Ground Zero: Powder Bed Fusion for Prosthetics with David Pierick

Send us a text (https://www.buzzsprout.com/twilio/tex...) David Pierick, a retired Applications Engineer, shares the journey of bringing powder bed fusion technology to prosthetics and orthotics, revolutionizing patient comfort and outcomes through advanced materials. • The initial challenge: proving 3D printed prosthetic components were as good or better than traditional methods • Testing showed printed sockets were remarkably strong—in one test bending the aluminum testing rod before deforming the socket • Patient feedback consistently reported greater comfort with PA-12 sockets, especially when paired with flexible interliners • PA-11 offers superior fatigue properties and better strength-to-stiffness ratio than PA-12, though at higher cost • PK5000 combines nylon stiffness with TPU softness, enabling thinner socket designs with excellent impact resistance • Proper design principles are critical: avoid sharp edges, ensure proper radii on all features, and properly transition corrugations • Future innovation requires thinking beyond traditional manufacturing constraints and adopting true 3D design approaches • Collaborative teams of polymer experts, design specialists, and clinicians are essential for solving complex challenges • New applications could include integrated functionality with shock absorption zones and varying flexibility in a single component Special thanks to Advanced 3D (https://www.adv3dinc.com) for sponsoring this episode.
