AI in practice: 2 real uses of AI described

What this episode covers

Hosts Daniel and Forbode discuss two engineering breakthroughs: an MIT and BASF collaboration using machine learning to accelerate material discovery, and a partnership between Life Enabled and Entopology using generative design and 3D printing to create affordable, custom prosthetics for developing countries. They detail how AI optimizes chemical formulations and how digital workflows replace labor-intensive casting, significantly reducing cost and time for amputees in places like Guatemala. The episode highlights the shift from manual, expert-dependent processes to scalable, remote, and data-driven manufacturing.

Designentopologyshaves about 2 to 3 entire days off of the process

The company used generative design software to create a breathable, lightweight foam liner for prosthetics, optimizing material placement for structural strength while removing unnecessary material.

“entropology, remember, generative design, helps them know where material is supposed to be and remove it where it doesn't have to be so that it can be more breathable. It can help them generate the shell, the liner, all these shapes so that they're structurally strong enough, minimize the amount of materials so they're lighter and also more breathable.”

Engineering & simulationsuggested 12 that met all the criteria

Researchers used a machine learning system to predict optimal chemical compositions for new materials, suggesting specific samples that met multiple conflicting property criteria like stiffness and strength.

“they automate. They have a machine learning algorithm that will take from you, the user or developer or chemist. Parameters such as what materials you want to experiment with. And then what material properties you want to have. And then it keeps running experiments based on, um, the chemical composition of everything you gave and comes up with suggestions.”

    Why AM and Orthotics & Prosthetics are the Perfect Fit

    Brent Wright, VP at EastPoint Prosthetics and co-founder of Life Enabled, explains how additive manufacturing is transforming orthotics and prosthetics (O&P) by replacing hazardous, non-digital traditional workflows with scalable, data-driven digital processes. He details the shift from plaster casting and carbon fiber layups to pressure casting, 3D scanning, and SLS printing with materials like PK5000 to create flexible sockets that heal wounds and improve comfort. Wright discusses the challenges of scaling care in developing regions like Guatemala through local manufacturing and modular kits, while noting that reimbursement barriers in the US limit the adoption of advanced sensors and actuators.

    Will Your Next Product Be Engineered By An Algorithm?

    Lin Kayser, CEO of Hyperganic Group, explains how his company uses advanced algorithms to shift engineering from a visual, manual process to a code-based software paradigm. He details how this approach allows engineers to generate highly optimized, complex objects on demand, particularly benefiting additive manufacturing by enabling rapid iteration and superior performance in applications like heat exchangers and bioprinting. Kayser argues that this technology can supercharge engineers, bridge the manufacturing skills gap, and transform global trade by shifting the focus from shipping physical components to licensing algorithms for production in localized, automated factories.

    A.I. in Additive Manufacturing with Omar Fergani of 1000 Kelvin

    Omar Fergani, co-founder and CEO of 1000 Kelvin, explains how their AI-driven platform AMAIZE acts as a co-pilot for additive manufacturing engineers, reducing physical iterations by predicting thermal issues and optimizing print recipes. The company, based in Berlin with US operations, focuses on moving AM from prototyping to serial production by treating it as a materials processing discipline, enabling companies to print existing cast designs without modification. Fergani highlights use cases in oil and gas spare parts, partnerships with EOS and Autodesk, and the necessity of AI to address workforce shortages and scale production.

    When Your Shop Is No Longer Bound by Geography w/ Sanjeev Singh Sahni

    Sanjeev Singh Sahni, CEO of Xometry, explains how the company is using data and AI to digitize the custom manufacturing market, which currently has less than 1% online penetration compared to 80% for books. He details the inefficiency of manual RFQs and how Xometry’s platform integrates directly with design software like Siemens to provide instant pricing and supplier matching. Sahni highlights how this digital infrastructure dissolves the traditional 30-to-50-mile geographic radius for machine shops, allowing specialized facilities to take on diverse work such as aerospace and medical devices regardless of location. The conversation emphasizes Xometry's strategy of treating manufacturers as 'partners' rather than suppliers, providing them with tools like a mobile app and AI-driven job recommendations to focus on production rather than sales.

    Step into the Future: Doc Sols’ 3D Printed Revolution in Podiatry

    Travis and Nathan Eadie, brothers behind Doc Sols, discuss their transition from a traditional orthotic lab to a platform-based business using additive manufacturing and AI. They detail the development of their app for foot scanning, the AI-driven prescription engine, and the unique lattice structures printed with EOS TPU powder that mimic human bone anatomy. The brothers also recount the catastrophic flooding of their Brisbane lab in 2022, which submerged their German 3D printer, and their subsequent recovery and scaling plans.
