatomies for bench testing, ultimately bringing him to 3D Systems in 2014.The conversation explores the evolution of additive manufacturing in orthopedics, from the company's founding in the mid-1980s with the invention of stereolithography to today's sophisticated capabilities across titanium, PEEK, and cobalt chrome materials. Ben provides valuable insights into the current market dynamics, explaining how titanium has surged from being overshadowed by PEEK a decade ago to now holding roughly half the spine market, driven by its superior osseointegration properties when 3D printed with porous structures.They dive deep into emerging technologies, particularly the exciting developments in HA-coated PEEK implants that combine the mechanical advantages and radiolucency of PEEK with enhanced biological integration. Ben discusses 3D Systems' recent white paper demonstrating successful osseointegration in both cortical and cancellous bone, and why he believes this technology will see heavy research and investment over the next five to ten years. The conversation also addresses the realities of personalization in orthopedics, with Ben offering a measured perspective on why point-of-care printing in hospitals faces significant regulatory and cost hurdles, while centralized hybrid models show more immediate promise.Perhaps most valuable for listeners is Ben's explanation of how 3D Systems partners across the entire spectrum of companies, from startups with napkin sketches to major OEMs. He details their comprehensive capabilities, from concept ideation and prototyping through validation, manufacturing, and even technology transfer, emphasizing their mission to solve unmet clinical needs whether that's faster osseointegration, oncology reconstruction, or supply chain challenges. It's a compelling look at how a manufacturing partner can accelerate innovation from concept to commercialization in orthopedics.
