083: Benefits of Additive Manufacturing for New Inventions

Product Startup · 7 Jul 2021 · 30m

What this episode covers

Steve Grundahl, founder of Midwest Prototyping, explains how additive manufacturing enables 'pop-up manufacturing' for startups, allowing them to produce small batches without the high capital risk of injection molding tooling. He argues that early production runs should be viewed as a feedback mechanism rather than a profit center, using real user data to validate demand before committing to expensive tooling. Grundahl highlights that additive manufacturing allows for complex geometries and rapid design iteration, making it ideal for products with short life cycles or frequent updates, such as GoPro accessories.

    3D Printing and Additive Manufacturing with Steve Szymeczek of Penumbra Engineering

    Steve Szymeczek of Penumbra Engineering explains the practical applications of additive manufacturing for low-to-medium volume production, contrasting it with traditional injection molding. He details the cost-effectiveness of technologies like FDM and HP Multi-Jet Fusion for startups needing 100 to 10,000 units, emphasizing the importance of designing for injection molding even when using 3D printing for prototyping. Szymeczek also discusses the benefits of distributed manufacturing, material limitations, and the role of generative design in creating complex, value-added parts.

    Additive Manufacturing (AM): Injecting Agility and Innovation into Product Development

    Rich Stump, co-founder and CCO of Fathom, discusses the evolution of additive manufacturing (AM) from prototyping to a critical component of agile supply chains. He explains how Fathom uses an outcome-focused, technology-neutral approach to help customers navigate production challenges, citing a case where 12 different manufacturing processes were used to deliver 20,000 parts in 30 days. Stump emphasizes that adoption barriers are often cultural and educational, advising companies to start with 'gateway applications' like jigs, fixtures, or bridge-to-production parts to build confidence before tackling complex end-use components.

    Building the Future: The Journey of The LEGO Group in AM

    Ronen Hadar, Senior Director of Additive Design and Manufacturing at The LEGO Group, explains how the company has used additive manufacturing (AM) for tooling and prototyping since the 1990s, and is now exploring end-use production for consumer goods. He details the development of the famous 'duck' project using EOS FDR technology to demonstrate AM's ability to create complex, functional integrated parts that injection molding cannot easily achieve. Hadar argues that AM is not a replacement for injection molding but a complementary tool, highlighting significant barriers to scaling AM for mass production, including limited material choices, high costs, low machine productivity, and labor-intensive post-processing. Finally, he discusses the critical shortage of AM talent and the LEGO Group's proactive strategy to partner with universities and organizations like Women in 3D Printing to build a future workforce of process engineers, build developers, and data scientists.

    Implementing Additive Manufacturing and Traditional Manufacturing Processes — Special IMTS Edition

    Rich Stump, co-founder and CCO of Fathom Digital Manufacturing, discusses the company's hybridized manufacturing approach, which integrates additive technologies with traditional processes like injection molding and CNC machining. He highlights a specific project where his team produced 20,000 parts in 27 days using 12 different manufacturing processes to meet a Fortune 10 company's tight timeline. Stump emphasizes that additive manufacturing serves as an enabling tool for rapid prototyping, validation builds, and digital warehousing rather than a direct competitor to conventional methods. He also outlines Fathom's strategy post-IPO, focusing on software integration, capacity expansion, and changing customer mindsets through education and tangible project results.

    The Pitfalls and Potential of Implementing AM with Joris Peels & Max Bogue of 3DPOD

    Joris Peels of AM Research and Max Bogue, founder of Wobbleworks and creator of the 3Doodler, discuss the current state of additive manufacturing, arguing that the industry must move beyond hype to focus on frictionless, application-specific solutions and sustainable business models. Bogue details how Wobbleworks bootstrapped the 3Doodler via Kickstarter, avoided premature retail expansion, and found unexpected success in assistive technology for the visually impaired. Peels advises large organizations to implement additive manufacturing through 'sandbox' projects and bottom-up innovation rather than top-down mandates, highlighting the critical role of change management and cultural acceptance.
