Martin Eichenhofer is the CEO & co-founder of 9T Labs, a company that was spun out of ETH Zürich in Switzerland. 9T Labs specialises in providing software solutions and manufacturing equipment for producing high-quality and high-performance composite materials using 3D printing. By marrying the worlds of composite materials and 3D printing, 9T Labs is taking advantage of the superior material properties of composite materials and combining these with the geometric fidelity facilitated by 3D printing. As a result, components that were previously unfeasible to be manufactured using composite materials, either from a technical or cost perspective, are now within the realm of the possible. What is unique about 9T Labs is that the company combines their hardware for 3D printing composite parts with a bespoke optimisation software in order to maximise a component's performance, both in terms of structural design and manufacturing quality. Furthermore, it has been historically difficult to print continuous fibre composites at high quality with a low void content. 9T Labs, however, has patented a process that allows printing at a void content of below 1 percent, which competes with conventionally manufactured composites. So, in this episode of the Aerospace Engineering Podcast, Martin and I discuss:

• his background as an engineer and how his PhD research led to 9T Labs
• the challenges and benefits of 3D printing composite materials
• 9T Labs’ unique approach to 3D printing composite materials
• some of the applications the company is currently working on
• and much, much more.

Chris Voorhees is the founder and president of First Mode, a Seattle-based company that is designing and building technology for extreme environments off and on planet Earth. Chris has decades of experience in the implementation of robotic systems for the exploration of deep space. His notable experience includes his work as a mobility systems engineer for NASA's Spirit and Opportunity rovers and lead mechanical engineer for NASA's Curiosity rover. For his efforts, Chris received NASA's Exceptional Achievement and Exceptional Engineering Achievement medals. Today, Chris oversees the design, development, and deployment of engineered solutions for missions around the globe and throughout the solar system. First Mode is also focusing on significant problems on Earth including the challenging issues of sustainability for the natural resources sector. In this episode of the Aerospace Engineering Podcast, Chris and I talk about:

• his background in engineering, including his time at NASA's Jet Propulsion Laboratory
• his past work on Mars rovers
• why we should go back to the Moon
• the space projects First Mode is currently involved with
• and First Mode’s growing engagement in the hydrogen sector

Carl Copeland is the founder of Möbius Aero, an electric air race team, and MμZ Motion, a developer of custom, high-performance electric motors. Carl has built various engineering teams and led innovation in the fields of IT, mechanical, magnetic, and electrical design. He has founded four companies and holds over 25 patents, and his most recent innovation, the Field Modulation Motion System, is a novel electric motor design that is significantly lighter and smaller than established electric motors of similar power and torque ratings. The Field Modulation Motion System achieves its high performance by using 18-phase field modulation rather than the three-phase modulation used in standard motors, essentially emulating six separate three-phase motors attached to a single shaft. Carl is putting his new engine design to the test in a new air racing series for electric aircraft known as Air Race E. In contrast to typical air racing series, in Air Race E aircraft race against each other on a course rather than flying isolated time trials. In the past, air races have been an invaluable means of developing aerospace technology in a competitive setting and Air Race E is re-awakening the spirit of competition by launching the first fully electric airplane race series. In this episode of the Aerospace Engineering Podcast, Carl and I talk about:

• his unique and auto-didactic background in engineering
• his goal of finding practical solutions to humanity's problems
• the Air Race E competition and the origin story of Carl’s racing team Möbius Aero
• the technical details and benefits of his new electric motor
• and the impact this has on airframe development
