    When Production Overtakes Prototyping: Materialise’s Next Phase of AM

    In this episode of Additive Snack, Fabian Alefeld sits down with Bart Van Der Schueren, CTO of Materialise, to discuss additive manufacturing's (AM) evolution from a prototyping tool to a true production technology. Bart shares his journey into AM through early stereolithography research at KU Leuven and reflects on Materialise's origins as a small service bureau that quickly realized it needed its own software to automate data preparation and workflows. Those early efforts eventually grew into the three pillars that define Materialise today: manufacturing, software and medical applications. The conversation explores a major milestone for Materialise, as serial manufacturing volumes in its manufacturing business have now surpassed prototyping. Bart explains what's driving that shift, where AM is gaining traction fastest, and why industries such as hearing aids, dental, drones and aerospace are moving at different speeds. The discussion also examines the growing role of artificial intelligence in manufacturing, from design optimization and simulation to in-situ quality control, automated workflows and reducing the cost of new product introduction. Bart shares how Materialise is positioning itself for the next stage of AM growth while helping customers scale production in highly regulated industries. 01:59 Bart Origins in AM 04:49 Materialise Early Model 07:28 Three Pillars Emerge 09:59 From Prototypes to Parts 15:07 Serial Production Milestone 20:22 Industries Driving Adoption 23:13 Aerospace Slow Burn 27:24 Disruptors Drones and Agile 31:02 Iterative Printing Workflow 32:19 AI Driven Rapid Iteration 34:11 Mass Customization With AI 38:47 Design AI Beyond Hype 42:06 AI For In Situ Quality 45:28 NPI Costs And Scaling 48:16 Materialise Strategy Ahead 55:00 Industry Outlook No Return

    AM as a Moat: How Annihilator Created a Competitive Advantage in Broadhead Manufacturing

    Fabian Alefeld interviews Brandon Brodie, co-founder and CEO of Annihilator Broadheads, about how an Idaho elk hunt and a lost bull sparked a new broadhead concept sketched by Brandon’s future partner Micah. They describe turning the 2D sketch into plastic CAD prototypes via Boise State, a makeshift “wind tunnel” test using Instant Pot steam, and early performance goals of flight, penetration, durability, and lethality. Field and improvised tests (steel drum, long-range accuracy, animal kills) plus third-party fluid dynamics modeling suggested Annihilator’s design created unusually large high-pressure and low-tension effects.   After major supply failures with investment casting and metal injection molding - causing shortages, high scrap rates, and lost dealers - Brodie brought manufacturing in-house, adopting metal laser powder bed fusion, improving repeatability and enabling new geometries like the Katana. He outlines ongoing innovation, potential adjacent products, and plans to leverage Annihilator’s additive capabilities for partnerships and contract manufacturing.  02:26 Elk Camp Origin  06:43 Sketch to Prototype  11:36 Instant Pot Wind Test  14:44 Performance Pillars  18:41 Steel Drum Proof  22:45 Real Hunt Validation  26:45 Fluid Dynamics Breakthrough  30:41 Engineering Led Marketing  33:32 Manufacturing Growing Pains  34:27 Industry Award Surprise  35:53 COVID Demand Crunch  36:54 Casting Supplier Failures  39:40 MIM Tooling Disaster  42:30 Additive Breakthrough  46:35 Learning Metal Printing  49:55 Repeatability and Materials  52:56 Katana Broadhead Innovation  57:49 Scaling R&D Team

    AI Is Getting Hot: Can Additive Manufacturing Help Cool It Down?

    Host Fabian Alefeld interviews Professor PS Lee, Head of National University of Singapore Mechanical Engineering & Program Director of STDCT, and founder of CoolestDC, about heat as a key constraint in AI infrastructure as data centers shift from CPU-heavy to GPU-dense systems with higher power density, hotspots, and bursty workloads. Lee explains why cooling must be treated as an integrated “chip to grid” system spanning cold plates, racks, CDUs, piping, controls, and operations, and discusses single-phase versus two-phase direct-to-chip liquid cooling and the added need for condensation in closed loops.   Professor Lee describes how additive manufacturing (AM) enables complex fin structures and unibody cold plates that reduce leakage risk, lower junction temperatures (~10°C), cut pumping power (60–70%+), and reduce material use, while requiring TCO evaluation. At NUS’s live testbed (22 liquid-cooled racks, ~500 kW), AM cold plates are being deployed and show promising thermal, power, and compute-performance improvements; future work includes two-phase cooling and broader system-level heat rejection, warm-water operation, and waste-heat reuse, plus a discussion of challenges and potential AM roles in space-based data centers.  02:13 Meet Professor Lee  05:26 Chip To Grid Cooling  10:22 Liquid Cooling Maturity  14:15 Two Phase Explained  18:12 Cold Plate Tradeoffs  20:40 AM Unibody Cold Plates  24:41 Benchmarking AM Gains  30:18 AM For CDUs  34:13 Inside STDC Testbed  38:09 Reliability And Leakage  39:00 Next Phase Roadmap  42:31 Orbital Data Centers

    Why AM and Orthotics & Prosthetics are the Perfect Fit

    Fabian Alefeld interviews certified prosthetist/orthotist and EastPoint Prosthetics VP Brent Wright about his career path into O&P, his shift from being anti-digital to adopting scanning and additive manufacturing, and the impact on patient care and global access. Wright describes traditional fabrication workflows (casting, plaster positives, vacuum forming thermoplastics for orthoses, and carbon fiber/resin layups for prostheses) as artistic but time-consuming, hazardous, and lacking records.  His digital journey accelerated after a Guatemala trip with Life Enabled highlighted the need to scale care; he focused on scanning, digital modification, and later powder-bed fusion, moving toward SLS with materials like PK5000 and TPU. He emphasizes pressure casting for prosthetic sockets, the value of digital records for insurance, and how AM can change socket “dynamics” to improve comfort and heal wounds.  The discussion also covers RADii’s data-driven fitting approach, Life Enabled’s mix of traditional and 3D-printed solutions (including pediatric feet), modular “kit” concepts for developing regions, and barriers to sensors/actuators in the US due to reimbursement. 02:33 Brent Origin Story 09:30 Why Go Digital 11:17 Scaling Global Access 17:32 Traditional O&P Workflow 20:02 Casting And Fabrication Steps 24:07 Digital Workflow And Scanning 33:22 Benefits Of Digital Records 36:36 Flexible Liner Heals Wound 40:47 RADii Data Meets Craft 46:06 Life Enabled Model 01:01:50 Democratizing via Manufacturing 01:08:01 Sensors vs Simplicity
