Agile Talks
In this episode of Agile Talks, guest host Ryan sits down with Bob Mulfinger to explore the rapidly evolving landscape of materials and processes in additive manufacturing and 3D printing. Bob highlights several advancements that have emerged in just the last 18 months, focusing on how these innovations are becoming mainstream and offering new solutions for complex engineering challenges. Key topics discussed include: * High-Performance Filaments: The transition of advanced filaments like PEEK and PPS carbon fiber from niche to mainstream use. * PEEK and Aerospace: The benefits of using PEEK in aerospace and space applications, particularly for low-quantity, complex structures where 3D printing is more cost-effective than traditional machining. * PPS Carbon Fiber: The properties of PPS carbon fiber, including its high heat resistance (over 200°C) and extreme stiffness, which results in a metal-like sound when tapped. * Advanced Resins (SLA): New SLA resins that rival the performance of HDPE (High-Density Polyethylene), offering high accuracy alongside toughness and chemical resistance for automotive and heavy equipment applications. * Metallic Filaments and Organic Design: The process of using powder-infused FDM filament to create metal parts through 3D printing and kiln firing. This allows for "organic designs"—structures that mimic bone by placing material only where it is needed—which are often impossible or wasteful to machine traditionally. * Multi-Material and Sustainable Printing: The ability to print multiple colors and materials simultaneously for functional applications like color-coding. The discussion also covers eco-friendly options, such as recycled and decomposable filaments, to reduce carbon footprints.
