3D PRINTING

Stratasys and Radford Collaborate to Create 500 3D-printed Parts for the Lotus Type 62-2 Coachbuilt Sports Car

Stratasys | February 17, 2022

Stratasys and Radford Collaborate
Stratasys Ltd., a company that makes polymer 3D printers, worked with luxury car brand Radford to make more than 500 parts for the Lotus Type 62-2 coach built. This is shown in the Discovery+ documentary Radford Returns.

Radford Returns, which is now available to view on Discovery+, chronicles the rebirth of coachbuilding craft via the use of 21st-century technology. The show has Ant Anstead as the host and Jenson Button as the former Formula One champion racing car driver. It chronicles the creation of the retro-modern Lotus Type 62-2 supercar. It's an ideal setup for cutting-edge 3D printing applications. Viewers get a behind-the-scenes look at the process, from design to prototype, tooling, and eventually, production components using 3D printing technologies from Stratasys FDM®, PolyJetTM, and stereolithography.

"Stratasys’ 3D printing technology gave us the design freedom and ability to easily create customized, one-off pieces and parts for these two prototype vehicles. It gave us the ability to fully embrace customized coachbuilding but with updated processes using 21st century technologies"

-host Ant Anstead.

Over 500 pieces were 3D-printed at the Radford Studio, automotive design and engineering business Aria Group, and Stratasys Direct Manufacturing to create the first two automobiles. The Radford team planned and monitored 3D prints across five global sites using Stratasys' GrabCAD ShopTM workflow software, utilizing a fleet of up to 20 different Stratasys 3D printers at any given moment—a genuine display of distributed manufacturing. Stratasys made a wide range of 3D printers, including the F900®, F770TM, Fortus 450mcTM, F370TM, and J55TM. Each of these printers was used for a different purpose.

"By integrating 3D printing technology into their shop, Radford has been able to bring 1960’s-style supercar automaking into the 21st century with the high-end, hyper-customized style and features that their customers expect in a vehicle of this caliber, It’s an extreme example of something we see every day in the auto industry. Everyone making investments in new vehicles wants a deeper level of customization, and 3D printing is helping make it possible."

-Pat Carey, Senior Vice President, Strategic Growth for Stratasys

The team constructed elements such as a substantial solid composite firewall sandwich core, produced in two halves on the Stratasys F900 printer using ULTEMTM 1010 resin. Without the assistance of a layup tool, the item was glued together into a single piece and then wrapped in carbon fiber. The firewall was intricately designed to accommodate inside speakers, a gasoline filler mount, and the baggage compartment. Furthermore, several external components, such as side mirror housings, radiator ducts, and body vents, were printed utilizing FDM® Nylon 12 Carbon Fiber and ASA materials. Many mounting brackets were printed in FDM Nylon 12 CF because of a variety of reasons, including the car's structural needs, the strict project timetable, and the freedom to be creative.

Anstead continued, When relaunching Radford, we set out to only work with world-class companies.”Lotus is a world-class company, Radford is a world-class company, so when we looked at 3D-printed parts, we looked to Stratasys.

Stratasys will continue to assist the Radford Lotus Type 62-2 project by providing 3D-printed manufacturing components using various 3D printing technologies, including FDM®, SAFTM, stereolithography, and P3TM Programmable PhotoPolymerization.

By using hybrid-additive manufacturing with Laser Metal Deposition (LMD), the advantages of conventional process chains and additive manufacturing can be combined. In this application, hybrid-additive manufacturing refers to the additive build-up of local features on conventionally manufactured components. This permits an efficient and demand-driven individualization at comparatively low cost. The video shows such a local reinforcement by LMD on an automotive suspension component.

Trucking Equipment Parts Manufacturer Partners with IMEC to Adopt and Implement Lean Manufacturing Principles into Their Processes

IMEC | August 19, 2022

Bonnell Industries has been a family owned, industry leader in the truck equipment industry in Northern Illinois for decades but struggled to embrace the concept of Lean Manufacturing. The team mostly operated under "we do it this way because it's what we know". It wasn't until William Hintzsche joined the team in November 2021 as the new COO, that things began to change. Noticing excess inventory and multiple non-value steps in processes, he realized it was time to attack the waste. Hintzsche knew it was in the company's best interest to reinforce lean principles and integrate it as part of the culture. He has worked with IMEC on many lean projects with former employers, and knows the breadth of lean expertise at IMEC, the conversation began about Bonnell undergoing a lean transformation. Hintzsche wanted the Bonnell team to understand how lean principles can improve processes, drive efficiency, and eliminate waste, which will help them deliver quality products and services and save money. Solution The process began with a full day learn and do workshop that combines classroom style instruction with a hands-on Simulation of production facility. In preparation for the simulations, both Bonnell and IMEC collaborated to incorporate safety protocols to ensure the health and safety for those in attendance. IMEC technical experts introduced the basic concepts of Lean Manufacturing to the team, demonstrating tools and techniques and how to effectively implement them in their operations and processes. The simulation portion involved participants applying the principles learned to their individual workspace and across the product line at the mock manufacturing plant created for this training. This technique utilized three shifts which illustrated the cause-and-effect relationships for the key lean principles discussed, while offering opportunities to make real-world decisions when making changes with workforce, budgets, etc. As with most change, resistance is natural. The team at Bonnell initially gave push back on the idea of a trainings to undergo a lean transformation. As they learned the basic concepts and participated in the simulation, they were able to see first-hand the benefits of embracing lean and how they could transfer what they were learning to their roles at Bonnell, streamlining their processes, and improving productivity and efficiency. About IMEC: IMEC is a team of improvement specialists and technicians dedicated to providing organizations in Illinois with the tools and techniques to create sustainable competitive futures. The experienced hands-on team at IMEC works closely with its clients to plan critical business improvements in the areas of Leadership, Strategy, Customer Engagement, Operations, and Workforce. IMEC, Illinois affiliate of the U.S Commerce NIST Manufacturing Extension Partnership (MEP) National Network, has demonstrated a return on investment that exceeds 19:1. This is made possible as organizations become more effective and efficient - and together with IMEC - excel toward enterprise excellence.
